Computers are important because they are accurate, fast, and can accomplish many tasks easily. They make life easier for humans in various ways by allowing people to reconnect with friends and watch shows they missed. The basic parts of a computer include the monitor, CPU, keyboard, mouse, microphone, speakers, printer, and webcam. The monitor displays video and graphics, the CPU carries out computer programs, the keyboard allows text entry, the mouse controls the pointer, the microphone captures audio, and the speakers output sound. The printer transfers information to paper and the webcam feeds video in real time to a network. Technology and computers have become integral parts of modern life.

- 1. The Basic Parts Of A Computer Presented By: Rhea Aguado
- 3. Why are computers so important? • Computer is an electronic device used in almost every field even where it is most unexpected. That is why this age is called as the era of IT. ... Computer has become very important nowadays because it is very much accurate, fast and can accomplish many tasks easily.
- 4. Why is computer helpful to us? • Computers make life easier for human beings in various ways. They allow people to reconnect with friends they haven't seen in decades and to watch television shows that they may have missed during the week. People are even able to complete a college degree or work from home solely depending on computers.
- 5. MONITOR
- 6. A computer monitor is an electronic device that shows pictures for computers.Monitors often look similar to televisions. The main difference between a monitorand a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions. The main function of a computer monitor is to display video and graphical information generated by the computers graphics adapter, allowing the user to interact with the computer. It is categorized as an output device.
- 7. CPU
- 8. A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions.
- 9. KEYBOARD
- 10. In computing, a computer keyboard is a typewriter-style device which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Following the decline of punch cards and paper tape, interaction via teleprinter-style keyboardsbecame the main input method for computers. A computer keyboard is an input device used to enter characters and functions into the computer system by pressing buttons, or keys. It is the primary device used to enter text. A keyboard typically contains keys for individual letters, numbers and special characters, as well as keys for specific functions.
- 11. MOUSE
- 12. A computer mouse is a hand-held 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 a smooth control of the graphical user interface. A mouse is a handheld pointing device used to position a cursor on a computer screen. This allows the user to select items stored on a computer and, subsequently, perform actions on those items.
- 13. MICROPHONE
- 14. Microphone. A microphone is a device that captures audio by converting sound waves into an electrical signal. This signal can be amplified as an analog signal or may be converted to a digital signal, which can be processed by a computer or other digital audio device. Loudspeaker, a transducer that turns an electrical signal into sound waves, is the functional opposite of a microphone. Since a conventional speaker is constructed much like a dynamic microphone (with a diaphragm, coil and magnet), speakers can actually work "in reverse" as microphones.
- 15. SPEAKERS
- 16. A device that converts analog audio signals into the equivalent air vibrations in order to make audible sound. When CRT monitors were the norm, speakers designed for computers were shielded to avoid magnetic interference with the CRT's magnetic coil. Getting Smaller All the Time. Speakers. ... Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.
- 17. PRINTER
- 18. A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing. In 1938, Chester Carlson invented a dry printing process called electrophotography commonly called a Xerox, the foundation technology for laser printers to come. For years, nobody seemed to pay any interest to Carson's invention.
- 19. WEB CAMERA
- 20. A webcam is a video camera that feeds or streams its image in real time to or through a computer to a computer network. ... Unlike an IP camera (which connects using Ethernet or Wi-Fi), a webcam is generally connected by a USB cable, or similar cable, or built into computerhardware, such as laptops. A webcam is a small camera attached to a computer. They serve a variety of purposes, from taking still images to sending a live video over conference calls. Many laptops have a webcam built in to the computer screen, but externalwebcams are also sold.
- 21. Technology has forever changed the world we live in. We're online, in one way or another, all day long. Our phones and computers have become reflections of our personalities, our interests, and our identities. They hold much that is important to us. ~~~~ James Comey
