WitrynaLogical Address is used as a reference to access the physical memory location by CPU. The Memory-Management Unit uses the address-binding methods for mapping the logical address to its corresponding physical address. virtual memory Virtual memory is memory outside the main memory and inside the hard disk WitrynaLogical Address space is define the number of distinguished memory location a system can read. On a Byte Addressable machine, a 32-bit system means that it can read up-to. 32 bits at a time. It means,it can read upto 2^32 different addresses. And hence, a 32-bit system can have 2^32 i.e. 4Gb of virtual address space.
