A computer is an electronic device that processes data into useful information by following programmed instructions. Early mathematicians in the 17th century tried to build machines for basic math functions. In 1804, Charles Babbage designed the difference engine, which had a mechanical memory. Computers have since progressed through generations based on technological advancements - from vacuum tubes to transistors to integrated circuits and microprocessors - making them smaller, faster, and more efficient. Today, supercomputers are the most powerful for complex tasks, mainframes are for large organizations, and personal computers are most common.

- 2. WHAT IS COMPUTER In basic term, a computer is an electronic device that processes data, converting it into information that is useful to people. Any computer- regardless of its type- is controlled by programmed instructions, which gives the machine a purpose and tell it what to do.
- 3. Asearly as the seventeenth century, mathematicians were trying to create a machine that could perform basic mathematical functions such as, addition, subtraction, division and multiplication.
- 4. 1804 British inventor, Charles Babbage, designed an all-purpose problem-solving machine, the difference engine, which had a mechanical memory to store the results of calculations.
- 5. Second Generation - 1956-1963: Transistors Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 50s. *smaller,faster and cheaper.
- 6. Third Generation - 1964-1971: Integrated Circuits The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
- 7. Fourth Generation - 1971-Present: Microprocessors The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip.
- 8. Fifth Generation of Computer Personal computers Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today.
- 10. Supercomputers are the most powerful computers made. Supercomputers are used to process huge amount of data for complex processes such as nuclear fission.
- 11. Mainframe computers are the largest among the computers in use today. Mainframe computers are used where many people in large organizations are frequently accessing similar information.
- 13. Personal Computers are the most common computers in use today. A personal computer can be a desktop computer, a notebook or a laptop or a Personal Digital Assistant.
