Main Components of Computer System

Visual Description of Slide Presentation

• The presentation slide has a blue screen background with a green light effect.
• The slide is titled "Main Components of Computer System".

Computer System Components

• The most important component of a computer system is debated, but each component plays a crucial role.

RAM vs ROM

• RAM (Random Access Memory) is a volatile memory that loses data when the power is turned off.
• ROM (Read-Only Memory) is a non-volatile memory that retains data even when the power is turned off.

Main Components of Computer System

• The main components of a computer system include:
  • Input devices
  • Central Processing Unit (CPU)
  • Output devices
  • Backing storage
  • Internal memory

Backing Storage

• Backing storage refers to a type of memory that provides long-term storage for data and programs.

Input and Output Devices

• Input devices: Examples include keyboard, mouse, scanner, and microphone.
• Output devices: Examples include monitor, printer, and speaker.

Input vs Output Devices

• Input devices: Receive data from the user or external sources (e.g., keyboard, mouse, scanner).
• Output devices: Display or present data to the user (e.g., monitor, printer, speaker).

Internal Memory vs Backing Storage

• Internal memory: Temporary storage for data and programs while they are being processed (e.g., RAM).
• Backing storage: Long-term storage for data and programs when not in use (e.g., hard drive, solid-state drive).
