A workstation is like a personal computer, but it has a more powerful microprocessor and, in general, a higher-quality monitor. • Minicomputer: A multi-user computer capable of supporting up to hundreds of users simultaneously. • Mainframe: A powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously. • Supercomputer: An extremely fast computer that can perform hundreds of millions of instructions per second.

  3. five components of a computer. • hard drive, motherboard, RAM, CPU and power supply.

  4. Explain the difference between system software and application software. • System software is a software that deals directly with the architecture of the computer hardware. Operating system is a system software.Application software is a software that interacts with end users and basically does whatever end user is working on.
