Detailed explanation-1: -Physical 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).
Detailed explanation-2: -Alternatively called physical storage or real storage, physical memory is memory that exists in the form of modules, like RAM. Essentially, it’s memory you can touch, unlike virtual memory, a method of creating memory by swapping data between RAM and a hard drive.
Detailed explanation-3: -Alternatively called main memory, primary memory, or system memory, RAM (random-access memory) is a hardware device that allows information to be stored and retrieved on a computer. RAM is usually associated with DRAM, a type of memory module.
Detailed explanation-4: -Until the 1970s, core memory remained in its place. After that, semiconductor memory has become economically competitive due to advancements in integrated circuit (IC) technology. This led to modern random-access memory (RAM) of a computer is known as a physical memory or primary memory.
