bus
Quick Summary
In computer science, a bus is a communication system that transfers data between components inside a computer or between computers. It is a collection of electrical pathways that connect various hardware components, allowing them to exchange information.
One crucial type of bus is the address bus. This element within a computer's central processing unit (CPU) transmits the location of stored information. When the CPU needs to access data from memory, the address bus specifies precisely where that data is located. This is distinct from the data bus, which handles the actual transfer of data once the location is known.1
Buses can be classified as serial or parallel. Parallel buses use multiple wires to transfer data simultaneously, increasing throughput, while serial buses transfer data one bit at a time. The Universal Serial Bus (USB) is a common example of a serial bus that can also transmit power.2

peripheral device…the most common interface, or bus, for magnetic disk drives. A bus (also known as a port) can be either serial or parallel, depending on whether the data path carries one bit at a time (serial) or many at once (parallel). Serial connections, which use relatively few wires, are generally…

computerPeripheral interfaces…nature is often termed a bus. This nomenclature derives from the presence of many paths of electrical communication (e.g., wires) bundled or joined together in a single device. Multiple peripherals can be attached to a single bus—the peripherals need not be homogeneous. An example is the small computer systems interface…
