What difference between cache and ram?

Answer 1

"RAM" is Random Access Memeory. It's the high speed memory that's on the motherboard and allows the computer to load instructions and data quickly into the processor during normal operation.
"Swap" space is an area on the computer disk that has been reserved as space for overflow. When there are too many applications CURRENTLY RUNNING or applications that are CURRENTLY RUNNING that are too large, large blocks of data are swapped into the swap space, freeing up some of the high speed memory.
Typically, if the operating system is reasonably intelligent, data is only swapped to disk that is not currently being used.
Excessive disk swapping will slow your computer dramatically. It's always a good idea to remove unnecessary applications from your startup.
Your computer can have many applications on disk, as well as a lot of data. Only the CURRENTLY RUNNING applications can be impacted by swap space.

Answer 2

ram is the primary memory of computer while cache is the small memory space between CPU and ram where processor keeps frequently used instruction so that we can utilize from cache memory itself instead of disturbing processor every time..

it enhance the speed of system..

Answer 3

Its the same thing only virtual memory is used in Windows and swap space is a term used in Linux O.S
