Output device The output unit is used for displaying or printing the process the data in a user readable form a computer can have several output devices attached to it. Some of the common output devices are listed below Monitor Monitor is the most common output device is also called visual display unit, an electronic visual display unit or electronic visual display for computers just like a television monitor also display the output on the screen. The output displayed on the monitor is called soft copy. The most of common types of monitors are given below 1. (CRT) cathode ray tube monitors 2.(LCD) liquid crystal display 1. Cathode ray tube monitors CRT monitors were the most common monitors until flat panel screen became of a double they consist of an electronic gun in this monitors a beam of electrons light up the pixels /phosphor dots which forms the inner coating of the screen. CRT monitors are bulky and occupy a lot of space they are available in various ages like 14 inc

Input De vices: Devices by which we feed data and instructions into a computer are called input devices in the given below some of the input devices are as follows. 1.keyboard The keyboard has many keys to enter data and the instructions also. In the keyboard the keys are market with English letters from A to Z, number 0-9, mathematical signs like addition multiplication division etc., And also the keyboard help punctuation marks that helps to us in typing any data to correctly. The keyboard has also special keys is it has some symbols that helps us to recognise their uses. 2 . The Mouse The mouse has two buttons and a scroll wheel. The most is used for select objects text and draw the pictures on the computer. the The Attacks of the most ticket or double clicked to perform different types of tasks. 3.

The first generation computers The first generation computers used in vacuum tubes the process speed was very low these computers are very large inside and it is difficult to write programs. It is used in the year of 1946 to 1958. The second generation computers The basic characteristics of the second generation computers is as follows . I n second generation computers they used transistors by replacing of vacuum tubes. . It was smaller and faster and also more efficient than the first generation computers. . The second generation computers they contained the features like operating system disk storage etc. . it is cheaper than the first generation computers. . And it will also have computer languages like COBOL common business oriented language and fortran formula translation were used in during the second generation for programming. The second generation computers used 1956 to 1963. Thi r d generation of computers 3rd Generation computer is as following the ch
