Random Access Memory (RAM)
Random Access Memory (RAM) chips are to your computer what a blank canvas is to an artist. Before a PC can do anything useful, it must move program from disk to RAM. The data contained in documents, spreadsheets, graphics, database, or any type of fule must also be stored in RAM, if only momentarily, before the software can use the processor to manipulate that data.
Adding computer RAM is extremely easy. First, you need to unplug your computer from the wall and open your computer case to get access to the motherboard. Remove your RAM from its anti-static bag and hold it by the edges. The next step to install your RAM is to determine which slot to place it into. If you want to add IMAC Memory, I think you can follow the same steps that I have mentioned here.
Installing new RAM is a very cost effective way to give your computer some extra juice. May be you can try original DDR PC2700 Memory which it utilizes technology enabling up to 2-1/2 times the memory performance of traditional SDRAM.
Adding more memory is one of the least expensive ways to help boost overall system performance and allows more multitasking which saves time and hassle. If you think your PC has to upgrade RAM, you can just go ahead with low cost.
