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 memoryforcomputer 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, memoryforcomputer 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.

FEATURES RAM comes in the form of a chip, and to increase memory, you simply plug additional chips in to slots on your computer''s main board. The capacity of a RAM chip is measured in megabytes, or millions of bytes. Most systems now come with 48MB of RAM and up. You should have at least 32MB of RAM for running Windows, but memoryforcomputer with the ever-growing memoryforcomputer demand for memory, 64 MB or higher is ideal. BUYING TIPS Before buying additional memory for your computer, consult the hardware manual that came with your computer. The manual will tell you what kind of memory is required for your system. It is also important to check the number of RAM slots memoryforcomputer in your computer, as there is a limited number on the main board for installing memory (anywhere from two to eight). You can only install as many memoryforcomputer memory modules as you have slots, so plan ahead. If you want to add or upgrade to 128MB of RAM, for instance, get a single 128MB RAM chip, not two 64MB modules. This will save you one RAM memoryforcomputer slot for future expansion.

You can think of RAM as an incredibly fast hard drive that stores information temporarily instead of permanently. When you start a program it is loaded from the hard drive into RAM. When a program is running in RAM it can run hundreds to thousands of times faster than it can if run directly from the hard drive. The problem is that the capacity of a standard hard drive is many times the size of a computer''s RAM size, meaning it is possible to load so many programs that the RAM can no longer hold them. When that happens, your computer''s memoryforcomputer virtual memory kicks in, and memoryforcomputer that''s bad. Virtual memory is simply your hard drive trying to act like a RAM chip. Since the hard drive is so much slower than real memory, programs stutter and sometimes crash when the hard drive has to do a job it was never designed for. There are only two solutions to this problem: close some programs until virtual memory memoryforcomputer is no longer needed, or add more physical memory. If you can afford it (and current memory prices are low enough that practically anyone should be able to), the latter solution is always preferable.
