Computer Software Basics

1. What is Computer Software?

Software is a set of instructions or programs that tell a computer what to do. It is the non-physical part of a computer system (unlike hardware, which you can touch).

2. Types of Software:

A. System Software

Helps run the computer hardware and system.

Operating System (OS) – Manages hardware and software (e.g., Windows, macOS, Linux).

Utility Programs – Tools for maintenance (e.g., antivirus, disk cleanup).

Device Drivers – Help the OS communicate with hardware.

B. Application Software

Designed for end users to perform tasks.

Examples: Microsoft Word, Excel, web browsers, games, media players.

C. Programming Software

Used by developers to write code.

Examples: Compilers, text editors (like VS Code), debuggers.

3. Software Installation and Execution

Installation: Process of setting up software on a computer.

Execution: Running the software to perform tasks.

4. Software Updates

Software needs updates for:

Security patches

Bug fixes

New features or improvements

5. Licenses and Types

Freeware: Free to use (e.g., VLC Media Player)

Shareware: Free trial, pay to continue

Open-source: Free and editable (e.g., Linux)

Computer Hardware Basics

1. What is Computer Hardware?

Computer hardware refers to the physical components of a computer system—the parts you can touch.

2. Key Hardware Components:

a. Central Processing Unit (CPU)

The "brain" of the computer.

Executes instructions and processes data.

Speed is measured in GHz (gigahertz).

b. Motherboard

The main circuit board.

Connects all components: CPU, RAM, storage, etc.

c. Random Access Memory (RAM)

Temporary memory for active processes.

More RAM = better multitasking.

d. Storage Devices

HDD (Hard Disk Drive): Slower, mechanical storage.

SSD (Solid State Drive): Faster, no moving parts.

e. Power Supply Unit (PSU)

Converts electricity to usable power for components.

f. Graphics Processing Unit (GPU)

Renders images, videos, and animations.

Important for gaming, design, and AI tasks.

g. Input Devices

Devices you use to give input to a computer.

Example: Keyboard, Mouse, Scanner, Webcam.

h. Output Devices

Devices that receive information from the computer.

Example: Monitor, Printer, Speakers.

i. Cooling System

Keeps components from overheating.

Example: Fans, Heat sinks, Liquid cooling.

3. Optional Components

Optical Drives: For reading/writing CDs/DVDs (less common now).

Expansion Cards: Add extra functions like sound or network cards.
