Introduction to Computers

• Computers are electronic devices that can store, process, and retrieve information.
• They use software (programs) to perform tasks.
• Hardware refers to the physical parts of the computer.
• Software enables the hardware to perform tasks.

Basic Computer Hardware

• Input devices: Allow you to enter data into the computer. Examples include keyboards, mice, and touchscreens.
• Output devices: Show the results of the computer's processing. Examples include monitors, printers, and speakers.
• Central Processing Unit (CPU): The "brain" of the computer, responsible for processing instructions.
• Memory (RAM): Stores data and instructions currently in use by the computer.
• Storage devices (e.g., hard drives, SSDs, flash drives): Store data for long-term use.

Basic Input Devices

• Keyboard: Used to type text and commands.
• Mouse: Used to select items, navigate menus, and control the computer's pointer.
• Touchscreen: Allows users to interact with the computer by touching the screen.

Basic Output Devices
