Question

Which of these generation computers used integrated circuits in their CPUs for the first time?
1. First generation
2. Third generation
3. Fourth generation
4. Second generation

Answer 1

Correct Answer - Option 2 : Third generation

The correct answer is Third generation. 

Third Generation (1964-1977):

• This generation was introduced by the development of integrated circuits  
• These Integrated Circuits (IC)s are popularly known as Chips.
• So it is quite obvious that the size of the computer got further reduced
• e.g IBM-360, ICL-1900, IBM-370, and VAX-750
• Higher-level language such as BASIC (Beginners All-purpose Symbolic Instruction Code) was developed during this period

Generation	Duration	Electronic Component Used
First Generation Computers	1946 - 1954	Vacuum Tubes
Second Generation Computer	1955 - 1964	Transistors
Third Generation Computer	1964 - 1977	Integrated Circuits
Fourth Generation Computer	1978 - Present	VLSI or Microprocessors
Fifth Generation Computer	Present and Future	ULSI or Bio-Chips
