i have a droid x. I have installed a program called "Advanced Task Killer". it is a free program that kills currently running apps. when I open "Advanced Task Killer, there is a section on the very top of the screen that says

"Available Memory: 219M"

The numeric value changes when I close applications that are running. Is this value the available "Ram" on the device? or what?

How much Ram or cache does this device come with? Is this a high or low number.

How can I improve this number to speed up my device? will clearing cache do anything to help? how do I do that? please advise
