How memory address is generated
WebA physical address refers to an actual physical address in memory. A logical address is generated by the CPU and is translated into a physical address by the memory management unit(MMU).

WebSep 6, 2024 · 1. If each memory address can hold 1 byte (8 bits) of data. That’s not exactly right—it’s not that memory is partitioned into an array of boxes, each of which is 1 byte in size; it’s that 1 byte is the smallest addressable unit of memory. You can address memory in larger increments. So if you have a pointer char *p containing some ...
