5 Computer Basics: Inside a Computer

Chapter 1: Introduction

• Overview of computer components and their functions

• Importance of understanding the parts that make a computer work

Chapter 2: Motherboard

• Definition: A large circuit board critical to the operation of a computer

• Key components included:

  • CPU (Central Processing Unit): Often described as the brain of the computer

Chapter 3: CPU (Central Processing Unit)

• Functionality: Processes information and executes commands

• Significance in computer operations

Chapter 4: Heatsink

• Purpose: Designed to manage heat generated by the CPU

• Material: Typically made of metal to effectively draw heat away from the processor

• Also contains RAM (Random Access Memory)

Chapter 5: RAM (Random Access Memory)

• Function: Acts as the short-term memory used during computations

• Limitation: Data in RAM is cleared when the computer powers off; cannot store files long-term

• Hard Drive: Provides long-term data storage

  • Traditional hard drives use magnetic platters for data storage

  • Newer computers often utilize Solid-State Drives (SSDs): Faster, more durable but more expensive

• Expansion Slots: Featured on many desktop motherboards for upgrades with expansion cards

Chapter 6: Hard Drive

• Function: Long-term storage device that retains data when the computer is off

• Types of hard drives:

  • Magnetic Platter Hard Drives: Use magnetic storage methods

  • Solid-State Drives (SSDs): Modern alternative, faster and more reliable

• Importance of upgrading with expansion cards, such as video or wireless cards

Chapter 7: Expansion Slots

• Purpose: Allow installation of additional hardware to enhance computer performance

• Common uses for expansion cards:

  • Video cards for improved graphics

  • Wireless cards for internet connectivity

• Limitation: Most laptops do not have expansion slots

Chapter 8: Power Supply Unit

• Function: Supplies power from the wall outlet to all computer components

• Essential for enabling all parts of a computer to operate

• Laptops include built-in batteries allowing for portable use

Conclusion

• Summary of the components that make up a computer

• Understanding the internal workings contributes to a demystified view of computers
