Definition:

The "720" part of 720p describes the number of vertical lines that make up a television or video signal. Most television or video signals are rated at 480, 720 or 1080. The more vertical lines that make up the picture, the crisper or higher definition the picture. The "p" following 720 indicates that the video display is constructed using a progressive scan method.

720p is considered a middle-of-the-road high definition format and many television stations have begun digitally broadcasting in 720p as an initial high definition offering.

memory

Memory is what a computer uses to keep track of all the processes or applications that are running on the computer. It is much like the memory of a human in that the more memory you have the more you can remember. Computer memory is considered volatile since it is wiped clean when a computer is powered off.
