2. Computer Hardware
Output Devices are responsible for outputting information from the computer. Some examples of output devices are monitors, printers, projectors, sound cards, video cards and speakers.
What is hardware?
Computer hardware are all the components that you can see and touch, so all physical parts and devices of the computer.
Types of hardware:
- Processing Devices: The central processing unit (CPU) is also known as the brain of the computer and performs all types of data processing operations.
- Input devices are responsible for sending signals or data to the CPU. They are generally used for interacting or communicating with the computer. Some examples of input devices are keyboards, mice, joysticks, microphones, webcams, and scanners.
Microphone - Webcam - Joystick
- Output Devices are responsible for outputting information from the computer. Some examples of output devices are monitors, printers, projectors, sound cards, video cards and speakers.
Projector - Speaker
- Input/Output Devices have elements of both, input and output devices. They accept inputted data and are capable of outputting information in return. Examples include modems and digital cameras.
Modem - Digital Camera
- Storage Devices are designed to store information for longer periods of time. Information can be shared by connecting them to the computer either internally or externally and then saving information on them.
