Explanation

• An operating system that allows a single user to perform only one task at a time is called a Single-User Single-Tasking Operating System.
• Functions like printing a document, downloading images, etc., can be performed only one at a time. Examples include MS-DOS, Palm OS, etc.
• Advantage:
  • This operating system occupies less space in memory.
• Disadvantage:
  • It can perform only a single task at a time.

Explanation

• Supercomputers were introduced in the 1960s as the world's most advanced computer.
• A supercomputer is a powerful computer that can process a large amount of data and computation very quickly.
• Supercomputers perform immense amounts of mathematical calculations.
• Super Computers are also known as Number Crunching.
• Supercomputers are used for areas related to:
  • Science
  • Engineering
  • Education
  • Defense
  • Aerospace

Explanation

Cache memory acts as a buffer between the CPU (Central Processing Unit) and the main memory (RAM).

It is a small, high-speed memory that stores frequently used data and instructions that the CPU is likely to need next.

This allows the CPU to access the data and instructions it needs quickly, without having to wait for the slower main memory to respond.
