Most data is stored on the computers hard disk drive, but it can be quite slow to retrieve data from the hard drive. RAM, however is very quick when it comes to retrieving data, so the computer transfers programs and files into the RAM when they are in use.

When purchasing a computer how do i know how much ram i will need?

3-4Gb of RAM is about all you need. more RAM will just go unused unless you are doing a lot of 3D modeling (which im guessing your not). Less than 3Gb is not recommended as it may slow down your computer and RAM is cheap enough. If you are buying a computer with a Core i7 processor, then make sure the amount of RAm is a multiple of 3 (3 or 6Gb)
