Hardware and Software
Delhi Police Exam
1. What is Hardware?
Hardware refers to the physical parts of a computer system — the components that you can see and touch. They form the body of the computer and help in processing data.
Physical & Tangible Components
Can be Seen and Touched
Forms Body of Computer
Helps in Processing Data
Simple Definition: Hardware is the collection of tangible components of a computer that perform operations and store data.
Types of Hardware
Examples of Hardware
Keyboard
Mouse
Monitor
Printer
CPU
RAM
Hard Disk
Motherboard
Hardware Categories
| Category | Description | Examples |
|---|---|---|
| Input Devices | Used to enter data | Keyboard, Mouse, Scanner |
| Processing Devices | Perform operations | CPU (ALU + CU + Registers) |
| Storage Devices | Store data permanently or temporarily | Hard Disk, Pen Drive, RAM |
| Output Devices | Display results | Monitor, Printer, Speaker |
| Communication Devices | Help in data transfer | Modem, Router, Wi-Fi Adapter |
2. What is Software?
Software is a set of programs, instructions, and data that tells the hardware what to do. It forms the intelligence or brain of the computer.
Set of Programs & Instructions
Non-Physical & Intangible
Forms Intelligence of Computer
Tells Hardware What to Do
Simple Definition: Software is a collection of programs that enables a computer to perform specific tasks.
Types of Software
Examples of Software
MS Word
Excel
Windows
Linux
Chrome
Photoshop
VLC Player
Android
Software Categories
| Type | Description | Examples |
|---|---|---|
| System Software | Controls hardware and runs the system | Windows, Linux, macOS |
| Application Software | Performs specific user tasks | MS Office, Browsers, Games |
| Utility Software | Helps in maintenance and protection | Antivirus, File Manager, WinZip |
3. Difference Between Hardware and Software
| Basis | Hardware | Software |
|---|---|---|
| Nature | Physical & tangible | Non-physical & intangible |
| Function | Executes operations | Provides instructions |
| Failure | Can wear out or damage | Corrupts or crashes |
| Development | Made of electronic components | Written using programming languages |
| Examples | CPU, Keyboard, Monitor | Windows, Word, Photoshop |
4. Real-Life Analogy
Think of a computer like a human body:
Hardware
→ Body parts
(eyes, hands, brain hardware)
Software
→ Mind & instructions
(how to use the body)
Without software, hardware is just a dead machine; without hardware, software can't function.
5. Common Delhi Police / SSC Exam Facts
Hardware = Physical part; Software = Set of instructions
MS Word, Excel → Application Software
Windows, Linux → System Software
Antivirus → Utility Software
CPU → Hardware, not software
Software needs hardware to function
6. Quick Recap
| Concept | Summary |
|---|---|
| Hardware | Tangible components like CPU, Monitor, Keyboard |
