Horses Computer viruses are man-made program or a piece of code which can load onto your computer without your knowledge and cause damage to your computer system. The dangerous part of the computer viruses is they are attached to a file or program‚ which means the computer viruses will not running until you click the file or program‚ and even more dangerous type of viruses is one capable of transmitting itself across networks and bypassing security system. Worms are similar to computer viruses

What is a computer: A computer is an electronic device that executes the instructions in a program. A device that accepts data‚ processes the data in accordance with the stored program‚ generates results and usually consists of input‚ output‚ storage‚ Airthmatic logic and control units. A computer has four functions: a. accepts data Input: Data or information written into the computer by user The Information Processing Cycle b.processes data Processing: The calculations performed according

Game machines are special computers that work by sending imagines to the screen and responding to the buttons you press. Computers have existed for many years helping people keep track of information and solving problems. The development of the computer started with the need to keep track of

Computer Hardware came about when machines needed separate manual actions to be able to perform specific mathematical functions. Luckily in 1941‚ a man by the name of Konrad Zuse invented what was considered the first working‚ fully operable computer. Prior to this‚ most of the calculations were done manually to calculate by people with adding machines. Today these adding machines are better known as calculators. Back then‚ all you had to do is push buttons‚ but in today’s modern software technology

Computer hacking is the practice of modifying computer hardware and software to accomplish a goal outside of the creator’s original purpose. People who engage in computer hacking activities are often called hackers. Since the word “hack” has long been used to describe someone who is incompetent at his/her profession‚ some hackers claim this term is offensive and fails to give appropriate recognition to their skills.

Due to the fact that more then half of the American population owns computers‚ computer ethics are a growing concern in a rapidly changing society. Computer ethics can be broken down in to many topics including piracy‚ hacking‚ viruses

Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis‚ understanding‚ thinking‚ and generically solving such problems resulting in an algorithm‚ verification of requirements of the algorithm including its correctness and its resource consumption‚ implementation (commonly referred to as coding[1][2]) of the algorithm in a target programming language.
