The document defines and describes common computer hardware components. It explains that a power supply provides electrical power to a computer, a microphone connects via USB to allow voice input, a keyboard uses buttons to input symbols, and a monitor displays video output without saving files. It also describes that a mouse is a pointing device that detects motion, speakers connect via audio jack to output sound, a webcam captures video using USB or Wi-Fi, and a flash drive stores data using USB connectivity.

3. Power Supply Power supply is a reference to a source of electrical power . A device or system that supplies electrical or other types of energy to an output load or group of loads is called a power supply unit or PSU . The term is most commonly applied to electrical energy supplies, less often to mechanical ones, and rarely to others.

4. Computer Microphone Computer microphone is a speaking device easily accessible through the computer. Commonly through USB, it is plugged into the main console of the computer.

5. Keyboard In computing , a keyboard is an input device , partially modeled after the typewriter keyboard , which uses an arrangement of buttons or keys , which act as electronic switches. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol .

6. Monitor A visual display unit , often called simply a monitor or display , is a piece of electrical equipment which displays images generated from the video output of devices such as computers , without producing a permanent record.

7. Mouse In computing , a mouse (plural mouses , mice , or mouse devices ) is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons.

8. Speakers Computer speakers , or multimedia speakers , are external speakers, commonly equipped with a low-power internal amplifier. The standard audio connection is a 3.5mm (1/8 inch) stereo jack plug often colour-coded lime green (following the PC 99 standard) for computer sound cards .

9. Webcam Webcams are video capturing devices connected to computers or computer networks , often using USB or, if they connect to networks, ethernet or Wi-Fi . They are well-known for their low manufacturing costs and flexible applications.

10. Flash Drive A USB flash drive consists of a NAND -type flash memory data storage device integrated with a USB (universal serial bus) interface. USB flash drives are typically removable and rewritable, much smaller than a floppy disk (1 to 4 inches or 2.5 to 10 cm), and most USB flash drives weigh less than an ounce.
