• The computer system bus is the means by which data is exchanged between all of a computer's internal components. It connects the processor to the RAM, the hard drive, the video processor, the I/O drives, and all of the rest of the computer's components.
• In a computer, there are three sorts of buses that all flow together. The data bus lets data to flow between devices; the address bus instructs devices on where the data should go or come from; and the control bus controls activities among devices to avoid data conflicts.
• The term 'collisions' refers to data corruption caused by simultaneous use of the data and/or address buses.
• A computer bus is made up of a series of parallel conductors that can be wires, copper tracks on a PRINTED CIRCUIT BOARD, or minuscule aluminium trails on a silicon chip's surface.
