Computer Fundamentals

2. = The physical components that a computer system requires to function.
5. = A device used to store frequently accessed data and have it readily available to increase the performance of the computer.
8. A base-2 number system composed of both ones and zeros. Each binary digit (1 or 0) is one bit long. An example of a binary number is 1101, which is four bits in length.
10. = A computer program or device that provides a service to another computer program and its user.
11. An external device that is used to send data and to provide an input/output interface for a computer.

1. = The processor is essentially the heart of a computer and is responsible for processing information through input and output functions.
3. An electrical measurement of power.
4. =Also known as the mainboard, system board, main circuit board, or logic board.
6. An open-source OS that is completely free for any users who want to install it. This OS is mostly used on servers.
7. The measurement of the electric current’s force or pressure.
9. =A device that converts electric current and supplies power to an electrical load.
11. =The newer PCI interface is used for connecting high-speed expansion cards. PCIe comes in different physical sizes; x1, x4, x8, x16, x32, and describes how many bus lanes are connected to the card.
