Question 47 of 319

The operation of a computer and peripherals attached to it is controlled by

  • A. application
  • B. hardware
  • C. live ware
  • D. system software

Correct Answer: D

Explanation
The correct option is D. system software. Detailed Explanation
  1. Understanding System Software:
  2. System software is a type of software designed to provide a platform for other software. It includes the operating system (OS) and all utility programs that manage computer resources at a low level. The operating system is crucial because it acts as an intermediary between users and the computer hardware.
  3. Examples of system software include Windows, macOS, Linux, and device drivers that help the operating system communicate with hardware peripherals.
  4. Role of System Software:
  5. The primary role of system software is to manage the hardware components of a computer and facilitate the execution of application software. It controls the computer's memory, processes, and all peripheral devices (like printers, scanners, and external drives).
  6. When you turn on your computer, the system software is the first thing that loads. It initializes the hardware and prepares the system for user interaction.
  7. Why Other Options Are Incorrect:
  8. A. Application:
    • Application software refers to programs that perform specific tasks for users, such as word processors, spreadsheets, and games. While applications rely on system software to function, they do not control the operation of the computer or its peripherals. Instead, they operate within the environment provided by the system software.
  9. B. Hardware:
    • Hardware refers to the physical components of a computer system, such as the CPU, RAM, hard drives, and peripherals. While hardware is essential for a computer's operation, it does not control itself. It requires system software to manage its functions and operations.
  10. C. Live ware:
    • "Live ware" is a term sometimes used to refer to the human element in computing, such as users and operators. While humans interact with computers and can influence their operation, they do not control the computer's functions in the same way that system software does. The term is not commonly used in the context of computer operation control.
Summary of Key Points
  • System software is essential for controlling the operation of a computer and its peripherals.
  • It includes the operating system and utility programs that manage hardware resources.
  • Application software performs specific tasks but does not control hardware.
  • Hardware is the physical component that requires system software for operation.
  • Live ware refers to human users and does not control the computer's operation.
Revision Summary
  • System software is crucial for managing computer operations and peripherals.
  • It includes the operating system and device drivers.
  • Application software performs tasks but relies on system software.
  • Hardware needs system software for control and operation.
