Logical & physical memory
WitrynaPhysical memory (also known as random-access memory (RAM)) is a form of very fast, but volatile data storage. RAM modules are typically measured in nanoseconds (1000− 3 ), and physical disks are typically measured in milliseconds (1000 − 1 ). This makes physical memory roughly 100,000 times faster than a common physical disk. Witryna9 sty 2024 · logical versus physical address an address generated by CPU is commonly referred to a logical address. the address seen by memory unit is known as physical address logical address can be mapped to physical address by hardware with the help of base register this is known as dynamic relocation of memory reference. …
