What is a computer?
A computer is an electronic device that processes data and performs tasks based on instructions. It helps with various activities like typing, calculating, browsing the internet, playing games, and much more.
Structure of a Computer
A computer has two main parts:
- Hardware: The physical parts you can see and touch, like the monitor, keyboard, mouse, and CPU.
- Software: The programs and instructions that tell the computer what to do, like operating systems (Windows, macOS) and applications (browsers, games).
Main Components of a Computer
- Input Devices: Tools like the keyboard, mouse, and scanner that let you give commands or data to the computer.
- Output Devices: Devices like monitors, printers, and speakers that show you the results of the computer’s work.
- Central Processing Unit (CPU): The brain of the computer that processes instructions and performs calculations.
- Memory (RAM): Temporary storage that helps the computer run programs and perform tasks quickly.
- Storage (Hard Drive/SSD): Where all your data and files are saved for the long term.
- Motherboard: The main circuit board that connects all components and allows them to communicate.
- Power Supply Unit (PSU): Provides electricity to all parts of the computer.
These components work together to make the computer a powerful tool for work, learning, and entertainment.
