Computer and Its Components

A computer is a complex electronic device that processes data to perform various tasks. It consists of several interconnected components that work together to execute instructions and store, retrieve, and process data. Here are the main components of a typical computer system:

  1. Central Processing Unit (CPU):
    • Often referred to as the brain of the computer, the CPU is responsible for executing instructions of a computer program. It performs arithmetic and logical operations and manages data movement to and from other components.
  2. Memory (RAM – Random Access Memory):
    • RAM is volatile memory used by the CPU to store and quickly retrieve data that is actively being used or processed. It is temporary storage and loses its contents when the power is turned off.
  3. Storage Devices:
    • These devices are used for long-term data storage. Common types include:
      • Hard Disk Drives (HDD): Magnetic storage devices with large capacities for storing data.
      • Solid State Drives (SSD): Faster and more durable than HDDs, using flash memory for storage.
      • Optical Drives: Such as CD, DVD, or Blu-ray drives for reading and writing optical discs.
  4. Motherboard:
    • The motherboard is the main circuit board that houses the CPU, memory, and other essential components. It provides the communication pathways between the different hardware components.
  5. Power Supply Unit (PSU):
