It's a short term memory or area for quick calculations: like the top of your desk, getting papers off of it is very fast, but it is limited. Hard drives are like the drawers in the side of the desk - can hold a bunch of information but is very slow. If you are doing a project with papers, you put the most important on the top of the desk and get what you need from the drawer as you need. RAM = Random Access Memory. The random means you can access any place in the memory without having to read all the data before the chunk you want (sequential access: tape drives.)
No, it depends on the computer. DDR2 RAM is only for newer computers (Core 2, &tc.)

Ram in a computer can be found in multiple capacities. 64mb to up to 8gb for each slot (computers typically come with 2 to 4 slots for Ram). Certain computers have the downfall of having a limitation to how much Ram can be added.
In computers, RAM is used for temporary storage. PDAs, however, use RAM as their main storage. 99% of the apps you install are saved to RAM.
Yes! Apple Macbook Air Laptops usually have 4GB of ram. The RAM is NOT user accessible. 4Gb of RAM is a great amount of RAM for a standard user.
The first RAM was the Williams-Killburn tube CRT memory in the late 1940s.
micro DIMMs
ROM (Read-only memory) is storage used in the older computers. It can not be modified or changed in any way. It is mainly used to distribute firmware. RAM (Random-access memory) is a form of storage data, which most modern computers use. RAM can be bought in strips and slot into computers circuit boards.
