Web Cam A camera connected to a computer that allows anyone connected to the Internet to view still pictures or motion video of a user. Joystick A computer joystick allows an individual to easily navigate an object in a game such as navigating a plane in a flight simulator.
Keyboard One of the main input devices used on a computer, a computer keyboard looks very similar to the keyboards of electric typewriters, with some additional keys. Microphone Sometimes abbreviated as mic, a microphone is a hardware peripheral that allows computer users to input audio into their computers. Below are some examples of different types of output devices commonly found on a computer. Monitor A monitor is a video display screen. They are light, compact, take up They are heavy, bulky, take up a lot of desk very little desk space emit no known radiation.
Printer A printer is an output device responsible for taking computer data and generating a hard copy of that data. Speakers Projector. Related Papers. By Abrahm Otl. Fundamental of computer by NCTI institute. Computer -Overview. By Erum Fida.

The best use of tape storage is for data that you do not use very often. An optical disc drive ODD is a disk drive that uses laser light or electromagnetic waves for reading or writing data to or from optical discs normally CD-ROM.
It is a data storage device that includes flash memory with an integrated USB interface. USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc. Peripheral devices are devices connected to the computer externally. If a peripheral device is disconnected, the computer will still be able to work; only functions performed by this peripheral device will not be available.
Here are the most used types of peripheral devices:. The most common and very popular input device which helps in inputting data to the computer. It consists of keys that are capable of inputting alphabets, numbers and special characters. You can also navigate using the keyboard and perform shortcut functions.
Mouse is the most popular pointing device and cursor-control device having a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU when the mouse buttons are pressed. It forms images from tiny dots, called pixels that are arranged in a rectangular form.
The sharpness of the image depends upon the number of pixels. It is a device used to move cursor position on a monitor screen. A scanner allows you to scan printed material and convert it into a file format that may be used within the PC.
A plotter is used to create high-quality visuals on paper. Plotters were used in applications such as computer-aided design, though they have generally been replaced with wide-format conventional printers.
A plotter gives a hard copy of the output. It draws pictures on a paper using a pen. It can be used to create presentation-charts, graphics, tables and high quality technical drawings.
There are two types of plotter. Computer Abbreviations. MS Word Keyboard Shortcuts. Try Computer Quizzes. Sign Up for Free Already have an account?
Sign In. CPU has following three components. Primary memory holds only those data and instructions on which computer is currently working. It is generally made up of semiconductor device. These memories are not as fast as registers. The data and instruction required to be processed reside in main memory.
This type of memory is also known as external memory or non-volatile. It is slower than main memory. CPU directly does not access these memories instead they are accessed via input-output routines. Contents of secondary memories are first transferred to main memory, and then CPU can access it.
Cache memory is a very high speed semiconductor memory which can speed up CPU. It acts as a buffer between the CPU and main memory.
It is used to hold those parts of data and program which are most frequently used by CPU. The parts of data and programs are transferred from disk to cache memory by operating system, from where CPU can access them. Open navigation menu. Close suggestions Search Search. User Settings.
