computer can simply mean a machine that calculated. Let’s take a look at the past and find out who the freaks who were around with a device costing just tasks by recognizing inputs and outputs, could carry out the corresponding. Abacus developed in 3000 BC may be the first computer, as it was a simple counting device. In 1941 a German engineer Konard Zuse developed a first programmable calculator using binary math and Boolean logic. UNIVAC was developed in 1951 and the real breakthrough came in 1952 when Texas Instrument developed the integrated circuit. In 1964, IBM mainframe computer called IBM 360. Apple Apple I and Apple II in 1976 in 1977. The computer, which was most of us in terms of look and functionality in 1981, when IBM introduced the Personal Computer unveiled. The main features of a computer are: 1 – It follows and is capable of following a specific set of instructions. Run 2 – The preset list of instructions usually can be used as a computer program known. The basic components that are essential to make a computer: 1 – input device, consisting of a keyboard and mouse that are used for entering instructions and data entered into the computer. see 2 – output device such as the screen or the screen, printer etc, which enables us what did the computer. 3 – The Central Processing Unit, which as the brain of the computer where all the processing is performed, the data and instructions are executed, well known. 4 – The memory is the powerhouse of the computer stores data and instructions in it. 5 – Mass Storage Devices are those which permanently stores and retain large amount of data. The most common floppy disk drives, CD-ROMs, hard drives, etc. Computers come in different types for different purposes, taking into account different categories designed by its users. According to their type have different abilities and are priced accordingly. The most popular computer is the personal computer, which is for the personal use of a single user at a time. They come in two types, a desktop and a laptop. Then there is a still smaller palmtop computer as that can be held in the palm of the user known. While these are the smaller and personal types of computers, the mainframe, workstation and supercomputer, the major high-end computers are used by large organizations. Computers can perform a wide range of functions such as word processing, digital audio / video composition, Internet, communications and networking, and desktop publishing. Computers word processing capability includes automatic correction of spelling and grammatical errors. Internet is one of the greatest inventions of man. It combines an infinite number of computers in the form of a web. Ungodly amounts of information are available free on the Internet and communication facilities are available such as messaging, audio and video conferencing available. Graphic engineers are using computers for editing audio and video compositions. No media can be completed without the help of the production of computers. Nowadays, computers are essential for banks, train and plane reservations, Education and even defense of a country. There is virtually no area of the economy that does not use computer. Important and critical business functions can not be done without the help of computers. Just like human beings and computers are vulnerable to diseases that are created by the attack of viruses. The correct backup of all data stored in computer must be maintained in order to provide backup in case of media failure. Computer must be protected by passwords from unauthorized use and must be protected from viruses in them by installing anti-virus programs. Computers, when used properly backed up and can do wonders for the human species to create and the results can not be achieved without producing them.
