Guide To Buying Computer Memory

Computer memory is commonly known as RAM, which is an abbreviation for random access memory. This memory card is located in a special place inside your CPU. This is the place where all the information about the applications and data that are currently being used is stored by the operating system. The main function of this kind of memory is to allow quick access to the computer’s processer so that all the applications can be processed quickly.

RAM is by far the fastest type of memory to read and write from especially when compared to the other kinds of storage devices that you will be able to find in a conventional computer. This includes the hard disk, the CD-ROM as well as the floppy disk.

What differentiates this kind of computer memory from the ones mentioned above is the fact that this kind memory can only be used as long as the computer is switched on. In other words it is not meant to serve as memory storage device for you to record your permanent data on. The moment you turn off your computer all the data that was on the RAM is lost. However the moment you turn it on again all necessary files will be loaded onto your RAM in order to be used. These files are transferred from the permanently stored data on your hard disk.

In order to understand it in a more comprehensive manner you can compare computer memory to the short-term memory found in human beings where the hard disk acts as the long-term memory. In this respect the process of RAM is to take care of the workload at hand whereas the hard drive stores the long-term data. Ideally you would want both of these to be working fast so that all the processes in your computer can be completed faster.

You will be able to find different kinds of memory cards for your computer. The first of these is the SDRAM. This is the cheapest memory that you will be able to find in the market however it is also the slowest. Another kind is the DDR which is a very fast and efficient yet cost-effective solution to enhancing your computer’s memory. However the fastest available memory to date is the DDR2.

Irrespective of the particular kind of memory you go for it is important that your motherboard must have the capacity to work in cooperation with the particular type of memory that you use. You will be able to find many different brands that produce motherboards which have special slots for SDRAM and DDR. However these can not be used at the same time which is why you have to make a choice between the two.

The different kinds of RAMs have different operating speeds. Hence it is also important that your motherboard should have the capability to support these speeds. Furthermore RAMs operate at different megahertz and this is also something that needs to be taken into consideration when looking to buy new memory.
