The role of computer memory is to assist the processor by temporarily storing instructions and other information for faster processing. Computer programs, also known as applications — Microsoft Word, for example — require computers to have a specific amount of memory available for their use. Memory is measured in gigabytes (GB).

Your computer’s current memory capacity can be found on the same page as its processor speed. (See the preceding section and Figures 3-1 and 3-2.) Most newer computers come with plenty of memory, right off the shelf. However, if your computer is a few years older, it may not meet the minimum requirements for taking an online course. If this is the case, talk to either the institution’s technical support team or a computer retailer about increasing your computer’s memory. Depending on how old your computer is, increasing its memory may be all you need to do.
