You could see RAM as "drawers" on your desk..
If you're working on lots or big of projects (processes in the pc) you need lots of drawers to organize your work (e.g. files).. if your drawers are full you have to make "place" (e.g. copy files from RAM to your harddisk and back) which slows down/delays your work.
--> The more drawers (RAM) the more projects you can handle simultaniously without delays.
Add more RAM?...?
No, it is not possible to add unlimited RAM to any computer. Each computer has a maximum amount of RAM it can support, determined by its hardware limitations.
none
No, pc133 is SD ram and Pc3200 is DDR ram. They are not compatible with each other.
You may be able to add more RAM if you have 1 or more empty expansion slots.
Yes, In normal PCs, There are two modules for adding RAM, one is generally pre-occupied and one is left free to manually add RAM, If you add 1GB RAM with 256MB RAM, it will sum up to 1.25GB of RAM.
If your computer has 256mb ram only, you can add another 256mb ram in it..just go to your nearest computer store and buy another 256mb ram stick. once you have that, open you PC housing and put it in Dimm1 or Dimm 2.
Expanding the RAM means adding further RAM to your existing RAM. You could completely install new set of RAM or you can add a similar RAM to the existing one if one slot is empty.
If your laptop has available RAM slots then you can add it. Also you have to check how much of RAM your laptop can support. It's not more then 2 Gb. You can replace the RAM which you have now by RAM with more capacity. PS Some laptops do not allow to change or upgrade RAM (mostly old models and ASUS Eeee).
You add more RAM to it
No lol
Add more, you cannot not speed it up, but you can improve it by adding RAM memory.
