Study Notes
Peripheral Devices
- Peripheral devices are external devices connected to a computer to expand its capabilities.
Input Devices
- Input devices enable users to enter data and commands into a computer.
- Examples include keyboards, mice, and scanners.
Keyboard
- A keyboard is a device composed of a panel of keys, used primarily for typing.
Common Terminology
- Input and output devices are often referred to as I/O devices.
Output Devices
- Output devices specialize in conveying information processed by the computer, often through visual or auditory means.
- Examples include monitors, printers, and speakers.
Input/Output Devices
- An input/output device is capable of both sending data to the computer and receiving data from it.
- Common examples include touchscreens and modems.
Main Function of Input Devices
- The primary function of an input device is to capture user data and instructions for processing by the computer.
Data Entry Device
- A keyboard is one of the most commonly used devices for entering data into a computer.
Role of the CPU
- The CPU (Central Processing Unit) manages and processes data received from input devices and sends it to output devices as needed.
Function of I/O Devices
- I/O devices facilitate communication between users and the computer by transmitting data in both directions: from user to computer (input) and from computer to user (output).
