Computer Components

2. a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted
6. a device that allows you to digitize physical documents, images, or even objects, and convert them into a digital format that can be viewed, edited, and stored on a computer
8. a group of systematically arranged keys by which a machine or device is operated
9. a type of computer memory that can only be read from, not written to

12. a hardware device that converts AC electricity into DC electricity and then distributes it to the rest of the computer
13. hardware attached to a computer system that provides the system with extra functions but does not contribute to its primary function
14. a specialized processor originally designed to accelerate graphics rendering
15. an output hardware device that connects to a computer to generate sound
16. a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level
17. an electronic output device used to display information being entered and processed on a computer
18. a type of computer memory that serves as a buffer between the Central Processing Unit (CPU) and the main memory (RAM)

1. allows devices to communicate with each other without cables or wires
3. a device for storing computer data that consists of one or more hard disks in a sealed case
