- 2. Application software is a program or group of programs designed for end users. Examples of an application include a word processor, a spreadsheet, an accounting application, a web browser, an email client, a media player, a file viewer, simulators, a console game or a photo editor.
- 6. a small, portable personal computer with a "clamshell" form factor, typically having a thin LCD or LED computer screen mounted on the inside of the upper lid of the clamshell and an alphanumeric keyboard on the inside of the lower lid.
- 10. an electroacoustic transducer; a device which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker is the dynamic speaker. The sound source must be amplified or strengthened with an audio power amplifier before the signal is sent to the speaker.
- 11. A central processing unit, also called a central processor, main processor or just processor, is the electronic circuitry within a computer that executes instructions that make up a computer program.
- 12. A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets.
- 14. a computer or computer program which manages access to a centralized resource or service in a network.
- 16. a printer is a peripheral device which makes a persistent representation of graphics or text, usually on paper. While most output is human-readable, bar code printers are an example of an expanded use for printers.
- 17. a rigid nonremovable magnetic disk with a large data storage capacity.
- 19. System software is software designed to provide a platform for other software. Examples of system software include operating systems like macOS, GNU/Linux, Android and Microsoft Windows, computational science software, game engines, industrial automation, and software as a service applications
- 20. any piece of computer hardware equipment which converts information into human-readable form.
- 21. Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named after the NAND and NOR logic gates.
- 24. 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 of a computer.
- 25. a combined device for modulation and demodulation, for example, between the digital data of a computer and the analog signal of a telephone line
- 26. A computer keyboard is a typewriter-style device which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches.

- 1. :Computer hardware includes the physical parts of a computer, such as the case, central processing unit, monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard. By contrast, software is the set of instructions that can be stored and run by hardware.
- 3. Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.
- 4. a machine that processes something.
- 5. a piece of computer equipment on which information can be stored.
- 7. a piece of equipment used to provide data and control signals to an information processing system such as a computer or information appliance.
- 8. 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.
- 9. a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.
- 13. a portable computing device such as a smartphone or tablet computer.
- 15. a personal computer designed for regular use at a single location on or near a desk or table due to its size and power requirements.
- 18. Cloud storage is a model of computer data storage in which the digital data is stored in logical pools, said to be on "the cloud". The physical storage spans multiple servers, and the physical environment is typically owned and managed by a hosting company.
- 22. A computer case, also known as a computer chassis, tower, system unit, or cabinet, is the enclosure that contains most of the components of a personal computer.
- 23. A computer monitor is an output device that displays information in pictorial form. A monitor usually comprises the visual display, circuitry, casing, and power supply
