RAM, which refers to Random Access Memory, is a computer storage media which could be accessed way quicker than a hard disk drive, due to the fact that the information can be read randomly, skipping the bytes before the needed data is reached. On a server, the RAM is employed to load scripts and web programs once they are executed, so the more RAM you are able to use, the more apps you shall be able to run at the same time and the more people will be able to check out your Internet sites with no effect on the site’s/server’s overall performance. Unlike a disk drive, however, the RAM is used for non permanent storage purposes, due to the fact that the info is lost the moment the power is shut off. When you use a shared web hosting account, the physical memory that your scripts can use may be limited and might change depending on what the some other clients on the same hosting server use. Through a virtual or a dedicated server, alternatively, you will have a guaranteed amount of RAM which will not be used by anyone else even if you do not use it at a certain time.
