The part of a bus that carries data. When referring to the width of a bus, you are usually referring to the width of the data bus.
a bunch of wires that go to several devices in parallel
a path for transmitting data between devices
The path along which data is transmitted within the computer. The wider the data bus, the more data can be transmitted at once.
(n.) A group of signal lines (wires) that is used as a common pathway among multiple devices in a computer system.
A group of parallel conductors (circuit traces) found on the motherboard that is used by the CPU to send and receive data from all the devices in the computer. Also called the external data bus.
Lines or paths on the system bus that the CPU uses to send and receive data.
Bidirectional lines that carry data between the CPU and memory, or between the CPU and I/O devices.
A set of electrical signals connected to the processor and all of the memory and peripheral devices with which it communicates for the purpose of transferring data between them. When the processor wants to read (write) the contents of a memory location or register within a particular peripheral, it sets the address bus pins appropriately and receives (transmits) the contents on the data bus. One unit of data is transferred in each memory cycle.
System of lines over which data are transferred electronically in parallel or serially.
