DDR Computer Memory Upgrade Chips
To install memory, open the computer box and locate the memory sockets. You should unplug the computer's cables and peripherals, and re-install them afterward. Check your computer manual for specific installation instructions.
There are two basic types of computer memory: DRAM (Dynamic Random Acess Memory) which has to be continually refreshed or it loses its data; and SRAM (Static Random Access Memory) which is faster than DRAM, but costs more and uses more power.
RAM stands for Random Access Memory, commonly referred to as Temporary Memory. Nothing is actually stored here long-term- all storage is done via the hard drive. RAM does store data if your power goes off and is necessary for the computer to process data.
When you give your computer an "assignment" or task to work on, RAM temporarily stores the information until the job is done.
In most of today's computer systems, 64 MB is probably the minimum amount that your computer should have in order to run. 128 MB RAM would be preferable.
The BIOS of your computer might be described as your computer's central nervous system. This is what really makes your computer run. The BIOS sends commands to the computer's peripherals through the motherboard. It can also detect errors and send error messages to the user.
A computer's ability to store data is determined by the size of its hard drive. Example: a 4 Gig Hard Drive holds 4 gigabytes of data.
RAM is determined by megabytes. If your computer contains 12 Mg of RAM, that means that you can have 12 megabytes of data temporarily stored on your computer at any given time.
DRAM stands for Dynamic Random Access Memory and is the primary memory used by a computer's CPU. DRAM keeps copies of your programs, files, and other temporary data used by your CPU.
