• Chip set
A group of computer chips or integrated circuits (ICs) that, when working together, manage and control the computer system. This set includes the CPU and other chips that control the flow of data throughout the system.
• Address bus
A group of parallel conductors (circuit traces) found on the motherboard and used by the CPU to "address" memory locations. Determines which information is sent to, or received from, the data bus.
• Expansion slots
Specialized sockets that allow additional devices called expansion cards or, less commonly, circuit boards, to be attached to the motherboard. Used to expand or customize a computer, they are extensions of the computer's bus system.
Establishes the maximum speed at which the processor can execute commands. Not to be confused with the clock that keeps the date and time.
Protects unique information about the setup of the computer against loss when electrical power fails or is turned off. Also maintains the external date and time (not to be confused with the CPU's clock).
• Random Access Memory (RAM)
Stores temporary information (in the form of data bits) that the CPU and software need to keep running.
