_______ computers have their applicability in controlling air traffic and radar of national defence.
Answer: D
The answer is Hybrid computers.
A hybrid computer combines analog and digital parts. The analog part handles continuously varying signals, such as radar returns, very fast, and the digital part provides precise calculation, storage and control. That combination suits real-time control tasks, and the textbook examples of hybrid computers are air traffic control, radar and air defence systems, along with patient monitoring in intensive care.
Microcomputers are personal computers, and minicomputers are mid-sized multi-user machines. Supercomputers are the fastest machines, used for huge numerical jobs such as weather forecasting and nuclear simulation, rather than for this real-time signal work.
