What are the different ram?

Answer 1

There are a number of different modules of memory also known as Ram.

These are SDram (this has 2 slots on the memory chip. One in the middle, the other at the end)

DDR Ram (This has 1 slot, directly in the middle)
DDRII Ram, This has 1 slot, in a slightly different place from the middle)
RAMBUS. (This has 2 slots, again in the middle)

Each type of ram, has different speeds of running.

Example, SDRam the speeds are 66, 100 & 133 Mhz
DDR, 2100, 2700, 3200 Mhz
DDRII, 4200, 5400, 6400, 7200Mhz
Rambus 400, 800Mhz

Hope this helps
