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.

RAM (random access memory) is put on your computer using RAM chips placed into special slots. When your computer is turned off, RAM is empty-unlike a hard disk, it can''t store data unless the RAM is powered by electricity. Step 2: RAM''s Power Source When you turn your computer on, electricity flows from the power supply to the motherboard. Because the RAM is directly attached to the motherboard, it gets electricity from the motherboard. When RAM is powered by electricity, it can store data. Step 3: RAM and Hard Disk Relationship The data is now in memory and can be used, manipulated, and altered. The altered data stays in RAM only until you issue a command to save it. When you issue a Save command, the altered data is sent back over the bus to your hard disk, and the data is stored there. When you turn your computer off, the data vanishes out of RAM, but stays permanently on your hard disk.
