Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers.
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
USARTs in synchronous mode transmits data in frames. In synchronous operation, characters must be provided on time until a frame is complete; if the controlling processor does not do so, this is an "underrun error," and transmission of the frame is aborted. USARTs operating as synchronous devices used either character-oriented or bit-oriented mode.
The Synchronous Backplane Interconnect (SBI) was the internal processor-memory bus used by early VAX computers manufactured by the Digital Equipment Corporation of Maynard, Massachusetts. The bus was implemented using Schottky TTL logic levels and allowed multiprocessor operation.
Usually in SMP the coherency is based on the "Bus watching" or "Snoopy" (after the Peanuts' character Snoopy) approach. In a snooping system, all the caches monitor (or snoop) the bus transactions to intercept the data and determine if they have a copy on its cache. Various cache-coherency protocols are used to maintain data coherency between ...

The bus is an advanced, configuration-free synchronous bus used on DEC's later VAX computers. Like the Unibus and Q-Bus before it, it uses memory-mapped I/O but has 32-bit address and data paths. The VAXBI is a multiplexed bus with fully distributed arbitration and geographic addressing.
