Correct Answer : Option (C) : MSI
Explanation : The terminologies like MSI, SSI, LSI and VLSI came out from the complexity of the integrated circuit. It means the total number of transistors are fabricated on a single chip. Jack Kilby invented the first integrated circuit in 1959, so, after that, the Integrated circuit has emerged like SSI, LSI, MSI and VLSI.
In MSI (Medium Scale Integration) = 30 - 300 gates /chip (counters, multiplexers, registers)
In LSI (Large Scale Integration) = 300 - 3000 gates /chip (8-bit processors)
In SSI (Small-Scale Integration) = 3 - 30 gates /chip (logic gates, flip flops)
In VLSI (Very Large-Scale Integration) = >3000 gates / chip (16 bit and 32- bit processors)
