What is the confusion about RAM?
Most
of the computer users do some research before upgrading their system
so they exactly know about a perfectly matching CPU, motherboard and
video card combination that will meet all their needs. But most of
them fail when it comes to RAM. They just know the size of the RAM
i.e. 1GB, 2GB or 4GB, but they don’t know what this DDR1, DDR2 or
DDR3 is all about.
