Overview of Computer Components

Introduction

• Common terms: RAM, hard drive, processor
• Purpose: Overview of computer components for beginners

Essential Parts of a Desktop Computer

1. Case

   • Houses all components
   • Provides an enclosed space

2. Power Supply

   • Provides electricity to components
   • Located usually at the bottom of the case

3. Motherboard

   • Flat circuit board connecting all components
   • Allows data transfer between parts
   • Considered the most important component

Complex Components

Categories

• Focus on: CPU, RAM, hard drive, graphics card

Definitions

• CPU (Central Processing Unit / Processor)

  • Executes commands, performs calculations
  • Often referred to as the "brain" of the computer

• RAM (Random Access Memory)

  • Temporary storage for quick data access
  • Faster than hard drives, but less capacity

• Hard Drive

  • Permanent storage for data and programs
  • Accessed slower than RAM

• Graphics Card (GPU)

  • Handles rendering images and videos
  • Additional calculations for graphical output

Relationship Between Components

• CPU and RAM

  • CPU pulls data from hard drive to RAM for quick access
  • RAM is where active data is stored for easy retrieval

• Hard Drive vs RAM

  • Hard drive: stores all data (videos, documents, programs)
  • RAM: stores data currently in use for quick access
  • Example: Loading a game level requires transferring data from hard drive to RAM

Summary of Functions

• Case: Physical structure
• Power Supply: Electricity source
• Motherboard: Connection hub
• CPU: Executes processes
• RAM: Quick-access storage
• Hard Drive: Long-term storage
• Graphics Card: Visual output management

Additional Components

• Cooling systems, internal wireless cards (extras)
