Also called RAM (random-access memory), memory is an important part of the functioning of any computer. Memory serves as a slate on which the temporary information that the computer needs to run an application is stored. The amount of memory in your computer is important because even if you have a fast processor, your computer will perform sluggishly if it doesn't have enough memory. Without enough memory to solve a task, your processor has to write and erase data several times, which takes much longer than if there is enough memory to store the necessary data. The more memory a potential notebook has, the better. Generally, 2GB or more of RAM will be plenty.
