Definition: A set of parallel conductors, which allow devices attached to it to communicate with the CPU.
The bus consists of three main parts:
These allow the CPU to control which operations the devices attached should perform, I.E. read or write.
Allows the CPU to reference certain (Memory) locations within the device.
The meaningful data which is to be sent or retrieved from a device is
placed on to these lines.
The Bus is set to run at a specified speed which is measured in MHz
|Q: Why do you think the Bus speed is pre-set?|
