• 1960s : Gene Amdahl designed the IBM System/360 series of mainframe (G) computers, the first general-purpose digital computers to use intergrated circuits.
• 1961: Dr. Hopper was instrumental in developing the COBOL (Common Business Oriented Language) programming language.
• 1963 : Ken Olsen, founder of DEC, produced the PDP-I, the first minicomputer (G).
The famous computer scientists during the second generation era were:
John Bardeen
Walter Houser Brattain
William Shockly1. The creation of transistor spark the production of a wave of second generation computer.
2. Transistor was small devices use to transfer electronic signals across a resister.
3. Transistors had many advantages compared to other hardware technology.
Transistor ;
• transistors were smaller than vacuum tubes
• they needed no warm up time
• consumed less energy
• generated much less heat
• faster and more reliable
