Answer:
1) Super computer-A supercomputer is a computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).
2)Printer-A printer is a hardware output device that is used to generate hard copy and print any document. A document can be of any type such as a text file, image, or the combination of both. It accepts input command by users on a computer or on other devices to print the documents.

3)MICR-MICR technique works by passing a physical document such as a cheque containing magnetic ink that needs to be read with a machine that can magnetize the ink on that document and then translate its magnetic information into characters. ... The laser printer used for MICR accepts Magnetic Ink and Character Recognition toner.
4)4th generation computers-The period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. ... As a result, it gave rise to Personal Computer (PC) revolution. In this generation, time sharing, real time networks, distributed operating system were used.
5) Operating systems-An operating system is a software programme required to manage and operate a computing device like smartphones, tablets, computers, supercomputers, web servers, cars, network towers, smartwatches, etc. ... Moreover, the operating system manages the software side of a computer and controls programs execution.
