comment What are functional unit and control logic of a cpu?
Thanks. do you mean that you think that functional unit and execute unit the same thing in the book? (note that I am not sure about if execute unit and execution unit are the same). what about control logic?

comment What manages IO between a buffer and a device?
Thanks. What does ""only give data to the requesting program if the I/O completes successfully" mean? What is the opposite of "only give data to the requesting program if the I/O completes successfully"?

comment What determines the page size and the cluster size?
@sawdust Thanks. (1) Wikipedia says "Page size is usually determined by processor architecture. " So is a memory's page size determined by the CPU? A memory may have different page sizes when it is used by different CPUs? (2) You said that MMU put constraints on page size, and if I am correct, MMU is part of a CPU, so is your reply consistent with Wikipedia? (3) Is the OS not involved in determining the page size?

comment Maximum addressible/accessible filesystem?
(1) I didn't mix "memory" and "storage". I put "secondary" in front of "storage". (2) "As for why we measure in blocks, its because there isn't a constant amount of disk surface area per byte. it changes all over the disk. " Is the disk surface area for a block constant?

Thanks. How can chaining multiple sectors into a file system's block "reduce space"?

Sometimes questions should be concise to be clear.

comment Are the size of a memory page and the size of a file system cluster always the same?
@sawdust: is it always or almost always true that "The virtual memory manager will bypass the filesystem, and access the disk driver directly"?
