Computer components

3. a device that forwards data packets to the appropriate parts of a computer network.
4. A CPU, or Central Processing Unit, is the main part of a computer that processes data and instructions. It's also known as the processor or microprocessor.
5. a panel of keys that operate a computer or typewriter.
9. Graphics processing unit, a specialized processor originally designed to accelerate graphics rendering
10. Put simply, ROM is a non-volatile form of memory that stores data permanently and cannot be written over or erased.
11. RAM stands for random access memory, and it's a computer's short-term memory. It's where the computer stores data that it needs to run programs and open files
14. A solid-state drive (SSD) is a semiconductor-based storage device, which typically uses NAND flash memory to save persistent data.
15. A peripheral device is hardware attached to a computer system that provides the system with extra functions but does not contribute to its primary function
17. an instrument or device used for observing, checking, or keeping a continuous record of a process or quantity
18. a high-capacity, self-contained storage device containing a read-write mechanism plus one or more hard disks, inside a sealed unit. Also called hard disk drive.
19. a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.

1. A power supply unit (PSU) is a hardware device that converts AC electricity into DC electricity and then distributes it to the rest of the computer
2. a person whose job or business is commercial printing.
6. a small handheld device that is dragged across a flat surface to move the cursor on a computer screen, typically having buttons that are pressed to control functions.
7. a standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices.
8. Flash memory is a long-life and non-volatile storage chip that is widely used in embedded systems
12. a combined device for modulation and demodulation, for example, between the digital data of a computer and the analog signal of a phone line.
13. a person who speaks.
14. a device for examining, reading, or monitoring something.
16. cache memory, supplementary memory system that temporarily stores frequently used instructions and data for quicker processing by the central processing unit (CPU) of a computer
