Third Generation Computers

Comparing to first generation and second generation computers, third generation computer size is small. These generation computers are made with semi conductors and integrated circuits. The semiconductors are made with the insulator and a conductor. Third generation computers contains operating system. The main use of operating system is it executes more than one programs in a single time. The IBM was developed IBM 360 in the year 1964 and it’s introduced in the year 1965. The IBM 360 contains 6 computers like one family and peripherals. These six computers are worked together to execute the program. These computers are used transistors but later its used integrated circuits. The PDP-8 was the first successful computers made with the integrated circuits. The PDP-8 was introduced in the year 1965. In 1965 the cost of this computer is $20,000 later the cost is reduced.
