1. 3 rd Generation of Computer (1965-1971)

2. Content What is computer? 3 rd generation of computer Main technology of 3 rd generation computer Input devices of 3 rd generation computer Output devices of 3 rd generation computer Advantages & disadvantages of 3 rd generation computer

3. What is computer? A computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations automatically.

4. 3 rd generation of computer Third generation of computers were computers that emerged due to the development of the integrated circuit(IC).They were the first steps toward computers as we know today.

5. Main technology of 3 rd generation computer Hardware Technology The third generation computers used the Integrated Circuit (IC) chips . In an IC chip, multiple transistors are placed on a silicon chip . Silicon is a type of semiconductor. The use of IC chip increased the speed and the efficiency of computer, manifold. The keyboard and monitor were used to interact with the third generation computer, instead of the punched card and printouts .

6. Integrated Circuits (IC)

7. Software Technology The keyboard and the monitor were interfaced through the operating system. Operating system allowed different applications to run at the same time. High-level languages were used extensively for programming, instead of machine language and assembly language.

8. Computing Characteristics The size of these computers was quite small compared to the second generation computers. The computation time was in nanoseconds. Physical Appearance
