Hardware and software are the two fundamental parts of a computer system.
Hardware refers to the physical components of a computer that can be seen and touched, while software refers to the programs and instructions that tell the hardware what to do.
In simple words:
Hardware = Physical parts of a computer
Software = Programs and instructions
For example, a keyboard is hardware because it is a physical device, while Microsoft Word is software because it is a program used to create and edit documents.
A computer needs both hardware and software to perform useful tasks.
What is Computer Hardware?
Computer hardware refers to the physical components that make up a computer system.
Hardware includes all the electronic, electrical, and mechanical components that can physically exist.
Common examples of hardware include:
- CPU
- Motherboard
- RAM
- SSD
- HDD
- Keyboard
- Mouse
- Monitor
- Printer
- Graphics Card
- Speakers
- Network Card
Simple Example of Hardware
Suppose you type your name using a keyboard.
The keyboard is a physical device that sends input to the computer.
Therefore:
Keyboard = Hardware
The monitor that displays your name is also hardware.
What is Computer Software?
Computer software is a collection of programs, instructions, and related data that tells computer hardware how to perform different tasks.
Software allows users to perform activities such as:
- Creating documents
- Browsing websites
