Content
The computer hardware:
Computer hardware refers to the physical parts of a computer system. This includes
- The input devices
- output devices,
- storage devices,
- arithmetic and logic units,
- and control units.
The input devices
These devices are used to send input, instructions, and data to the computer system.
Input devices are used to input data or instructions into a computer. Common input devices include
- keyboards,
- mice,
- trackballs,
- touchpads,
- Scanners
- digital cameras,
- and joysticks.
The output devices
These devices display instructions and output in a user-friendly mode or manner. Output devices are used to output data or instructions from a computer. Common output devices include
- monitors
- printers, and
- speakers
The storage devices:
Storage is necessary for future reference. Process data that has been converted to useful information needs to be stored. Storage devices are used for such purposes. Storage devices are used to store data or instructions on a computer. Common storage devices include
- hard drives
- solid state drives.
- and optical drives.
- memory cards
- flash drives
The arithmetic and logic units
Arithmetic and logic units are used to perform arithmetic and logic operations on data. Arithmetic operations include addition, subtraction, multiplication, and division. Logic operations include
- AND,
- OR,
- NOT,
- and XOR.
The control units:
Control units are used to control the fetching, decoding, and execution of instructions. The control unit fetches instructions from memory, decodes them, and then executes them.
The control unit is also responsible for managing interruptions. Interrupts are signals that indicate that an event has occurred that needs attention. Common events that generate interruptions include input/output operations, timer events, and memory errors.
Computer hardware is an important part of any computer system. By understanding the different components of computer hardware, you can better understand how a computer works.
