Features of Second Generation Computer
Made up of transistors.
Magnetic tapes were used to store data.
Small in size and less expensive than the first generation
computer.
Faster and reliable.
Transistor
Third Generation (1960s)
In the third generation, the invention of Integrated
Circuits (IC) led to smaller-sized computers with
better functioning and more storage. They were
smaller, cheaper, and more efficient than the
previous two generations, and were sometimes called
Integrated Circuits
minicomputers.
Features of Third Generation Computer
These computers were made of ICs.
The use of the ICs reduced the size and increased the speed of
the computers.
They were more affordable and dependable.
Fourth Generation (1970s)
In the 1970s, Very Large Scale
Integration (VLSI) came into existence
in which thousands of transistors
were placed on a single chip called a
microprocessor. They were sometimes
Microprocessor
called microcomputers.
IBM released their first line of desktop
PC, which used Intel 8088 chip as CPU.
In 1983, IBM introduced the PC-XT, IBM PC
which had more memory and more hard drive space.
In 1985, Microsoft released the first version of Microsoft Windows.
