Hi I am studying the computer science Hardware. I have one question. I studies processor strurcture and came to know that the processor sends the request of read and write commands to the memory unit if doesnt see the data or instruction in its registers. The processor use to send these commands in bulk as these requests are buffer some where in the memory controller hub. But when the memory return back the data it simply sends the data so how does the processor knows that this data or instruction belongs to specific process or what mechanisms it will  deploye to clasify the information comming back from the memory  or I/O. For example the processor sends the address and data to be fetched back from I/O and then again it sends the request to  fetch but this time from memory. When the data returns its simply the bits so how does the processor classify that the particular information belongs to which page or which processor ?
Memory Data Retrieve?
