Difference between memory bus and address bus

Question

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

Answer 1

When you read data from memory or write data to memory you operate with 2 different items, the address and the data. Somehow they have to be transferred between the CPU and memory. You can have two buses to transfer them independently. Or you can have just one and use it for both, one thing at a time.

Address and data buses may have different widths, that is, they may carry different number of bits.

Yes, memory bus usually means data bus (that carries the memory data).
