Computer Security

 

What is Computer Security?

Computer Security is a branch of technology known as information security as applied to computers. Information security means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The objective of computer security varies and can include protection of information from theft or corruption, or the preservation of availability, as defined in the security policy.

Technological and managerial procedures applied to computer systems to ensure the availability, integrity and confidentiality of information managed by the computer system

 

Computer security imposes requirements on computers that are different from most system requirements because they often take the form of constraints on what computers are not supposed to do.

Typical approaches to improving computer security can include the following:

Physically limit access to computers to only those who will not compromise security.

Hardware mechanisms that impose rules on computer programs, thus avoiding depending on computer programs for computer security.

Operating system mechanisms that impose rules on programs to avoid trusting computer programs.

Programming strategies to make computer programs dependable and resist subversion.

Computer Security has three Layers:

o Hacking

o Cracking

o Phreaking

 

Hacking:

Unauthorized use or attempts to circumvent or bypass the security mechanisms of an information system or network.

Computer hacking always involves some degree of infringement on the privacy of others or damage to computer-based property such as files, web pages or software.

The impact of computer hacking varies from simply being simply invasive and annoying to illegal.

 

Cracking:

The act of breaking into a computer system.

Software Cracking is the modification of software to remove protection methods: copy prevention, trial/demo version, serial number, hardware key, CD check or software annoyances like nag screens and adware.

The most common software crack is the modification of an application's binary to cause or prevent a specific key branch in the program's execution.

 

Phreaking:

The art and science of cracking the phone network.

 

 

Security by design:

The technologies of computer security are based on logic. There is no universal standard notion of what secure behavior is. "Security" is a concept that is unique to each situation. Security is extraneous to the function of a computer application, rather than ancillary to it, thus security necessarily imposes restrictions on the application's behavior.

There are several approaches to security in computing; sometimes a combination of approaches is valid:

Trust all the software to abide by a security policy but the software is not trustworthy (this is computer insecurity).

Trust all the software to abide by a security policy and the software is validated as trustworthy (by tedious branch and path analysis for example).

Trust no software but enforce a security policy with mechanisms that are not trustworthy (again this is computer insecurity).

Trust no software but enforce a security policy with trustworthy mechanisms.

 

12 tips for computer security:

Update / patch ALL your software every now and then!

Check / adjust ALL your settings so they are safe, since they ARENT by default!

Use firewall, like ZoneAlarm to control what goes in and out from your computer!

Use good passwords: at least 13marks long, containing both letters and numbers. Remember to change your password every few months atleast and dont ever use the same password in two places!

Get a good antivirus program: NOD32, F-Secure or Norton Antivirus and keep it updated!

Don’t open or execute files that you are not 100% sure are absolutely safe nomatter where or how you get them.

Wipe your historyfiles (like cookies, internet history and temporary files, etc.), logs and personal files, with specific wiping program (like Eraser) instead of just deleting them.

Use encryption to enhance your privacy! Use encrypted email (like Hushmail or Ziplip), www-surfing and encrypt sensitive files on your computer (PGP).

When you are finished using some internet-based service like email, sign out of it rather than just closing your browser! Also, when you leave your computer, make sure that none of such programs or connections are left open that someone could abuse. In WindowsNT/2k/XP, press Windowskey+L to lock the workstation.

Don’t use public computers for anything you need to type in your logins, they usually have Trojan horses that capture your passwords.

Make backups and store them in safe place! Easiest way to do a total-backup is to make an "Image" of your harddrive or partition and store it on safe location, but floppies will usually be just fine for storing documents, etc.

Install and Use a Hardware Firewall

How To Speed Up Internet Explorer

Nobody likes a slow internet browser, and when it comes to slow Internet Explorer has a bad reputation of being slow, clunky and an overall pain. Browsers such as Google Chrome or Fire Fox offer a much better user experience (well at least in my opinion), but if you insist on using Internet Explorer here are a couple ways to speed it up.

The first thing you can do is remove all the extra add-ons explorer likes to jam into its browser. The more of these add-ons you have the slower that browser becomes. To remove any unwanted add ons click on tools. If you're using Internet Explorer 9 it will look like a small gear in the top right corner of the page.

From their click it and scroll down to where it says manage add-ons, click that and a list of all the add-ons currently installed on your browser will be displayed. From here simply scroll down the list and click on every add on you want to disable.

Another option that's available is something called Google Chrome Frame. It's a free download like everything Google makes. Its purpose is to speed up explorer, especially older versions 7 and 8. It also allows its users to be able to use HTML5 and other technologies that Internet Explorer doesn't support. Simply download it and it should start working automatically.

You can also change the setting so that it doesn't check for new versions of cached sites. To do this click on internet options (click the gear looking button again also known as tools) go to browsing history and click on settings. From here either choose under temporary internet files one of the following

a. Every time I start Internet Explorer, which might slow down the browser the first time you run it. It should run faster after though.

b. Never, this won't sync any cached pages.

And finally you can also speed up Internet Explorer by sorting through your favourites list and deleting any links you don't use anymore. A large number of favourites can have an impact on its speed and slow it down, so it's always a good idea to spend a little time and clean out you're favorites list.

Hopefully these tips will help if your currently using any version of explorer and drastically improve that browsers speed and load time. Which will keep you from ripping you're hair out in frustration.

New Audio Equipment for Conferences

Conferences are big in many companies. Those who are constantly using such equipments, building their own set up can be an advantage. If you think your business can benefit from such investments, the rest of this article will give you just a few pointers but will be beneficial in deciding if building a new audio equipment set up for a conference should be considered.

The basic concept of a simple sound system consists of sound input devices, output devices and amplifiers.

Input Devices

These are microphones, the most popular of which are the dynamic microphones. This is a wired microphone device commonly seen in every stage performances and in musical television performances. A wireless microphone is the same as the dynamic brand but without the connecting cables. These have an FM radio transmitter device to send signals thereby also called as a radio microphone. Lavalier microphones are the hands-free devices which can be seen being used by television newscasters attached to their blouse or suit also called as lapel. Most lapels now are also wireless, making them the most convenient to be used by presenters who need to be all over the stage. CD/DVD players are both audio and video input devices.

Output Devices

Output devices are loudspeakers. The number of units to be needed will depend on the venue of the conference and the number of expected attendees. These equipments will be the bulk of the whole system. Makers of loudspeakers have come up with lightweight and small designs but maybe unsuitable for a large audience. Investing on a good number of loudspeakers can make your set up most applicable for a wide variety and volume of conferences.

Power Amplifiers

Power amplifiers are the drivers of loudspeakers. Aside from amplifying sounds, most units are also made to protect speakers from signal and thermal overloads. This eliminates the need for limiters which is commonly used to prevent signal overloads.

After acquiring the basic equipments, the next agenda is to assign technicians who can manage the whole set up. Consider putting up a group of not less than 3 people to manage the system while the event is on going. These should be trained technicians who know how to troubleshoot when a glitch arise.

For large companies, investing on a new audio equipment set up for a conference can be a good investment. Renting these types of systems always eat up a big chunk from corporate event budgets. But for small and medium-sized organizations, renting these equipments can be costly. Spending for the maintenance and putting additional people on the payroll list entails losses instead of a gain.

Soy Ink Could Be the Future of Printing

Consumer outlook on green incentives has sparked new interest in the business world as to how to efficiently promote environmentally friendly practices without increasing cost of products.

Since 1970, most American newspapers have switched from fossil fuel-based inks to soy ink as an alternative to rising petroleum costs. In the past two years, soy-based ink has expanded its market into homes.

As it begins to reach these settings, consumers are forced to weigh the pros and cons of purchasing soy ink toner and printer cartridges. On one hand, it releases less volatile organic compounds (VOCs), which is better for our planet, spreads easier and requires less of it to print. On the other hand, some of the VOCs found in petroleum ink help it dry faster and prevent smudging. That means printing out pictures of your kids on nice glossy paper could become a lengthy project.

Consumers interested in switching over to soy ink were initially wary of the potential spike in cost. However, with an expanded interest in the production of these soy cartridges, recent price comparisons show that soy cartridge prices have decreased and are equivalent to those of petroleum ink cartridges.

Printing with this new ink cartridge at home is a relatively new concept, but once consumers got past the initial misconception that it will cost more, the pros seem to outweigh the cons. In terms of looks, soy produces a much more vibrant colored ink than petroleum. It also leaves less residue, which allows paper to be recycled easier as it is de-inked and broken down into a pulp.

Additionally, pre-existing technology could be used to make use of the renewable soybean resource rather than the continued production of fossil fuel-based inks. In the grand scheme of printing, the use of soy ink will only impact our planet when used in bulk. Newspapers and other mass-produced texts that use soy ink cartridges will help combat past littering problems, too, because soy ink is biodegradable.

For a consumer this could be a perfect way to participate in an ever-growing green society. Not only does this option promote a green reputation, but studies show that soy ink lasts longer and prints at a higher quality than that of the traditional ink cartridges, especially on recycled paper. Soy ink is growing in popularity and with a higher demand of green options for the home and office, it could become a viable replacement for petroleum ink in the future.

Would You Believe Dust?

"Uh-oh," I said quietly to myself. Of course now my husband is listening and he says, "Uh-oh what?" "Nothing," I say, not sounding very confident. "Well, it must be something. What happened?" says he. "I'm not sure, but I think our computer has decided to take a permanent vacation," I replied.

Our computer had been doing weird things over the previous week. Things like taking forever to boot up, taking forever to shut down, shutting down altogether in the middle of whatever, sluggishness, and complete unco-operation. We thought it was "just time." Time to upgrade what we have or buy a new computer and we couldn't afford either one at the time.

A friend of ours who knows his way around computers came over to take a look at it. He asked me to take the cover off the tower, then he said he was going to try blowing the dust out of it first. I'm thinkin', "C'mon! Enough foolin' around! I want/need to get on my computer!" So he blew a dust storm out of the tower with our air compressor, put the cover back on the tower and fired 'er up. I squeezed my eyes shut and gritted my teeth hoping for the best. When I opened my eyes again, not only was the computer running, but the desktop was already up and completely running! It was lagging anymore and it was booting up and shutting down like the speedy demon it is.

Dust. Dust. I can't believe it was just dust. I was so relieved that the problem was so simple and easily fixed. Yay! Which of course got me thinking about other electronics and appliances. By blowing the dust out of our refrigerator it now runs more quietly and efficiently. Our t.v. stopped making this annoying, high-pitched beeping sound. My box fan I must have running 24/7 regained the highest speed. Now I keep a lot of things around the house blown out about every six months.

My mother took her computer to a computer repair guy because her computer was doing the same thing mine was. She said he did everything but blow the damn thing up and it still refused to work. I asked her if he blew the dust out of it with an air compressor and no, he hadn't. I told her to bust out the ol' air compressor and blow the dust out of it. She did and it fired up and worked just as it was supposed to with none of the previous problems. I guess the computer guy was sick that day...

So before you panic and run out and spend exorbitant amounts of money on repairs, software and anti-viruses, look at the vent on the side of your tower. If you can see dust there, I promise you, there is dust throughout and it is a huge burden to your computer (or other electronics and appliances). Dust slows down the fans, conducts electricity, and causes appliances and electronics to overheat. Sort of like making sure something is plugged in before you start troubleshooting anything else, blow the dust out and take troubleshooting from there. After that, a good blow job to your appliances and electronics about every 3-6 months and it will keep them running cool, quiet, and efficient!

Top Laptop Choices for College Students

College life couldn't be the same without a gadget to help students find information for in their studies, write papers and also interact with other students and family, play games or watch movies and listen to music. That's why any student should not be without a laptop.

But when it comes to actually choosing a laptop for a student, how would one know what to choose from the wide array of available mobile computer choices?

Since it has to be able to do a bit of each, it should be something like an everyday use sort of laptop, but maybe a bit better if there are extra needs to be attended to.

The first thing any student needs to be able to do with a laptop is write papers and search for relevant information on the web to help them in their studies. These simple tasks can be accomplished by any laptop, so you'll just have to get a bit more specific about those needs that need attending.

Students going to arts or design colleges might need a better laptop with them, since they will be surely working with graphic design application, which in most cases need a lot more resources from the whole system than average apps like the Office Suite require. In this case, you should look for a laptop equipped with a dual or quad core processor, with at least 3GB or RAM installed and a dedicated graphics card with up to 1GB of memory. This sort of laptop will run most graphic design applications, so the arts / design student won't run into trouble any time soon.

If you'd also like to play games on a laptop, but not just any games, the modern 3D ones, then the options tend to narrow down a bit to a few elite laptops from renowned manufacturers. These are the gaming beasts that only a few people can afford, but they look and work with stellar performance in any given situation. It doesn't matter what you need the laptop for, one of these will run any application or game without any problem.

All in all you need to pay special attention to what you purchase before running into trouble from lack of system resources. The best student laptop is a laptop that aligns itself with all the needs and demands the student might have from a mobile computer during their college years.

Why the Cheap Cell Phone Works

With the changing financial position on a global level, there are several people who are looking for some cheap phones. Just a decade ago, buying a cheap cell phone was cheap and unclassy, but it has become quite an acceptable trait today. In fact, even the most prominent mobile manufacturers have now come out with some inexpensive models, which provide the common features that are available in any cell.

Here are some of the reasons why the cheap phone works. People from all walks of life today require a cell phone. The blue collared, the white collared, and even the people who are not working. Not all of them would be able to afford the high priced mobiles. Therefore, cheap cell phones become a necessity in the market. Therefore, the financial conditions of many of the people who would like a cell phone and require it is one of the main reasons why the cheap cell phone works.

Secondly, a cheap phone works because of the changing face of technology. A new kind of technology or an enhancement is released routinely, making the previous technology obsolete. Therefore, the older technology mobile phones generally lose their price, thereby creating a market where technology is available at a lower price. This is another reason why cheap mobiles work, the technology that they run on become obsolete very quickly, and therefore the cheap phone running that technology becomes cheaper.

The third reason is the features of the phone. Though a phone may have hundreds of features, the most that people use are around ten or twelve. Therefore, there are some phones that only offer these ten or twelve features, and the price of the phone is set on the number of features that are available in the cell phone. So, there are many cheap and economic phones that have a lesser number of features and services provided in the market.

These are the three reasons why a cheap phone still works in the market, even though there is a splurge of expensive gadgets and brands in the market almost every other month. Though there are several cheap mobiles available, you should consider whether the cheap ones are perfect for your business or not. Some mobile phones, though cheap, may not have all the features and services that you would like. Other mobile phones may not have the warranty or the safety precautions that an expensive mobile phone would have. So, keeping all of these aspects in mind, one should consider which cell would suit them the best

The Ultimate Laptop Bag - What to Carry With Your Computer

A laptop bag should contain within it everything that you could need in order to use your laptop. This is a portable bag in which you will keep all of your belongings that you might use alongside your laptop itself, and in theory it should mean that you have everything you could need for your desk with you (or its portable counterpart). With a well-stocked laptop bag you will be able to stop and do any kind of work no matter where you are. Here we will look at what you should pack to make this a possibility.

First of all your laptop bag should of course contain a laptop. This is going to be the centerpiece of your items and what everything will work around. Make sure that it is small enough to carry easily while being powerful enough to provide everything you need it for. As a general rule a 10'' screen provides you with an almost optimum balance of portability while still having a big enough keyboard to type quickly and all the usual bells and whistles. A laptop this size can in fact help you to type more quickly in many cases - simply because the keys are closer together. Once you learn to get used to the smaller keyboard size you will find that your fingers don't have as far to travel. Make sure your laptop has space for a 64GB SD card - we'll come to this later.

Another very useful thing to have is a spare battery or a battery charger. There are many exciting types of battery chargers that you can get, and these will generally allow you to charge from the sun or even from tablespoons of water in some cases. At the very least you should make sure that you carry the power cable with you so that you can steel power from wall sockets in coffee shops or on the train. This way you won't be left without your laptop because it ran out of power.

You should also get a 64GB SD card and this will help you to do many things with your laptop. It will increase your storage space first and foremost so that you can save more things, but then it will allow you to take that data with you and communicate with other machines. Library computers, many smart phones and everything else take 64GB SD, so if you copy onto there you can print out your items or share music with friends.

Finally you should get an Android phone with the 2.2 version operating system. Why? Because this has internet tethering which enables you to use your phone as a WiFi hotspot thereby sharing your internet connection with your computer. This way you can check your e-mail, look up information online and generally use your computer as you would at home wherever you are.

The best laptop bags then can store all these items in with a little room for notes or a book. Don't necessarily limit yourself to looking for laptop bags as many smaller shoulder bags and carry cases can serve the same purpose.

Want some advice

Merchant Card Payment If you are looking for advice about getting a PCI-compatible, then you are in good company. The following is based on information which a number of retailers and associated payment card service providers have been telling us over the past few months with respect to the PCI DSS.

Whilst we find there is strong understanding within Tier 1 merchants (6 million transactions per year), these organizations, in common with smaller merchants, are keen to hold off on major spending.Regarding the likely cost of any PCI DSS initiative this is covered in a subsequent article. Given the likely costs of the PCI DSS is that in an article after it has been covered.

There is some good common sense in taking a 'wait and see' strategy. Some good common sense in taking a wait and see strategy 'there. The future of the PCI DSS may well see some changes introduced, but this is actually not a good reason to delay implementation of a serious security strategy now. DSS PCI future may well introduce some changes, but this is actually a good reason for the delay in implementing a security strategy is already serious. The big talking points of the moment include Tokenization and End to End Encryption (aka Point to Point Encryption) and both will have a role to play in the future, but right now there are plenty of good PCI DSS measures that should be implemented. Big talking point at present include: Tokenization and end to end encryption (aka point to point encryption), and both have a role to play in the future, but already many good initiatives that the PCI DSS There should be run.

Furthermore, the entire premise of the PCI DSS is that a wide and diverse range of security measures are required, employing a combination of technological defenses and sound procedural practice. Moreover, the assumption is that the range and diversity of all PCI DSS required security measures, employing a combination of technological and procedural practice is sound.

For instance, Event Log management and File Integrity Monitoring are both essential requirements of the PCI DSS and can often be implemented quickly and for minimal expense while at the same time taking care of around 30% of PCI DSS requirements.You can calculate your own PCI compliance score by using the PCI Security Council's Prioritized Approach Tool spreadsheet, available to download free from the PCI Security Council website. You can score their PCI compliance to the PCI Security Council's approach of using a prioritization tool, available for free download from the Web site to calculate the PCI Security Council.

The PCI Security Standards Council website provides a wealth of information for understanding and navigating the PCI DSS. PCI Security Standards Council Web site provides a wealth of information for understanding and navigating the DSS PCI. User forums such as the LinkedIn PCI DSS Compliance Specialist and vendor blogs and websites are also good sources of free information. Admission to the PCI DSS as an expert user forums and blogs and websites are also good sources of information, the seller is free. Typical estimates suggest as many as 35% of retail, hospitality and entertainment organizations still do not understand compliance requirements. The estimates indicate as many as 35 percent of the retail, hospitality and entertainment can still understand the compliance requirements.

However, understanding the way in which other organizations have dealt with the challenges you are facing is the best way to ensure you approach PCI Compliance with a clear vision of where you are likely to end up in terms of investment and procedural development.procedure is developed. There are a number of cautionary tales in the marketplace to heed, such as a Tier 1 Retailer jumping in feet-first with a logging solution, only to find that they needed to employ a team of eight additional personnel to run and manage the system.system. This actually says more about the need to be careful about how you implement PCI Compliance measures and to go into it with your eyes open rather than the real demands of a good PCI event log management system, but it serves to illustrate how it is easy to get this wrong if you do not get good advice before you begin spending money.it serves to show how easy it is wrong if this is good advice before you start spending money.

Nearly all vendors will provide a free trial of any PCI compliance software solution and you would do well to make sure that where your PCI DSS program requires you to make investments and changes to in-house procedures, make sure you can see the big picture for day to day operation.You can see the big picture of the day to day operations.

Implementation of a PCI log server needn't take very long and the overall process of implementing a syslog server trial will show you what you need to log and how much work will be needed. Implementing a server into your PCI requirements and the very long run the overall process syslog server tried to show you what you need to log in, and how much will be needed.

For instance, Windows Servers will need some form of Windows syslog agent to be installed so that events can be forwarded from the Windows Server to the central PCI log server to be backed up centrally. For example, Windows servers to be installed on a Windows operating syslog server so that events can be sent to a central server PCI Sign in need of support. However, you will also need to implement changes to either the Group Policy or Local Security Policy with respect to audit settings, and also review windows event log settings so that logons, privilege usage, policy changes, object access, creation and changes are all being audited and backed up in accordance with the PCI DSS. However, you also change the Group Policy or local security policy with respect to the audit adjustments are needed, and also check the Windows event log settings so that logons, use up, policy changes, object access, create and modify all the auditing and compliance with PCI DSS is supported.

You'll then need to implement logging for your Unix and Linux hosts, AS/400 and mainframe, together with configuring syslog logging for firewalls, switches and routers. Then enter your hosts you want to run Unix and Linux, AS/400 and mainframe, along with the syslog configuration for firewalls, switches and routers need.

The whole process need not take more than a few hours but as well as showing you how much work is likely to be required to get your estate PCI compliant, you will begin to appreciate the PCI DSS philosophy in requiring not just access controls, preventing access to card holder data, but why active monitoring of changes is vital, coupled with a full, forensic-detail audit trail. The whole process over several hours, but also to show how much work you are likely to be required to own land compatible with PCI, PCI DSS, in philosophy, you will begin to understand not only control access, prevent access to cardholder data, but so is the monitoring of changes is vital, along with a full, forensic audit trail details.

Computer Technology ? Where We've Come From and Where We Are

Computer Technology has come a long way over a short period of time. We'll discuss here a summary of the early stages of computer and how it has developed up to this point.

 

The first programmable digital computer was developed in 1944 by a partnership between IBM and Harvard. This was not however a purely electronic computer. It was constructed from seitches, relays, rotating shafts, and clutches. This machine weighed 5 tons and used 500 miles of wires, stood eight feet tall and was powered by a 5 hp electric motor. The machine ran continuously for 15 years.

Computers continued to evolve over time and by the 1960's, there were large mainframe computers in a great many corporate, government, and educational facilities. These computers were programmed through punch cards or teletype machines. The technology continued to evolve into the 70's.

The first Apple computer was the Apple I and it was introduced as a do it yourself kit in 1976.

This was an early precursor to the modern PC. This became viable with the invention of the microprocessor in the early 70's by Intel.

The first IBM PC ran a 4.77 mHz Intel 8088 microprocessor. It came equipped with 16kb o f RAM which could be expanded to 256K. It also came with one or two floppy drives. This computer had a base selling price of ,565.

This computer was marketed by Sears and Computerland stores. Less than four months after the PC was introduced by IBM, Time Magazine named this computer "Man of the Year".

Then in the early 80's Bill Gates developed MS-DOS and had it installed on the IBM PC's. This was a monumental development and helped to launch Gates as one of the richest men in the world.

The development of the MAC computers evolved from work done at the PARC Research Center in California.

This lead to the development of a graphical interface and ultimately to the introduction of the Macintosh computer in 1983. This was a significant development in computers and helped to set the stage for many other computers to follow.

Then in late 1983, Microsoft launched the introduction of Windows which was a program designed to run on IBM and compatible PC's. This was a graphical user interface type of program and replaced earlier MS DOS operating systems.

This set the stage for many more innovations in computing power as Intel made significant strides in this area as microprocessors became ever more fast powerful and complex. The amount of processing power in modern chips is truly staggering and has enabled tremendous strides in the work with personal computers can perform.

And the advancement of software has been equally impressive. These programs were optimized for the hardware they were written for and has helped to enhance our ability to capitalize on computers and has made the use of computer technology practical for virtually anyone anywhere.

The Impact of Computer Technology in Our Daily Lives

The technology that we have today continuously develops so that it makes our daily living more and more convenient and comfortable each day. And one of the most important contributions of computer technology is the enhanced communication technology that we have today.  Check out the GE Fanuc Series of components for example, for example the 90-30 GE Fanuc is an amazing piece of machinery .

Before, if we liked to send messages to our loved ones overseas, there is no other option but to send them "snail mail" which would take more than three weeks. But today, with the use of different communication devices such as computers and mobile phones, communicating with our loved ones has never been so easy.

With just a press of a button or click of mouse, we can instantaneously send and receive messages to our loved ones with the help of internet – we can even talk to them via video conferencing. We can also send and receive instant messages on our mobile phones which enable us to connect to our friends, families, and relatives wherever and whenever we like.

Another important role of computer technology is that it allows us to have a better understanding of everything such as education. Computers are being used nowadays to teach children easily and conveniently which develops their thinking and creativity skills at the same time.

Computer technology arouses the students' creativity as well as their thinking skills. Computers also help students with learning disabilities to be able to easily understand their lessons.

Also, teachers can use computer technology to improve their teaching skills.

Today, with the use of latest word processing applications, students can improve their spellings because these applications can tell if certain word is misspelled. Also, people who have communication disability such as the Mute and Deaf can easily express their thoughts and feelings with the use of computers.
