Memory Type: DDR PC2700, DDR PC3200, DDR (non-ECC)
Maximum Memory: 4GB
Slots: 4

Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.If your model uses the Pentium 4 with a 800MHz Front Side Bus (FSB) you must use the PC3200 parts. If your system has the Pentium 4 with the 533MHz Front Side Bus (FSB) you can use either the PC2700 or PC3200 parts.

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found here.

Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.

External Drive Bays -- 2 x 5.25" and 1 x 3.5"

Internal Drive Bays -- 2 x 3.5"

Storage Drives -- hard drives and solid state drives -- are the permanent memory for the programs and documents on your computer.

Data Transfer Rate is the rate at which data can be sent or received. This is determined by your motherboard. A drive with a higher transfer rate will only run at the rate of the motherboard's transfer rate.

Cache is a type of working memory that allows the drive to perform faster.

RPM is the rotations per minute of a hard drive which effects the speed of data transfer.

Solid State Drives are non-moving memory, so access speed is instant.

Chipset is a set of integrated circuits that have a specific purpose in a computer system, a group of microchips used together to perform a single task.

External Connector: 15-hole connector

Graphics Card A circuit board fitted to a computer containing the necessary video memory and other electronics to provide a bitmap display. Adaptors vary in the resolution (number of pixels) and number of colours they can display, and in the refresh rate they support. These parameters are also limited by the monitor to which the adaptor is connected.
