RAM is an acronym for Random Access Memory that is also known as volatile memory, because the data it holds is lost when the desktop PC or laptop/notebook computer using it is switched off.
The amount of RAM memory used in modern computers is expressed in megabytes (MB) and gigabytes (GB). A gigabyte (1GB) is 1024MB.
Most of the current desktop PCs and laptop PCs have motherboards that use DDR or DDR2 memory. However, DDR3 memory is now available, so, as time goes on, more motherboards will be using it.
When upgrading memory, it is essential that you purchase the right type of memory module, because DDR, DDR2, and DDR3 memory is incompatible with each other. You cannot use a DDR2 module in a DDR DIMM slot, etc.
Dynamic random access memory (DRAM)
