Well, that depends. You left out whether that is kilobytes, megabytes, or whatever. If you mean megabytes, then that is four gigabytes, or four "gigs" if you will. Note, however, that unless you are running a 64bit version of windows, you will only be able to use 3GB of that.
Typically, almost all laptops & PCs have atleast 1GB of RAM. With better & faster operating systems coming out, there are lots of computers with 2GB RAM and more.
The typical laptop has around 4 Gigabytes (4096 MB) of RAM memory.
Oh, dude, 4096 is just 2 to the power of 12. So, like, 2 multiplied by itself 12 times equals 4096. It's like exponential math, but, you know, not a big deal or anything.
No, it depends on the computer. DDR2 RAM is only for newer computers (Core 2, &tc.)
most computers have between 1 and 4 gigabytes of RAM
4096
It is much bigger than a normal computers RAM. Going into Terabytes.
Most computers will hold about 1-2GB of RAM but it depends on the computer.
There are many modules or computers on a 2012 Ram truck.

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.
