Hi
Please have a look on the following linked scanned page:

Please remember that I'm neither a comp. science student nor of science in general. So, please keep you reply as simple and to the point as possible.
Suppose I have the USB drive attached to the computer having some some e-document on it. Here Flash drive is an input device. Right. When I click on that document stored in the flash drive, how would the instruction flow in the context of the diagram shown in the link? I think at first this instruction would flow to the hard disk, then to the RAM, then to the Cache Memory, then to the Control Unit, and if there are some numbers involved, then the Control Unit would send those number operations to Arithmetic Logic unit. Here the inflow path of the instruction ends. And from here the outflow path starts, and ends at some output device such as monitor or printer. Correct?i
Why does "Main Memory (RAM)" have atop three different kinds of memories "ROM, PROM, Flash"? Does this mean that the RAM is divided into three different kinds of memory?
What does those "dots" there in the diagram mean?
Does the instruction from the Main Memory first goes to Control Unit instead of AU?
Please guide me. It would really kind of you. Thanks.
