- 11. Computer System A computersystem is a complete set of hardware, software, peopleware, and data that work together to process information and perform tasks. .
- 13. Elements of aComputer System 1. Hardware- refers to the physical, tangible computer equipment and devices which provides support for major functions such as input, process, output and storage.
- 16. A.1. Keyboard A computerkeyboard 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.
- 17. A.2. Mouse The mouseis another input device used to point and select objects on the computer monitor.
- 18. A.3. Scanner A scanneris use to capture a source document and converts printed data or images into an electronic data format that a computer can store or process as required.
- 19. A.3. Microphone A microphoneis an input device to input sound that is then stored in a digital form
- 21. B.1. Monitor A monitoris an electronic visual computer display that includes a screen, circuitry, and the case in which that circuitry is enclosed.
- 22. B.2. Printer The printeris a device use to print texts and pictures.
- 23. B.3. Speaker A computerspeaker is an output hardware device that produces sound.
- 24. B.4. Projector A projectoris an output device that projects an image onto a large surface, such as a white screen or wall.
- 25. C. PROCESSING DEVICE isthe computer’s circuitry in the system unit. It plays an important role in processing operations. It is used to process data, using instructions from the program.
- 26. C.1. Motherboard / Mainboard/ System Board – is the main circuit board of a computer. It contains all the circuits and components that run the computer.
- 27. C.2. CPU (Central ProcessingUnit) - The processor is the main “brain” or “heart” of a computer system.
- 28. C.3. RAM –(Random Access Memory) RAM is volatile, meaning it holds data only when the power is on. When the power is off, RAM’s contents are lost.
- 29. C.4. Video Card/GPU(Graphics Processing Unit) - also called a display card, graphics card, display adapter, or graphics adapter is an expansion card which generates a feed of output images to a display device (such as a computer monitor).
- 30. Storage devices– are hardwaredevices used for storing information from the computer.
- 31. Flash drive is asmall rectangular device that is designed to be plugged directly into a USB port on a computer and is often used for transferring files from one computer to another.
- 32. Hard drive is aninternal hard drive is the main storage device in a computer. An external hard drive is also known as removable hard drive. It is used to store portable data and backups.
- 33. Optical disc is astorage device that uses laser technology to read and write data.
- 34. Computer SOFTWARE Computer softwareis a collection of instructions that tells the computer hardware how to work.
