  1. 3. A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet.
  2. 4. a kind of memory that retains data in the absence of a power supply.
  3. 5. Random-access memory is a form of electronic computer memory that can be read and changed in any order, typically used to store working data and machine code.
  4. 8. The Central Processing Unit (CPU) is the primary component of a computer that acts as its “control center.” The CPU, also referred to as the “central” or “main” processor, is a complex set of electronic circuitry that runs the machine's operating system and apps.
  5. 9. A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface.
  6. 11. A motherboard is a computer's main circuit board that connects all of its internal components. It allows these components to communicate and function together.
  7. 14. A computer speaker is a piece of hardware attached to a computer system used to produce sound. The computer's sound card has the signal used to generate the sound from a computer speaker.
  8. 16. A power supply unit converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer.
  9. 17. A monitor is an electronic output device used to display information being entered and processed on a computer. The primary use of a monitor is to display images, text, video, and graphics information generated by the computer via a computer's video card.
  10. 18. Cache memory is a type of data storage used to store frequently accessed information for faster response time.

  1. 1. A computer peripheral, also known as a peripheral device, is an external device that connects to a computer to expand its capabilities. Peripheral devices are not essential to the functioning of a computer, but they enhance its functionality.
  2. 2. a panel of keys that operate a computer or typewriter.
  3. 6. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks.
  4. 7. A solid-state drive is a type of solid-state storage device that uses integrated circuits to store data persistently.
  5. 10. a device for examining, reading, or monitoring something.
  6. 12. A graphics processing unit is a specialized electronic circuit initially designed for digital image processing and to accelerate computer graphics, being present either as a discrete video card or embedded on motherboards, mobile phones, personal
  7. 13. A hard drive in a computer is an internal or external device that stores data such as operating systems, applications and user files.
  8. 15. A printer is a device that prints documents and images onto paper or other materials. It is usually connected to a computer, allowing you to use your word processor, spreadsheets, and other programs to create documents and images that are printed out on the printer.
  9. 19. (Read-Only Memory) Read-only memory is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device.
