Computer uses random-access memory or (RAM)
to store the operating system, any open applications,
and all data you're currently working on. Your computer
can access the data in RAM much faster than the data on
your computer's hard disk. If you have too little RAM,
it can slow down your computer or prevent you from running
applications and or completing tasks.
The DIMMs, or dual in-line memory modules,
are sold in multiples of 64 MB or 128 MB. All new computers
use (PC-100 SDRAM) or (PC-133 SDRAM) DIMMs. Consider buying
a computer with open DIMM sockets, so that you can add
more RAM easily. If you have no open DIMM sockets, you'll
have to replace some of your existing RAM to upgrade.
RAM is called "random-access" because the computer can
get information from any part of RAM directly - the computer
doesn't have to cycle through from the beginning of RAM
to find the data it's looking for. Choosing the Right Amount of Pc Memory RAM for Your New Computer! Remember to come back

Tip: Choosing the Right Amount of Pc Memory RAM for Your New Computer!
A. Consider buying a machine with lots of
RAM now, rather than adding it later, to take advantage
of the current low price of memory.
B. Choose a computer with at least 128 MB
of RAM to run Windows 98 or Mac OS 8.x and basic applications.
C. Choose a computer with 128 MB to 256MB
of RAM for working with scanned color photographs.
D. Choose at least 256 MB of RAM if using
professional graphics or design software or multimedia
software, with streaming video and audio.
If your computer doesn't have enough RAM,
it has to keep going back to your hard disk to get information
before you can work, which makes it slow.
Specifications: Choosing the Right Amount of Pc Memory RAM for Your New Computer!
A dual inline memory module (DIMM) consists of a number
of memory components (usually black) that are attached
to a printed circuit board (usually green). The gold or
tin pins on the bottom of the DIMM provide a connection
between the module and a socket on a larger printed circuit
board. The pins on the front and back of a DIMM are not
connected, providing two lines of communication paths
between the module and the system.
168-pin DIMMs are commonly found in Pentium and Athlon
systems. Each 168-pin DIMM provides a 64-bit data path,
so they are installed singly in 64-bit systems. 168-pin
DIMMs are available in FPM, EDO, 66MHz SDRAM, PC100 SDRAM,
and PC133 SDRAM. When upgrading, be sure to match the
memory technology that is already in your system. (Information
on which memory technology is used by your system is included
in the Memory Selector.)
The number of black components on a 168-pin DIMM may
vary, but they always have 84 pins on the front and 84
pins on the back for a total of 168. 168-pin DIMMs are
approximately 5.375" long and 1.375" high, though
the heights may vary. They have two small notches within
the row of pins along the bottom of the module. Choosing the Right Amount of Pc Memory RAM for Your New Computer!
