Hello, im struggling trying to figure out this question for Computer Operating Systems. Much help would be greatly appreciated, thank you.

If a program contains 512 bytes and an operating system using a page frame size of 200 bytes. Use this to figure out:

A.) How many bytes of external fragmentation exists when the entire program is stored in memory?

b.)How many bytes of internal fragmentation exists in page frame containing the first page of the program?

C.)How many bytes of internal fragmentation exists in page frame containing the last page of the program?

D.)What affect if any, would doubling the available cache memory have on Average Memory Access Time?
