Logical & physical address space
Did you know?
WitrynaI understand the concept of logical address, and physical address when it comes to computer memory. That is, physical is the actual address and logical address is what the applications think the address is. The operating system that lives between the applications and the physical memory translates between the programs memory and … Witryna29 kwi 2015 · The physical memory is 2^25 bytes and the frame size is 2^10 bytes. So the number of frames in the physical address space is (2^25)/ (2^10) = 2^15. Each process has its own logical address space. That may be smaller than the physical address space. But at a given time there are more than one process running.

Witrynaoperates in its own address space, under the assumption that it has the entire address space to itself. A virtual address requires translation into a physical address to actually access the system’s memory. Memory Management Unit - The memory management unit (MMU) is responsible for trans-lating a process’ virtual addresses into the ... WitrynaPhysical Addresses Space is a set of all Physical addresses generated in a program. Also, Logical Addresses Space is a set of all Logical addresses generated in a program. Physical addresses and Logical addresses need the same time for compiling and load time addresses binding schemes.
