Can someone very briefly point out the differences between the memory bus and address bus in computer architectures ? Also when you say memory bus does it imply that you are ref

    Beautifully explained here.

    In isolation, the microprocessor, the memory and the input/output ports are interesting components, but they cannot do anything useful. In combination, they can form a complete system if they can communicate with each other. This communication is accomplished over bundles of signal wires (known as buses) that connect the parts of the system together.

    There are normally three types of bus in any processor system:

    • An address bus: this determines the location in memory that the processor will read data from or write data to.
    • A data bus: this contains the contents that have been read from the memory location or are to be written into the memory location.
    • A control bus: this 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.
