2.1. 2nd Generation Computer

2nd Generation Computer

Characteristics of 2nd Generation Computers

1.      They used transistors for internal operations. Transistors replaced the vacuum tubes in the 1st generation computers

2.      Magnetic core memory replaced the magnetic scrums as memory. Increase in main primary memory storage capacity up to 22 kilobytes of ram memory.

3.      They were faster in input and output process

4.      High level programming language e.g. COBOL (common business oriented language), FORTRAN (formula translator)

5.      Introduction of super computers eg liver more automatic research computer (LABC) and IBM 7030

6.      Magnetic tapes and disks replaced punch cards for exterior storage.

7.      Computer became less expensive.

8.      They generated less heat.

9.      They had increased speed and reliability.
