Key facts from Computers, Information and Communication Technology

  • First-generation computers used vacuum tubes; the second generation moved to transistors.
  • Analog computers work on continuous variable data rather than discrete binary data.
  • The Control Unit directs and coordinates the operations of the CPU.
  • Cache memory gives the fastest access to the CPU; the hierarchy from fastest to slowest is registers, cache, RAM and magnetic disk.
  • Adding more RAM to a system with many page faults reduces its dependence on virtual memory.
  • An SSD differs from an HDD by the use of NAND flash memory.

Frequently asked questions

How many RAS Prelims practice MCQs are there on Computers, Information and Communication Technology?

This page has 200 practice MCQs on Computers, Information and Communication Technology (Science and Technology). Each has the correct answer, and most have an explanation.

What was used in first-generation computers?

Vacuum tubes. They were large, used much power and produced heat. The second generation replaced them with transistors, which were smaller, faster and more reliable, and later generations moved to integrated circuits and microprocessors.

Which memory is fastest for the CPU?

Cache memory, apart from the registers inside the CPU. The memory hierarchy from fastest to slowest is registers, cache, RAM and magnetic disk, and capacity increases as speed falls.

How does an SSD differ from an HDD?

An SSD stores data in NAND flash memory with no moving parts, while a hard disk drive uses spinning magnetic platters. As a result an SSD is faster, quieter and more resistant to shock.
