Q: I know a lot of ram is good but I don't understand what it's used for. Can someone explain it.
A: RAM = Random Access Memory It is used to hold a limited amount of data at one time, and be able to read and write that data faster than you can to a standard IDE/SCSI drive as they are slower access speeds. For example, say you are playing a game....every time you change screens or an animation happens, or tracking your score...the game would be quite a bit slower if it had to read from the hard drive for those files. However, putting those files in to RAM allows for faster access so you get continuous game play, as opposed to "lag".
