Introduction

Basic Components of a Computer:

  1. Hardware – The physical components of a computer, including:

    • Central Processing Unit (CPU) – The brain of the computer that executes instructions.
    • Memory (RAM) – Temporary storage for active tasks and processes.
    • Storage (HDD/SSD) – Permanent storage for data and software.
    • Input Devices – Devices like keyboards, mice, and touchscreens that allow user interaction.
    • Output Devices – Devices like monitors, speakers, and printers that display results.
       

  2. Software – The programs and operating systems that control hardware and allow users to perform tasks.

    • System Software – Includes operating systems (e.g., Windows, macOS, Linux) that manage computer resources.
    • Application Software – Programs designed for specific tasks (e.g., Microsoft Word, web browsers, games).

Explanation

Functions of a Computer:

  • Input – Receiving data from external sources.
  • Processing – Performing calculations and logic operations.
  • Storage – Saving data for short-term (RAM) or long-term use (HDD/SSD).
  • Output – Displaying or transmitting processed information.
  • Networking – Communicating with other computers via the internet or local networks.
