Ram on a computer stands for random access memory. This is a type of memory that is used by the computer to store data that is being actively used. When the computer is turned on, the operating system and the programs that are running are loaded into the ram. This is why it is important to have enough ram if you plan on running multiple programs at the same time. When the ram is full, the computer will start to use the hard drive to store data, which can slow it down.
