Arithmetic Logic Unit (ALU) - Responsible for performing arithmetic operations in the CPU. ASCH - 8-bit coding scheme, which means that 8 bits are used to represent uppercase and lowercase letters, mathematical operators, and logical operations. Benchmark - A test run by a laboratory or other organization to determine processor speed and other performance factors. Binary System - Number system consisting of two digits, 0 and 1. Bit (Binary Digit) - Smallest unit of data a computer can process. Bus Width - Determines the speed at which data in a computer travels, also referred to as word size. Byte - Field size for Number fields that allows entries only from 0 to 255. Cameras - Input devices that support adding pictures or videos to a computer. Central Processing Unit (CPU) - Complex integrated circuit; consists of millions of electronic parts and is primarily responsible for converting input (data) into meaningful output (information). Clock Speed - The speed at which a processor can execute instructions. Clock speed either can be measured in megahertz (MHz) or gigahertz (GHz). Cloud Storage - Storing electronic files on the Internet, not on a local computer; often called storing data
