Uses of Internet
Internet has been the most useful technology of the modern times which helps us not only in our daily lives, but also our personal and professional lives developments. The internet helps us achieve this in several different ways.
For the students and educational purposes the internet is widely used to gather information so as to do the research or add to the knowledge of any sort of subject they have. Even the business personals and the professions like doctors, access the internet to filter the necessary information for their use. The internet is therefore the largest encyclopedia for everyone, in all age categories.

What is Copywriting?
Copywriting is often confused with copyright, and thought to be of the same meaning or related to it. However there is no such association and copywriting itself is a separate term more commonly used in many aspects including the websites.
Copywriting involves the procedure of the promotion of any thing, may it be a person a business or even an opinion or an idea. It is also involved in various types of media may it be radio or television advertisement, or any other type. The soul reason for the promotion and the text is to convince the reader or the listen for a particular product or in simple terms marketing of a company or business, which may also be just a certain view point.
The copywriting can be done in a variety of different ways and means which include for example the World Wide Web, the taglines, scripts, television and radio etc. There are special copy writers associated with the work, who contribute their skills to provide with interesting ads, commercials, and other sort of advertising innovations.
There is a special meaning to the word copywriting for their use in the websites. It is associated with the special ways and means to write the wordings and format the text in website so as to reach a certain level in the higher rankings for the search engines. This type of copywriting is sometimes also referred to as the content writing and involves the use of the strategic keywords and their correct placement in the text for the web pages. This type of copywriting is usually referred to as the search engine optimization or the SEO.
The Hidden Diagnostic Panel
You probably already know about the Control Panel where Windows lets you change most of its settings, but did you know that there’s also a hidden diagnostic panel that tells you what’s going on with your computer right now?
It’s only accessible to those who know the special key combination: hold down Ctrl and Alt and then quickly press and release Delete. Go ahead, try it right now. CTRL, ALT, DEL.
This task manager includes all sorts of information about what programs are running, how much computer processing they’re using, how much network traffic your computer is running. You can use the buttons to force programs to quit and perform other important operations.
The most useful thing you can do with the task manager is find programs that are using too much computer processing (CPU) and force them to quit (if you don’t need them). For example, sometimes Web browsers or the Adobe Flash player will break and try to use all of your CPU—if that’s the case, simply find the program, highlight it, and click Force Quit.
You can also restart explorer.exe when all your desktop icons and task bar disappear.
Close Windows Quick
You’ve been surfing the Internet at work, but the boss just appeared around the corner—quick, what do you do?
You can close down any program quickly by pressing Alt-F4. But Alt-F4 isn’t just great for emergency situations, it’s also useful for closing all those other little applications you use, like the calculator.
Pro Multi-tasking
Here is one of my favorite computer tips and probably the easiest. Do you switch programs a lot? I do. I’m often trying to read my research notes and write an article at the same time, forcing me to switch between two windows a lot.
But switching between two windows takes a long time with the mouse. You need to take one hand off the keyboard, grab the mouse, scroll over to the next window, click, and put your hand back on the keyboard. Wouldn’t it be nice if you could switch windows without taking your hand off the keyboard? You can.
To switch windows, press Alt-Tab. The windows are lined up in the order of which you last used them, so pressing Alt-Tab will take you to the last window you used. Pressing Alt-Tab-Tab (two tabs) will take you to the window you used before that.
If you master Alt-Tab, you’ll be a master multi-tasker.
Advantages of IT

Features of an Operating System
Now that we are done with the types of operating system, let us take a look at what are the features that a particular operating system should have. Some of these features are a part of all operating systems, while some of them may or may not be available in the operating system you are using.
Managing Hardware and Software
As already mentioned, it is the computer operating system that causes the hardware and software in a computer to interact with each other. It is also the platform that causes one software in the computer to communicate with another. Once the operating system in a computer loads during the booting up process, other application software can be loaded into the computer.
Consistent Application Program Interface
Application Program Interface which software development professionals refer to as APIs allow the applications that run on one computer to run on another computer having the same operating system. It is thus important that the operating system has a consistent API. Undoubtedly, every operating system will have certain requirements, but it should be flexible enough to support computer hardware from different vendors.
Program Execution
It is up to the operating system to execute all the programs running in it. It is a rather complicated process. It may have to allow multitasking and allow different programs to run at the same time and share the system resources. It needs to allot RAM space to different applications running on the computer. The execution of more than one program may also require the operating system to prioritize the operations running on the computer.
Interrupts
The operating system needs to support a good number of interrupts to react with the immediate external environment. On receiving an interrupt it should have the capability to stop the current execution and start off a new process. Interrupting is not a very simple process. On receiving an interrupt, the computer operating system should be such that they immediately save the status of the current applications and start executing the code of that particular interrupt.
Memory Management
As already mentioned in the section on program execution, it is up to the computer operating system to provide memory to the different programs running on the computer. It has to prioritize and allocate memory to each application. Even when data is saved in a secondary storage device, it is the operating system, that decides how should that particular chunk of information be stored.
Accessing Data
The data required by any particular application software for its smooth running needs to be accessed by the operating system. The operating system stores data in a particular storage area in such a way that the data can be retrieved as and when required. The file system that different computers use may be different. The operating system needs to support these different file systems. Let us try to understand this with an example. Some computers may be using the FAT 32 file system, while some may be using the NTFS file system. Irrespective of which file system is being used, the operating system should provide support for the same. However, not all operating systems support all types of file systems.
Networking
We are in the age of networking. Computers need to communicate with each other. A computer without Internet is not even imaginable. It is the task of the operating system to provide the required networking features. It should have features to allow two or more computers to connect and form a network or connect to the Internet.
Security
Last but not the least, in today's age, security that an operating system should provide is undoubtedly one of its most important features. Right from setting passwords for logging in, to providing firewall protection; everything comes under the tasks of an operating system. Some network utilities may need file sharing, printer sharing and using TCP/IP protocols. Hence, it becomes very important for the computer operating system to provide proper security so that the computer's security is not compromised in such cases.
Let us now take a look at the details of the different operating systems available in the market. Here, we will take a look at only the most popular operating systems and of course, these are the operating systems which you would want to know about.

Clean out the prefetch folder
Windows XP uses a system called 'prefetch' to organize and preload some of the data necessary for commonly used applications and files. A folder called prefetch is used to store the information the operating system needs to carry out this operation.
After several months of use, the prefetch folder may become quite overloaded with older references to software and files that may no longer be in use.It's a good idea to manually empty the older files out of the prefetch folder every few months or so.
To do this: Navigate to 'c:\windows\prefetch' and delete all .
PF files that are older than a week or two.
Top 10 keyboard shortcuts everyone should know
Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, highlighting text with the keyboard and pressing Ctrl + C is much faster than taking your hand from the keyboard, highlighting the text using the mouse, clicking copy from the file menu, and then putting your hand back in place on the keyboard. Below are our top 10 keyboard shortcuts we recommend everyone memorize and use.
Ctrl + C or Ctrl + Insert
Copy the highlighted text or selected item.
Ctrl + V or Shift + Insert
Paste the text or object that's in the clipboard.
Ctrl + Z and Ctrl + Y
Undo any change. For example, if you cut text, pressing this will undo it. This can also often be pressed multiple times to undo multiple changes. Pressing Ctrl + Y would redo the undo.
Ctrl + F
Open the Find in any program. This includes your Internet browser to find text on the current page.
Alt + Tab or Alt + Esc
Quickly switch between open programs moving forward.
Tip: Press Ctrl + Tab to switch between tabs in a program.
Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab will move backwards. For example, if you are pressing Alt + Tab and pass the program you want to switch to, press Alt + Shift + Tab to move backwards to that program.
Tip: Windows Vista and 7 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the Window.
Ctrl + Back space and Ctrl + Left or Right arrow
Pressing Ctrl + Backspace will delete a full word at a time instead of a single character.
Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you wanted to highlight one word at a time you can hold down Ctrl + Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.
Ctrl + S
While working on a document or other file in almost every program pressing Ctrl + S will save that file. This shortcut key should be used frequently anytime you're working on anything important.
Ctrl + Home or Ctrl + End
Move the cursor to the beginning or end of a document.

Top Ten Antivirus Ratings
Most of these antivirus software have been tested extensively for their performance. The old versions have received ratings based on the performance to quickly detect viruses from infected systems and stop new viruses from infecting the computers. There is a very strong criteria that will be used to provide points to various antivirus software 2012. Another interesting factor that we are considering is the antivirus coupons, we will give scores to antivirus software companies that offer discount coupons from time to time. Although this is not a major factor, but many users value coupons because it is a good way to save money on security software. Although this factor will not inflate the original ratings, we are including it only to help people save money. These are the factors that will contribute to the scoring:

Which means, some antivirus programs slow down a computer. Computer users (specially gamers) like using antivirus software that does not degrade the performance of a computer system. They enjoy using the fastest antivirus software.
Stealth: Many viruses and spyware are designed to deactivate antivirus programs so that they are not detected. Antivirus software should quickly detect such a threat and stop the virus from harming the system files. Those antivirus software will receive higher score that can not only defend against known viruses but also protect a computer system from new and unknown virus and spyware.
Detection: A good antivirus program will quickly detect infection and will take the necessary steps to quarantine the infected files in order to stop the virus from spreading to other system files. Only if security software has the capabilities of detecting infection, it can stop a virus/spyware. So this is a major aspect of security software. Many poorly designed security software cannot detect all forms of threat. However, only those antivirus software will be included in our top ten antivirus 2012 list that are capable of detecting all sorts of threats.
Technical Support: We will also provide scores depending upon the type of technical support and customer service provided by the antivirus software manufacturer.

How to Reset Your Forgotten Windows Password the Easy Way
Forgetting your password is never any fun, but luckily there’s a really easy way to reset the password. All you need is a copy of the Windows installation disk and one simple command line trick.
Resetting Your Forgotten Windows Password
Boot off the Windows disk and select the “Repair your computer” option from the lower left-hand corner.
Follow through until you get to the option to open the Command Prompt, which you’ll want to select.
First you’ll want to type in the following command to backup the original sticky keys file:
copy c:\windows\system32\sethc.exe c:\
Then you’ll copy the command prompt executable (cmd.exe) over top of the sticky keys executable:
copy c:\windows\system32\cmd.exe c:\windows\system32\sethc.exe
Now you can reboot the PC.
Resetting the Password
Once you get to the login screen, hit the Shift key 5 times, and you’ll see an administrator mode command prompt.
Now to reset the password—just type the following command, replacing the username and password with the combination you want:
net user geek MyNewPassword
That’s all there is to it. Now you can login.
Of course, you’ll probably want to put the original sethc.exe file back, which you can do by rebooting into the installation CD, opening the command prompt, and copying the c:\sethc.exe file back to
c:\windows\system32\sethc.exe.
How to Remove Shortcut Arrow on Icons in Windows (Include Desktop Items)

What is Computer Network?
Two or more computers connected together through a communication media form a computer network.
The computers are connected in a network to exchange information and data. The computers connected in a network can also use resources of other computers.
Computer Network Components
There are different components of a network. Following are the basic components of network.
1. Server:
Powerful computers that provides services to the other computers on the network.
2. Client:
Computer that uses the services that a server provides. The client is less powerful than server.
3. Media:
A physical connection between the devices on a network.
4. Network Adopter:
Network adopter or network interface card (NIC) is a circuit board with the components necessary for sending and receiving data. It is plugged into one of the available slots on the Pc and transmission cable is attached to the connector on the NIC.

Information Technology in Education
INTRODUCTION Information Technology in Education, effects of the continuing developments in information technology (IT) on education.
The pace of change brought about by new technologies has had a significant effect on the way people live, work, and play worldwide. New and emerging technologies challenge the traditional process of teaching and learning, and the way education is managed. Information technology, while an important area of study in its own right, is having a major impact across all curriculum areas. Easy worldwide communication provides instant access to a vast array of data, challenging assimilation and assessment skills. Rapid communication, plus increased access to IT in the home, at work, and in educational establishments, could mean that learning becomes a truly lifelong activity—an activity in which the pace of technological change forces constant evaluation of the learning process itself.
Significance of IT in education
Access to variety of learning resources
In the era of technology. IT aids plenty of resources to enhance the teaching skills and learning ability. With the help of IT now it is easy to provide audio visual education. The learning resources are being widens and widen. Now with this vivid and vast technique as part of the IT curriculum, learners are encouraged to regard computers as tools to be used in all aspects of their studies. In particular, they need to make use of the new multimedia technologies to communicate ideas, describe projects, and order information in their work.
Immediacy to information
IT has provided immediacy to education. Now in the year of computers and web networks the pace of imparting knowledge is very very fast and one can be educated anywhere at any time. New IT has often been introduced into well-established patterns of working and living without radically altering them. For example, the traditional office, with secretaries working at keyboards and notes being written on paper and manually exchanged, has remained remarkably stable, even if personal computers have replaced typewriters.
Any time learning
Now in the year of computers and web networks the pace of imparting knowledge is very very fast and one can be educated .One can study whenever he wills irrespective of whether it is day or night and irrespective of being in India or in US because of the boom in IT.
Collaborative learning
Now IT has made it easy to study as well as teach in groups or in clusters. With online we can be unite together to do the desired task. Efficient postal systems, the telephone (fixed and mobile), and various recording and playback systems based on computer technology all have a part to play in educational broadcasting in the new millennium. The Internet and its Web sites are now familiar to many children in developed countries and among educational elites elsewhere, but it remains of little significance to very many more, who lack the most basic means for subsistence.
Multimedia approach to education
Audio-Visual Education, planning, preparation, and use of devices and materials that involve sight, sound, or both, for educational purposes. Among the devices used are still and motion pictures, filmstrips, television, transparencies, audiotapes, records, teaching machines, computers, and videodiscs. The growth of audio-visual education has reflected developments in both technology and learning theory.
Studies in the psychology of learning suggest that the use of audio-visuals in education has several advantages. All learning is based on perception, the process by which the senses gain information from the environment. The higher processes of memory and concept formation cannot occur without prior perception. People can attend to only a limited amount of information at a time; their selection and perception of information is influenced by past experiences. Researchers have found that, other conditions being equal, more information is taken in if it is received simultaneously in two modalities (vision and hearing, for example) rather than in a single modality. Furthermore, learning is enhanced when material is organized and that organization is evident to the student.
These findings suggest the value of audio-visuals in the educational process. They can facilitate perception of the most important features, can be carefully organized, and can require the student to use more than one modality.
Authentic and up to date information
The information and data which are available on the net is purely correct and up to date.
Internet, a collection of computer networks that operate to common standards and enable the computers and the programs they run to communicate directly provides true and correct information.
Online library
Internets support thousands of different kinds of operational and experimental services one of which is online library. We can get plenty of data on this online library.
As part of the IT curriculum, learners are encouraged to regard computers as tools to be used in all aspects of their studies. In particular, they need to make use of the new multimedia technologies to communicate ideas, describe projects, and order information in their work. This requires them to select the medium best suited to conveying their message, to structure information in a hierarchical manner, and to link together information to produce a multidimensional document.
Distance learning
Distance Learning, method of learning at a distance rather than in a classroom. Late 20th-century communications technologies, in their most recent phases multimedia and interactive, open up new possibilities, both individual and institutional, for an unprecedented expansion of home-based learning, much of it part-time. The term distance learning was coined within the context of a continuing communications revolution, largely replacing a hitherto confusing mixed nomenclature—home study, independent study, external study, and, most common, though restricted in pedagogic means, correspondence study. The convergence of increased demand for access to educational facilities and innovative communications technology has been increasingly exploited in face of criticisms that distance learning is an inadequate substitute for learning alongside others in formal institutions. A powerful incentive has been reduced costs per student. At the same time, students studying at home themselves save on travel time and other costs.
Whatever the reasoning, distance learning widens access for students unable for whatever reason (course availability, geographical remoteness, family circumstances, individual disability) to study alongside others. At the same time, it appeals to students who prefer learning at home. In addition, it appeals to organizers of professional and business education, providing an incentive to rethink the most effective way of communicating vital information.
Better accesses to children with disabilities
Information technology has brought drastic changes in the life of disabled children. IT provides various software and technique to educate these poor peoples. Unless provided early with special training, people profoundly deaf from birth are incapable of learning to speak. Deafness from birth causes severe sensory deprivation, which can seriously affect a person's intellectual capacity or ability to learn. A child who sustains a hearing loss early in life may lack the language stimulation experienced by children who can hear. The critical period for neurological plasticity is up to age seven. Failure of acoustic sensory input during this period results in failure of formation of synaptic connections and, possibly, an irremediable situation for the child. A delay in learning language may cause a deaf child's academic progress to be slower than that of hearing children. The academic lag tends to be cumulative, so that a deaf adolescent may be four or more academic years behind his or her hearing peers. Deaf children who receive early language stimulation through sign language, however, generally achieve academically alongside their hearing peers.
The integration of information technology in teaching is a central matter in ensuring quality in the educational system. There are two equally important reasons for integrating information technology in teaching. Pupils must become familiar with the use of information technology, since all jobs in the society of the future will be dependent on it, and information technology must be used in teaching in order to improve its quality and make it more effective.
INTRODUCTION
The information society challenges the education system. In recent years, the speedy, effective and global communication of knowledge has created a new foundation for co-operation and teamwork, both nationally and internationally. The increasing role played by information technology in the development of society calls for an active reaction to the challenges of the information society.
Already, new and greater demands are being made as to the core qualifications of individuals, as well as to their understanding and knowledge of the consequences of the introduction of information technology for the work and organisation of a company. Companies are no longer forced to gather all their functions in one place. The knowledge-intensive functions such as development and marketing can be sited in countries where the labour market can supply highly educated employees, whilst production itself can be moved to low wage countries. The result is the efficient handling, processing, co-ordination and administration of company resources, which is decisive for the competitiveness of the company.In a society which is becoming increasingly dependent on information and the processing of knowledge, great demands are therefore made that the individual should have a solid and broad educational foundation on which to build. Educational policy in the information society must ensure that:
IT qualifications are developed by means of their integration in all activities in the education sector and
The individual citizen must have an active and critical attitude to developments and not passively allow technological development to set the pace.
IT educational policy must ensure:
Up-to-date qualifications in the information society
Up-to-date qualifications gained against the background of a high general level of education in the population will be decisive if Denmark is to maintain competitiveness and its share of the global labour market in the information society. IT skills and IT understanding are thus central prerequisites for the individual, both now and especially in the future.
The advantage of using information technology is that time-consuming work routines can increasingly be performed by means of this technology and time can thus be devoted instead to communicating and informing, to the processing of information and the production of knowledge.
PC Troubleshooting Tips Why is My PC Crashing?
Nothing can put a damper on productivity quite like a computer that crashes on a regular basis. Sometimes, a crash is preceded by the dreaded “blue screen of death” or another warning; other times, a computer simply shuts off without any warning at all. In either case, the end result is a whole lot of frustration, aggravation and lost work. If your computer has been crashing frequently, you’d probably like to put an end to it. Unfortunately, getting to the bottom of things if often easier said than done. The following tips about improving your computer’s performance, though, are excellent places to begin.
Possibility #1: Corrupted System Registry Files
Every Windows-based PC has something called a Windows registry. The registry contains several files that are integral to the performance and operation of your computer. Over time, some of those files can become corrupted, be misplaced or get lost altogether. When that happens, the system registry becomes compromised – and frequent crashes are all-too-common symptoms. The best way to rule this possibility in or out is by running a Windows registry cleaning program. Such programs scan your Windows registry for problems then automatically make repairs. If you run a registry cleaner and the crashes persist, they are probably being caused by a different issue.
Possibility #2: Disorganized Files
Windows operating systems handle file organization in a way that isn’t very intuitive. Basically, they break files up and fit them into gaps in the computer’s memory. As time goes by, these disorganized files can prompt frequent crashes. Luckily, a great optimization solution is built right into Windows-based PCs: the disk defragmentation utility. Although its location on a computer varies, you can generally locate it within the System and Security section inside the Control Panel. By running a defrag once every few months, you may be able to keep those pesky computer crashes at bay.
Possibility #3: Malicious Software
Malicious software can take many different forms. Sometimes, it’s a virus that is accidentally unleashed after opening a strange email; other times, its adware that tags along with other information that is automatically downloaded from a website. Whatever type it is, there’s no question that malicious software can wreak havoc on a computer’s performance. Happily, there are many topnotch programs out there that regularly scan your computer for the presence of such problems – and that help guard against them, too. Buy one, install it and use it regularly; your crash issues may come to an end.
Possibility #4: Too Little Available Memory
When you buy a new computer, it feels like there’s no end to the amount of memory that it has. Of course, this isn’t true at all. As never-ending as the available memory on your PC may initially seem, the fact is that it can be depleted with incredible speed. You can find out for sure by checking the information within “My Computer.” If it appears that your available memory is low, you can use a PC cleanup program to remove unnecessary files; such programs remove things like temporary Internet files and other file debris that can suck away much-needed memory.
Possibility #5: Overheating
If you’ve run through all of the preceding possibilities and continue experiencing frequent crashes, a hardware issue could be to blame. An easy one to rule out is overheating. A computer’s CPU, or central processing unit, includes a fan that is designed to keep it running cool. Sometimes, the fan wears down and doesn’t work as efficiently; other times, it’s just not able to handle the work that your computer has to do. In either case, buying a bigger, better fan isn’t very expensive. If it puts an end to your PC crashing problem, it will have been more than worth it.
Don’t Put Up with Frequent Crashes!
As discussed, frequent computer crashes can be triggered by a wide variety of issues. Luckily, many of these issues are relatively easy to remedy. Work your way through the preceding list; chances are, you’ll be able to pinpoint the problem and put an effective cure to work. Nine times out of ten, a computer simply needs a little bit of routine maintenance to get it back on track again. In the future, keep these points in mind. Any time you buy a new computer, keep up with its basic maintenance right from the get-go. By doing that, you could avoid “blue screen of death” and crashing problems altogether – and that’s something that you’re bound to appreciate!
What is Computer Network?
Two or more computers connected together through a communication media form a computer network.
The computers are connected in a network to exchange information and data. The computers connected in a network can also use resources of other computers.
Computer Network Components
There are different components of a network. Following are the basic components of network.
1. Server:
Powerful computers that provides services to the other computers on the network.
2. Client:
Computer that uses the services that a server provides. The client is less powerful than server.
3. Media:
A physical connection between the devices on a network.
4. Network Adopter:
Network adopter or network interface card (NIC) is a circuit board with the components necessary for sending and receiving data. It is plugged into one of the available slots on the Pc and transmission cable is attached to the connector on the NIC.
5. Resources:
Any thing available to a client on the network is considered a resource .Printers, data, fax devices and other network devices and information are resources.
6. User:
Any person that uses a client to access resources on the network.
8. Protocols:
These are written rules used for communications. They are the languages that computers use to talk to each other on a network
Intel Core i7
Intel Core i7 is an Intel brand name for several families of desktop and laptop 64-bit x86-64 processors using the Nehalem, Westmere, Sandy Bridge and Ivy Bridge microarchitectures. The Core i7 brand is targeted at the business and high-end consumer markets for both desktop and laptop computers, and is distinguished from the Core i3 (entry-level consumer), Core i5 (mainstream consumer), and Xeon (server and workstation) brands.
The Core i7 name was introduced with the Bloomfield Quad-core processor in late 2008.In 2009 new Core i7 models based on the Lynnfield desktop quad-core processor and the Clarksfield quad-core mobile were added, and models based on the Arrandale dual-core mobile processor were added in January 2010. The first six-core processor in the Core lineup is the Gulftown, which was launched on March 16, 2010. Both the regular Core i7 and the Extreme Edition are advertised as five stars in the Intel Processor Rating. In January 2011, Intel released the second generation of Core i7 processors. Both the first and second generation of Intel Core i7 processors are rated as 5 stars in the Intel processor rating. The second generation of Intel core processors are based on the "Sandy Bridge" core and are set to be updated in January1 2012 with "Ivy Bridge". 1Footnote: It has not yet been launched, as of 2012-04-22
In each of the first three microarchitecture generations of the brand, Core i7 has family members using two distinct system-level architectures, and therefore two distinct sockets (for example, LGA 1156 and LGA 1366 with Nehalem). In each generation, the highest-performing Core i7 processors use the same socket and QPI-based architecture as the low-end Xeon processors of that generation, while lower-performing Core i7 processors use the same socket and PCIe/DMI/FDI architecture as the Core i5.
"Core i7" is a successor to the Intel Core 2 brand.Intel representatives stated that the moniker Core i7 is meant to help consumers decide which processor to purchase as the newer Nehalem-based products are released in the future.

About Keyloggers
The term ‘keylogger’ itself is neutral, and the word describes the program’s function. Most sources define a keylogger as a software program designed to secretly monitor and log all keystrokes. This definition is not altogether correct, since a keylogger doesn’t have to be software – it can also be a device. Keylogging devices are much rarer than keylogging software, but it is important to keep their existence in mind when thinking about information security.
Legitimate programs may have a keylogging function which can be used to call certain program functions using “hotkeys,” or to toggle between keyboard layouts (e.g. Keyboard Ninja). There is a lot of legitimate software which is designed to allow administrators to track what employees do throughout the day, or to allow users to track the activity of third parties on their computers. However, the ethical boundary between justified monitoring and espionage is a fine line. Legitimate software is often used deliberately to steal confidential user information such as passwords.
Most modern keyloggers are considered to be legitimate software or hardware and are sold on the open market. Developers and vendors offer a long list of cases in which it would be legal and appropriate to use keyloggers, including:
Parental control: parents can track what their children do on the Internet, and can opt to be notified if there are any attempts to access websites containing adult or otherwise inappropriate content;
Jealous spouses or partners can use a keylogger to track the actions of their better half on the Internet if they suspect them of “virtual cheating”;
Company security: tracking the use of computers for non-work-related purposes, or the use of workstations after hours;
Company security: using keyloggers to track the input of key words and phrases associated with commercial information which could damage the company (materially or otherwise) if disclosed;
Other security (e.g. law enforcement): using keylogger records to analyze and track incidents linked to the use of personal computers;
Other reasons.
However, the justifications listed above are more subjective than objective; the situations can all be resolved using other methods. Additionally, any legitimate keylogging program can still be used with malicious or criminal intent. Today, keyloggers are mainly used to steal user data relating to various online payment systems, and virus writers are constantly writing new keylogger Trojans for this very purpose.
Furthermore, many keyloggers hide themselves in the system (i.e. they have rootkit functionality), which makes them fully-fledged Trojan programs.
As such programs are extensively used by cyber criminals, detecting them is a priority for antivirus companies. Kaspersky Lab’s malware classification system has a dedicated category for malicious programs with keylogging functionality: Trojan-Spy. Trojan-Spy programs, as the name suggests, track user activity, save the information to the user’s hard disk and then forward it to the author or ‘master’ of the Trojan. The information collected includes keystrokes and screen-shots, used in the theft of banking data to support online fraud.
Must Use Defragmentation
Defragmentation is a process that reduces the amount of fragmentation. It does this by physically organizing the contents of the mass storage device used to store files into the smallest number of contiguous regions (fragments). It also attempts to create larger regions of free space using compaction to impede the return of fragmentation. Some defragmentation utilities try to keep smaller files within a single directory together, as they are often accessed in sequence.
Defragmentation is advantageous and relevant to file systems on electromechanical disk drives. The movement of the hard drive's read/write heads over different areas of the disk when accessing fragmented files is slower, compared to accessing the entire contents of a non-fragmented file sequentially without moving the read/write heads to seek other fragments.

How to Protect Your Computer
Below are some key steps to protecting your computer from intrusion:
Keep Your Firewall Turned On: A firewall helps protect your computer from hackers who might try to gain access to crash it, delete information, or even steal passwords or other sensitive information. Software firewalls are widely recommended for single computers. The software is prepackaged on some operating systems or can be purchased for individual computers. For multiple networked computers, hardware routers typically provide firewall protection.
Install or Update Your Antivirus Software: Antivirus software is designed to prevent malicious software programs from embedding on your computer. If it detects malicious code, like a virus or a worm, it works to disarm or remove it. Viruses can infect computers without users' knowledge. Most types of antivirus software can be set up to update automatically.
Install or Update Your Anti spyware Technology: Spyware is just what it sounds like—software that is surreptitiously installed on your computer to let others peer into your activities on the computer. Some spyware collects information about you without your consent or produces unwanted pop-up ads on your web browser. Some operating systems offer free spyware protection, and inexpensive software is readily available for download on the Internet or at your local computer store. Be wary of ads on the Internet offering downloadable antispyware—in some cases these products may be fake and may actually contain spyware or other malicious code. It's like buying groceries—shop where you trust.
Keep Your Operating System Up to Date: Computer operating systems are periodically updated to stay in tune with technology requirements and to fix security holes. Be sure to install the updates to ensure your computer has the latest protection.
Be Careful What You Download: Carelessly downloading e-mail attachments can circumvent even the most vigilant anti-virus software. Never open an e-mail attachment from someone you don't know, and be wary of forwarded attachments from people you do know. They may have unwittingly advanced malicious code.
Turn Off Your Computer: With the growth of high-speed Internet connections, many opt to leave theircomputers on and ready for action. The downside is that being "always on" renders computers more susceptible. Beyond firewall protection, which is designed to fend off unwanted attacks, turning thecomputer off effectively severs an attacker's connection—be it spyware or a botnet that employs yourcomputer's resources to reach out to other unwitting users
