The document provides a simplified block diagram of a typical computer, outlining the major components and their interconnections. The components include the central processing unit (CPU) for controlling instructions, memory for temporary and permanent storage, input devices like keyboards for entering data, and output devices like monitors for displaying information. Other components are storage devices like hard drives, the motherboard for connecting components, a power supply, and peripheral devices.

1. Block Diagram of a Computer

2. A block diagram of a computer typically illustrates the major components and
their interconnections. Here's a simplified block diagram of a computer:
Central Processing Unit (CPU)
• Controls and executes instructions.
• Arithmetic and logic operations.
Memory
• RAM (Random Access Memory) for temporary data storage.
• ROM (Read-Only Memory) for permanent data storage.
Input Devices
• Keyboard, mouse, touchpad, etc.
• Convert input into machine-readable data.
Output Devices
• Monitor, printer, speakers, etc.
• Display or provide output to the user.

3. Storage
• Hard Drive (HDD) or Solid State Drive (SSD) for permanent data storage.
Motherboard
• Main circuit board connecting all components.
• Houses CPU, memory, and facilitates data transfer.
Power Supply
• Provides electrical power to all components.
Peripheral Devices
• Additional devices like printers, scanners, external drives, etc.
Bus System
• Data highways connecting various components for communication.
Graphics Processing Unit (GPU)
• Handles graphics-related operations and rendering.

4. Network Interface Card (NIC)
Allows communication with other computers over a network.
System Software
Operating System (OS) for managing hardware and software.
Application Software
Programs and applications used for specific tasks (e.g., word processing, web
browsing).
This is a high-level and simplified block diagram, and real-world computer systems can
have more complex and detailed architectures based on the specific purpose and
configuration of the computer.
