Physical memory is the random access storage provided by the RAM modules plugged into your motherboard. Swap is some portion of space on your hard drive that is used as if it is an extension of your physical memory.
What is the main memory used for?
The main memory acts as the central storage unit in a computer system. It is a relatively large and fast memory which is used to store programs and data during the run time operations. The primary technology used for the main memory is based on semiconductor integrated circuits.

Ke hoʻohana nei ʻo Linux i ka hoʻomanaʻo virtual?
Linux supports virtual memory, that is, using a disk as an extension of RAM so that the effective size of usable memory grows correspondingly. … The part of the hard disk that is used as virtual memory is called the swap space. Linux can use either a normal file in the filesystem or a separate partition for swap space.
What is physical and virtual memory in Linux?
Physical and virtual memory are forms of memory (internal storage of data). Physical memory exists on chips (RAM memory) and on storage devices such as hard disks. … Virtual memory is a process whereby data (e.g., programming code,) can be rapidly exchanged between physical memory storage locations and RAM memory.
What is a physical memory?
Physical memory refers to the actual RAM of the system, which usually takes the form of cards (DIMMs) attached onto the motherboard. Also called primary memory, it is the only storage type directly accessibly to the CPU and holds the instructions of programs to execute.
