Memory
DDR2 is a memory architecture that enables systems to improve performance and reduce power consumption. The amount of RAM you have is one factor that determines how many programs can be executed at one time and how much data can be readily available to a program. It also determines how quickly your applications perform and how many applications you can easily toggle between at one time. Simply put, the more RAM you have, the more programs you can run smoothly and simultaneously.
