A bus is a shared pathway that enables the transfer of data between various hardware components, such as the central processing unit (CPU), memory, input/output (I/O) devices, and other peripherals.
-
Address Bus
- determines the location in memory that the processor will read data from or write data to.
-
Data Bus
- contains the contents that have been read from the memory location or are to be written into the memory location.
-
Control Bus
- manages the information flow between components indicating whether the operation is a read or a write and ensuring that the operation happens at the right time.
