Computers tend to run better and more reliably when they have sufficient internal Random Access Memory, RAM. Memory prices have dropped dramatically, so it makes good sense to begin with 2 GB of RAM.

When either upgrading or buying a new system, pay special attention to:

• The number of free memory slots in the computer. Some inexpensive ones will have only two slots with one already filled, limiting your options to upgrade the memory.
• Whether memory must be installed in pairs or not. Consult your manufacturer.
• The correct memory type for your machine. Some computers may have special requirements.
