Purpose Of Lesson Part 1

Hardware and the 5 basic hardware

components required to have a working

Personal Computer (PC).

5 BASIC COMPONENTS• HARDWARE: CPU, MONITOR,

KEYBOARD, MOUSE, SPEAKERS, MICROPHONE, COMPONENTS OF THE CPU, & ETC.

1. CENTRAL PROCESSING UNIT (CPU)

2. MOTHERBOARD

3. RANDOM ACCESS MEMORY (RAM) MEMORY CARDS

4. THE POWER SUPPLY

5. SYSTEM HARD DRIVE

HARDWARE• IS THE HARD

PARTS OF THE COMPUTER THAT COULD BE HELD IN YOUR HAND!

CENTRAL PROCESSING UNIT (CPU)

• IS THE COMPUTERS MAIN BRAIN THAT DOES CALCULATIONS AND RUNS ALL THE OTHER PARTS OF THE COMPUTER.

MOTHERBOARD

• IS THE WIRING OF THE COMPUTER LIKE THE HUMAN NERVOUS SYSTEM

more files

• HD’s available up to 10 Terra Byte (TB)

• 10TB = 10,000 Gigabytes

• How BIG is that 14,285 720p movies
