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 aptivamemoryupgrade 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.

Different Speeds of Memory The faster the memory, the faster a computer operates. Memory aptivamemoryupgrade comes rated at different speeds, and the faster the memory, the more it costs. Memory speed is measured in nanoseconds, and the lower the nanosecond rating, the faster the memory. For example, a 60 nanosecond chip is faster than an 80 nanosecond chip. Be sure that the memory you buy is as fast as the memory you''re replacing. Many newer, faster Pentiums come with RAM that can run at 100Mhz-the speed of the system bus. It’s always a good time to add random- access memory (RAM) to your computer. That’s because RAM is easy to install and can improve the performance of even the weakest computer. A couple of years ago, the average computer contained four megabytes (MB) of RAM. Now the standard is up to 16MB, with many new computers sporting 24MB or more. And users who play computer games or work with desktop publishing programs might have as much as 128MB of RAM.
