Study Notes

Computer Hardware and Components

  • The output device is responsible for sending information back to the user on a PC.

Computer Memory

  • PC memory is measured in terms of capacity, typically in bytes (e.g., kilobytes, megabytes, gigabytes).

Computer Generations

  • A major development in 4th generation computers was the introduction of microprocessors.

Networking

  • The purpose of a LAN (Local Area Network) is to connect computers and devices in a limited geographical area for communication and resource sharing.

Computer Performance

  • The factor that significantly impacts a computer's performance is the capacity of its components, including the processor, memory, and storage.

Computer System Components

  • The three main components of a computer system are the input device, processing unit, and output device.

Computer Terminology

  • The term "hardware" is used to refer to the equipment associated with a computer system.

Computer History

  • The 1st generation of computers used vacuum tubes for circuitry and magnetic drums for memory.
  • In the 2nd generation of computers, vacuum tubes were replaced with transistors.
  • The 2nd generation of computers used high-level programming languages, such as assembly languages and COBOL.

This quiz covers the basic concepts of Information Technology (IT) including the components of a computer system, the definition of a computer, and the characteristics of the first generation of computers.
