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 ***** 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.

Victoria asked:
CPU? RAM? Do you think they are just letters of the alphabet or something to do with computers? If you guessed they have something to do with a computer, you are correct. Not understanding what these basic computer terms can prevent you from making educated decisions on choosing a notebook or computer. Before you even think about shopping for a notebook or computer, you should understand the basic terms and lingo.
What Is CPU?
A CPU stands for central processing unit, which acts as the brain of the computer. It is important when you look at computers that you purchase one with a name brand CPU with high speed. When you look at CPU brands, you want one with a well known reputation that has been in the market for quite sometime. As for the speed of the CPU, CPU speed is measured in GHz. The higher the GHz the faster your computer will run.
What Is RAM?
RAM is the acronym for random access memory, which keeps computers running fast. The more RAM you have the faster your computer will run. RAM only works and functions when your computer is on because it stores temporary files and runs your programs, operating system, etc. In other words, RAM is similar to a person’s short term memory because it remembers every task you perform until it is turned off. If RAM did not clear itself when you turned off the computer, it will store so much useless data that it will eventually overload and crash. This is why is it important to shut down your computer occasionally since you will clear the RAM. Thus, your computer will run faster.
What Is Hard Drive?
A Hard Drive stores data, which allows you to access important files. The hard drive is the computer’s long term memory. Unlike the RAM, which stores unimportant temporary files, a hard drive stores files that matter to you. Every time you save a word document, pictures, movies, etc, they are stored on your hard drive. The amount of storage the hard drive has is measured in GB, which means the higher the GBs the more information you can store.
Now, you know the basics of computer jargon. You can shop easily for your notebook or computer. The best way of getting computers and notebooks for less is by saving money with free computer coupons, computer discount coupons, computer deals, computer rebates, and computer coupon codes by visiting this link below.
http://www.onlinestorecoupon.com/ShopbyCategory/computercoupons.htm
You can browse through the most popular brand of computers and save money with the latest online computer deals. Since you know the basics, you can easily pick out which computer will fit your needs.

Damien Oh asked:
For a gamer, what can be more fulfilling than to build your own gaming computer? In fact, the only way to get the best out of your computer and maximize your gaming experience is to build it yourself. However, there are tightly kept secrets among computer retailers that they don’t want you to know, because it will affect their profitability to a great extent. This article will reveal the secrets that all gamers need to know.
Secret 1) It is very easy to build your own gaming computer
If everyone knows how easy it is to build a computer, then no one will be buying from the computer retailers. This is why most computer retailers tell you that it is very troublesome and complicated to build your own and it is better off to buy one off the shelf. In actual fact, my 10 years old kid took only 1 hour to figure out how to build a computer. How long do you think you need?
Secret 2) It is much cheaper to build your own gaming computer than to buy one off the shelf
Keep in mind that the main focus of the computer retailer is to make as much profit from you, not how good your gaming experience is. As such, never expect a cheap gaming computer from computer retailers. Occasionally, computer retailers may package their computers in a low price to entice you to buy. The fact is: you will not be getting the quality component that your price is paying. Most of the parts in the computer will not be suitable for gaming usage. It might boost the latest CPU in the market, but the power supply, graphics card, motherboards and memory are parts that get obsolete very fast. If you are patient enough to shop around and source for the parts you want, you can save up to 30 – 50% of what you going to pay at the retail stores.
Secret 3) Off the shelf computers are not upgradeable
Building your own computer allows you to choose the parts that are upgradeable in the future. Off the shelf computers don’t and the retailers are keeping mum about it. Most off the shelf computers are using parts that will grow obsolete in a year or two times and the only choice you have then is to buy another computer from them again.
Secret 4) You don’t need extended warranties and technical support
Your computer retailers will definitely sell you the benefit of having extended warranties and technical support because they know that most of the time, it will not realise and it is a pure profit for them. By buying one, you’re betting that your product will break, that the extended warranty will cover the damage, and that repairing the product would cost more than you paid for the extended warranty. In that case, why bother to buy from them in the first place? When you build your own gaming computer, each part comes with warranty. Even if it spoils, you only have to change the individual part rather than the whole computer. This is much cheaper than what you pay for the extended warranty. In addition, the lifespan of a computer system is generally 3-5 years. By the time your whole computer system is spoilt, it is also time to get a new one because all your computer parts will be obsolete by then.
The only way to get the best out of your computer, be it the cost or the gaming performance, is to build your own gaming computer. Computer retailers are keeping mum about this fact and trying means to entice you to buy from them. If you are serious about gaming, don’t ever let the computer retailers stand in your way of owning your very best gaming computer.

Richard n Williams asked:
Demands are high for computing in industry. Industrial machines have to cope with many hostile elements whilst also providing reliable computing. Traditionally industrial computers have been specific, bespoke machines. These industrial computers tend to run old hardware and versions of software. Whilst this has the advantage of making the machines stable and reliable, the out-dated technology may mean the processes controlled by the machine are not done as efficiently.
These machines are also very expensive, not just to buy but also the maintenance. Industrial computers have to be maintained by service engineer, often forcing shutdown of production lines they also have to be replaced periodically as the hardware and software will eventually become obsolete. All computers eventually fail but an industrial computer enclosure means that over three generations of computers can use the same enclosure.
Industrial PC enclosures are a more efficient, affordable and reliable alternative to these expensive machines. The main benefits of an industrial computer enclosure are:
1. Withstand the same environments as an industrial computer, whether that is dust (including explosive atmospheres), dirt, grime, oil, grease and water (even completely doused). Enclosures are rated using European IP ratings that give a clear indication to the types of environments the enclosure can operate in, for example IP 65 totally protects dust whilst protecting against strong jets of water, (the first digit, 6, represents the dust protection the second digit, 5, the water) while IP 66 offers the same dust protection but the enclosure can be completely immersed in water.
2. Enclosures can also withstand the same shocks, vibrations and tampering as the enclosure can be built from robust materials and the enclosed PC can be fitted snugly and secured with shock absorbing bolts. Enclosures can also be securely locked and bolted to floors or walls to protect against theft.
3. For computing in extreme temperatures, computer enclosures can in fact work to a better standard than industrial machines as the extra cooling and heating units can be replaced if they are not working as efficiently as they should (a sealed industrial computer that is running too hot or cold would need to be replaced or returned for an upgrade).
4. Computer enclosures can enable a PC to run equally as reliable as an industrial computer as the desktop PC housed in the enclosure can be any conventional machine, from a trusted office workhorse to the latest all singing, all dancing off-the shelf PC.
5. A computer housed in an enclosure is also far cheaper than an industrial computer. Apart from the initial outlay for the expensive bespoke industrial computer, enclosures can out live an industrial machine by over a decade as an industrial computer will eventually have an internal failure (as all computers do) or become completely obsolete and will need replacing. However, an enclosure can be reused to house another machine and will in general house three generations of machines.
6. A computer enclosure can house monitors, printers, touch-screens and all manner of computing equipment (including the peripherals such as mouse and keyboard ) or they can be combined with water/dust proof sealed keyboards and mouse.
7. As an enclosure houses a conventional PC, any repairs or upgrades can be carried out in-house in minutes rather than have to wait for an engineer and have to shutdown the production.
8. Enclosures can be manufactured from a range of material including food grade stainless steel.
9. Enclosures can be lockable and secured to walls or floors to prevent theft or tampering.
10. Enclosures allow you to choose which software or hardware to run inside the enclosure rather than suffer out-dated technology.
With the demands of industrial computing so variable and extreme, industrial PC enclosures offer a flexibility that even conventional industrial computers fail to match whilst also offering the same protection and reliability for a fraction of the cost. PC enclosures are ideal for even the most hostile industrial environment and while specialist PCs will always be required for certain tasks the majority of uses for an industrial computer can be achieved using a conventional PC housed in an industrial computer enclosure .

Pc Repair Experts asked:
In today’s world most of the people are having their personal computers. Even in the places like schools, hospitals, hotels, etc. They have their separate systems for teaching and maintaining their respective records. So this shows that the necessity of the personal computers is constantly increasing. Everywhere the manual work is conferred to the machine work. Actually it all happened because of the errors which were generated when the work was done manually.
These errors were then further rectified by the computer which never committed those errors which were generated while keeping the records manually. The era came where the computer became popular in almost every field. Now we can see that each and every person is well aware of the computers. So the computer era got its lay in today’s world.
But the problem comes when this computer creates any hardware or software related problem. People who are completely dependent on the computer for their work are really getting deprived of the PC maintenance quandary. Then the people have to wait for the vendor to come and do the repairing of the system. This really consumes lots of time, which is really wastage of funds and the time both. As every person is not aware of the machine’s stuff whether it would be hardware or the software.
For the repairing related problem previously the last option was the vendor but now it has not remained the difficulty as an online PC repair service is available. You need not to wait now for vendor to come and get your PC repaired. You will need only to do an online complaint related to the occurrence of any hardware or software problem in your PC then as soon as possible your issue will be resolved. Not only are this but as the computers expensive devices so its personal user handles it in a very careful manner. The devices are changing and modifying day by day.

Most of our offices and homes are fast becoming cases or warehouses for spoilt computers. Most of the times, we lack the required technicians to effect repairs or we are simply not advised on what to do when our computers stop working. We may be tempted to rush for new computers. Repairing your computer may save a chunk of your money. Why struggle with computers and technology? There is a service, Tech-pros, which you can consult to see if you computers can be reclaimed.
What do you expect from a computer repair service?
It is very common for most of us to anticipate the scenery prior to meeting the technician; while your computer is with the technician and the aftermath of your computer being repaired. This is because no one wants to get entangled in a mess. It may be wise to consider the following:
Where can you get a good repair service?
This subject can be answered by where there is an availability of quality services and accessories. It is recommended at times to get to the manufacturer of that make, but keep in mind that this can be very expensive. Thanks to technological advancements, there are lots of individuals who can provide proficient services similar to those of and even above manufacturers. For example, service companies like Tech-pros may be operational with veteran, specialized technicians who do not only have the specific information and talents, but will equally undertake to help you get the most out of your asset.
Another thing to consider is how long will it take to repair your computer? Computers can be a vital part of businesses or academic investments. So they should not be left to lie in wait. When such important assets go down, it may be probable for Tech-pros to get you going again. For the most part, this will depend on how talented the technicians are and above all, how reachable are the spare parts. These constitute no problem today with the multiplicity of talented technicians and computer accessories. There exist large stores of original accessories as well as used parts of all assortments. A good computer repair service should not take more than five working days for the most complex type of diagnosis.
When looking for a computer repair service, also consider the repair rating. Do some online and offline shopping. Get information from friends and colleagues. They might have had similar problems and may give you the best advice on finding an appropriate repair service. Thanks to numerous online feedbacks for its past clients, Tech-pros possesses of this quality. It may be wise to give it a try; one does not know.

One of the most important components of your computer is the hard drive which is used as a permanent storage device to store data. The data is stored in a digitally encoded form on magnetic platters. It can be manipulated by using the read-write head which is a small electro-magnetic coil, located very close to the magnetic surface. Hard disk drive along with the media on which actual information is stored comes as the same package. Computer repair Minneapolis provides information on how to repair your hard drive in case of a failure.
There are two basic functions of the hard drive: read and write. These operations are performed by the head which has the ability to reach every sector of the hard disk to sense or record data by discharging electrical impulses. The hard disk platters are constantly and rapidly rotating in order to allow the head to read and write data quickly. Rotational speed of a hard disk is one of its important parameters which can be increased to decrease the access time.
To install the hard drive on the system three interfaces have to be used. The first one is the IDE connector which is to be attached to the motherboard in order to access data from the hard drive. Each IDE connector is designed to support two drives; one primary and the other secondary. The second unit is the power connector which is used to connect the hard drive to the power supply. Normally there are indicators on the hard disk as well as the cables to connect them properly and in the right direction. This is an important step which can be used while troubleshooting in computer repair Minneapolis. The third and the last interface is known as the jumper block. A single jumper is a pair of electrical contact points which can be set to use the hard drive as master or slave. Today, the plug-and-play technology allows us to use preset jumpers.
If you are not being able to access your hard disk properly, the first thing to check is whether the BIOS is detecting your hard drive. BIOS stands for Basic Input/Output System and it stores information on how to operate the basic hardware and software for your system. BIOS setup can be entered seconds after the computer is turned on by pressing a special function key. If the newly installed hard disk is not listed, there might be a hardware problem. Since the hard drive is constantly in motion you can hear the low spinning sound if it is working properly. If there is no sound, your hard disk might not have been installed properly. Check the jumper setting again or see if the cables have been connected properly. If you can hear a sound but it seems like a scraping sound, do not attempt to open the hard disk yourself in order to correct the problem. Instead, take it to a professional and have it checked thoroughly to locate a mechanical problem.
Hardware failures in the form of physical damage to the platters are difficult to correct. In such a situation you might not be able to recover data stored on your hard disk. In case of minor defects, computer repair Minneapolis allows us to recover some of the data by placing the media on a special drive designed for recovering data. If you have important data on your system you should copy it to some other location like a tape drive or a CD to prevent possible data loss in case of hard disk crash. Storing data on several partitions located on the same hard disk will not solve your problem. This is a preventive step which must be taken in order to be on the safe side.
If you are interested in manually repairing your hard disk, you will have to learn some basic debugging. This can be initiated by using an MS-DOS command “debug”. To use it properly you need to have a strong hold on machine language, also known as assembly language or machine code. There are proper instructions written in machine language to delete partitions on a hard disk or perform some other functions.
Before attempting to use computer repair Minneapolis shell commands, remember that not all operating systems are designed to operate in the same manner. Older versions of Windows do not support more than 32GB hard disk. The same is the case with file systems or file allocation tables. A partition which is more than 4GB in size will have to use FAT32 instead of FAT16. In order to repair your hard disk properly or to recover data, you will have to learn how these systems work.
You can also lock or unlock a partition in order to prevent it from losing data or becoming corrupted. In some cases the hard disks come pre-locked and may prevent operations like fdisk and encounter problems when you try to install software or another operating system. Simple lock and unlock DOS commands can be used to take the appropriate action needed to start repairing your hard disk.
Computer repair Minneapolis also allows us to recover lost or deleted data. This can be achieved by trying some basic troubleshooting steps before attempting to use other methods. See if your deleted files are still in the recycle bin. If they are not there, check if you have a backup partition which is kept up-to-date manually. In case you don’t have a backup, either on the same hard disk or on some other medium, then you can use a special software program such as Undelete Plus to recover your deleted files. These types of software are available as freeware on the internet and you can download and install them easily in order to retrieve your accidentally deleted files.

Pc Repair Experts asked:
If you’ve purchased a computer, or are just learning about using email and the internet, you may be faced with the problem of abnormal function of PC or system hanging problem very soon.
Somewhere down the line, there will be problems with your computer (adware, spyware, viruses, good software gone bad, etc,). Obviously, you should use protection software to prevent as much as possible. Internet is one the major source of computer virus. Usually they enter your program through an email, or while you are browsing a website.
When these programs run, usually without you knowing, they can cause all types of problems with your computer. Some viruses can be mildly annoying, slowing down your computer as they use your computer’s resources for another purpose. Others can be very dangerous, collecting your personal information and sending it to another party, or damaging your hard-drive.
Once you realize that you need anti-virus software installed and running on your computer, you’ll have to choose which one to purchase and install. This can be a complicated process, but here are some tips to make it a bit easier.
First, check your computer to see if it came with anti-virus software. Many new computers are shipped with anti-virus programs already to go on them, you just need to turn them on. Check your instruction manual to see if this is the case with your computer.
Check with the vendor. If you purchased your computer from a local retailer, check with them to see what anti-virus program they recommend.
I think that the best way to cure virus/worm problems is to prevent them from happening, and the best way to prevent them from hapenning is through education and awareness. Being a geek, understanding viruses seems to come naturally to me, so I figured I would share information about them with others.
If you are new to computers, please take some time and seek out professional assistance — the rest of the Internet will thank you for it.
Here’s some general tips for staying safe online:
Download and install the Firefox web browser and use it exclusively instead of Internet Explorer. IE is chock full of security holes, and new ones are being found all the time. Using IE is a big liability these days.
