Lesson 1.4: Computer Hardware

Hardware refers to the physical parts of a computer that we can see and touch. It includes all the components that make the computer work.

🔧 Main Types of Hardware

1. Central Processing Unit (CPU):

The CPU is the brain of the computer. It processes instructions and controls all activities. It includes:

  • Control Unit (CU): Directs operations inside the system

  • Arithmetic Logic Unit (ALU): Performs calculations and logical operations

2. Input Devices:

Devices used to give data or commands to the computer.
Examples: Keyboard, Mouse, Scanner, Microphone, Webcam, Touchscreen

3. Output Devices:

Devices that show or present the results of processing.
Examples: Monitor, Printer, Speakers, Headphones, Projector

4. Memory and Storage Devices:

  • Primary Memory (RAM):
    Temporary memory used while the computer is working. It is fast but data is lost when power is off.

  • Secondary Storage (Permanent):
    Used to store data and files permanently.
    Examples: Hard Disk Drive (HDD), Solid State Drive (SSD), Pen Drive, Memory Card, CD/DVD

🛠️ Additional Hardware Components

  • Motherboard: Main circuit board that connects all components

  • Power Supply Unit (PSU): Provides electrical power to the system

  • Cabinet/Case: Encloses and protects internal parts

Note: Hardware and software work together to make a computer function. Without hardware, software cannot run.

🔄 Basic Functions of Computer Hardware

Computers perform five key hardware functions:

1. Input:

Giving data or commands using input devices.
Examples: Keyboard, Mouse, Scanner, Microphone, Webcam

2. Processing (CPU):

Processes the input data as per instructions.
CPU = ALU + CU

3. Memory:

Used to store data temporarily or permanently.

  • RAM: Temporary memory

  • ROM: Permanent memory with startup instructions

4. Storage:

Stores data and programs permanently.
Examples: HDD, SSD, Pen Drive, CD/DVD, Memory Card

5. Output:

Displays the result after processing.
Examples: Monitor, Printer, Speakers, Projector
