Fast forward for computer memory
The memory in our computers is getting faster - it has to, as our processors get more powerful and software more complicated, so memory has to speed up to feed our data-hungry computers.
RAM (Random Access Memory) is the place where your computer stores all the data it needs right now to help you do what you want - be it play a game or write a letter.
It is different to data stored on your hard disk because it goes away when you switch the power off, disks are called storage because the data stays on them when you power them down.
Now, to make your computer to run faster, a new system called dual channel memory has been developed that, as its name implies, splits the RAM memory into two channels.
