1.1. INTRODUCTION
These days, no matter how much memory your computer has, it never seems to be quite enough. Not long ago, it was unheard of for a PC (Personal Computer), to have more than 1 or 2 MB (Megabytes) of memory. Today, most systems require 64MB to run basic applications. And up to 256MB or more is needed for optimal performance when using graphical and multimedia programs.
As an indication of how much things have changed over the past two decades, consider this: in 1981, referring to computer memory, Bill Gates said, “640K (roughly 1/2 of a megabyte) ought to be enough for anybody.”
For some, the memory equation is simple: more is good; less is bad. However, for those who want to know more, this reference guide contains answers to the most common questions, plus much, much more.
