Ram upgradation

When it comes to upgrading your Mac, RAM is the easy choice. It’s inexpensive, it’s relatively easy to install, and it can make a noticeable difference. But as a quick visit to just about any Mac forum will tell you, RAM upgrades can also be horrifically frustrating. Here’s how to do it right.

The first step in upgrading your RAM is to decide whether you need to do so at all. Upgrading RAM doesn’t necessarily help apps run faster. But it can speed up the processes of opening or switching between apps—something some of us do several times a minute. If those processes feel faster, so will your overall computing experience.

The reason for this is that OS X swaps apps and documents in and out of memory all the time. When the programs you’re running require more RAM than you’ve got, OS X moves programs that aren’t doing anything at the moment from active memory to temporary swap files on your hard drive, to make RAM available for the apps you’re really using.

Computers are very similar; they can continue processing without interruption as long as all needed information is in memory (RAM). When that is not the case, the computer stops, retrieves the needed information from storage (i.e. Hard drive, CD, disk) and places it into memory and then continues processing. The more interruptions the computer receives to retrieve information the slower the computer. The more memory a computer has, the fewer interruptions and the faster the computer operates. More memory equates to more speed.
