Generations of Computers: Transistors (1956-1963)

Transistors

            -Smaller
            -From Magnetic Drum to Magnetic Core
            -Faster
            -Cheaper
            -More Energy-efficient
            -More Reliable
            -Still generated great deal of heat
            -Punch Cards for Input

            -Print-outs for Output

            -Used symbolic/assembly languages

            -Overheating still causes damage to computer
            

Examples:

1.     COBOL

2.     FORTRAN

*Stored their instructions in their memory.
*Developed for atomic energy industry.
