- 5. MONITOR A monitor or a display is an electronic visual display for computers. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size.
- 6. MOUSE In computing, a mouse is a pointing device that detects two- dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows for fine control of a graphical user interface.
- 7. KEYBOARD A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However, to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters, numbers or signs (characters), other keys or simultaneous key presses can produce actions or execute computer commands.
- 8. PRINTER In computing, a printer is a peripheral which makes a persistent human readable representation of graphics or text on paper or similar physical media.
- 9. MODEM A modem (modulator-demodulator) is a device that modulates signals to encode digital information and demodulates signals to decode the transmitted information.
- 10. SPEAKER Computer speakers, or multimedia speakers, are speakers external to a computer, that disable the lower fidelity built-in speaker.
- 11. CHARACTERISTICS OF A COMPUTER 1. Speed 2. Accuracy 3. Reliability 4. Storage Capacity 5. Versatility 6. Reduction in Manpower 7. Reduction in Paper Work
