Which of the following IC was used in third generation of computers?
SSI and MSI IC was used in third generation of computers.
SSI, MSI, The first integrated circuits contained only a few transistors and so were called “Small-Scale Integration (SSI). They used circuits containing transistors numbering in the tens. They were very crucial in development of early computers.
The next step in the development of integrated circuits, taken in the late 1960s, introduced devices which contained hundreds of transistors on each chip, called "medium-scale integration" (MSI).
An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors.
