as noted in the introduction, there''s a virtual alphabet soup of memory types: sdram, edo, fpm, simm, and dimm. it certainly can create a great deal of confusion. ram itself stands for "random access memory," meaning the cpu can access any memory address without reading all addresses before it. (rom—read only memory—is random access, too, but you can''t write to it). it gets worse, because memory comes in different speeds, and some types don''t work in some systems. here''s the rundown on the three memory types used in today''s systems.... sdram. synchronous dram sdram''s speed is typically measured in mhz (for example, 100mhz), although you do see references to 10ns sdram ("ns" stands 2655xdvd for nanosecond or one billionth of a second). sdram for pcs comes in dimms. these refer to sdram dimms rated at different satellite memory bus speeds. for any cpu running at a 100mhz bus speed you should get sdram. some future motherboards will support sdram. although there''s a price premium, sdram will run in a pc100 system.

for example, you can add pc800 modules to a system that was designed for modules, but the memory will run at the speed. how much memory do i need? ask us and we will tell you every ounce and then a megabyte to spare. the answer really depends on how much and for what your system is used. upgrading is easy and cost effective. ram is used every time you open an application, download, play a game or simply turn on your computer. additionally if you work with or plan to work with digital audio and video more ram is a necessity. the amount of memory you need depends upon how you use your computer. most applications recommend a minimum of 64mb, and most users desire more than the minimum requirement. novice user / administrative if you use your computer to send and receive email, do a little word processing, and are starting to surf the web, you can get by with 64mb. however, you would benefit from going to at least 128mb of memory. basic user / student if you are spending more time surfing the internet, sending and receiving email, and doing word processing along with other applications, you can get by with 128mb, but would benefit from going to 256mb.
