Understanding RAM

In this article will discuss one of the computer hardware that is very important is the RAM (RAM sense). RAM stands for Random Access Memory is usually referred to as short-term memory is. Memory or RAM is a computer hardware that serves as a temporary data storage. Memory works by storing and supplying the necessary data required by the processor quickly to be processed into information.
To be more easily understood as an example, when you open the application for example such as opening a microsoft or mozilla firefox browser then the processor will open a program or application from the hard drive and then load it into memory, or RAM. that's approximately a simple understanding of the function of memory, or RAM.
You can see how much memory is needed when running an application or program. How to right click on the desktop bar panel computer screen you then select Task Manager, or via the button CRTL + ALT + DEL on the keyboard.

Right-click on the panel bar, then select Task Manager

 Note on tap Applications, then it will show an application or program that is currently active,

On tap performance PF usage note in the column, there are a number of figures (that is the amount of memory required to display the application). More and more applications are active, the more memory is needed. Keep in mind also, even if you do not open the app at all no means PF Usage column will be the number 0, because the windows operating system also requires memory to be active or live in the computer.

To understand further your work can be seen in the illustration below memory or ram

when you turn on the computer, the first component is a processor works. Processor serves as a data processor and request data from the data storage area (storage), the Hard Disk (HDD). This means that the data is sent from the Hard Disk after a request from the processor.

But in practice this is difficult because of differences in technology between Processor and Hard Disk. Processor itself is a pure digital components, and will process the data very fast (high bandwidth current P4 6.4 GB / s with 800MHz FSB). While most of the Hard Disk technology is certainly quite slow mechanical than digital (Bandwidth or Transfer Rate Serial ATA HDD around 150 MB / s). Theoretically, the data speeds ranging Processor 46x faster than HDD. That is, if the processor waiting for data from the HDD supply will occur "Bottle-Neck" very severe.

So to overcome this, the necessary devices Main Memory (Primary Memory) or the so-called RAM. RAM Processor serves to assist in the provision of data "super fast" is needed. RAM works just like Digital HDD, RAM because all components are already using digital technology. With RAM, the processor does not need to wait for the shipment data from the HDD. Currently has a bandwidth of DDR2 RAM 3.2 GB / s (PC400), so as not to disturb the supply current motherboard uses Dual Channel technology which can double the bandwidth becomes 2x zoom in to 128-bit architecture. That means, 2 pieces of DDR2 in Dual Channel mode can supply the data to the appropriate number of Processor (3.2 GB / sx Dual Channel = 6.4 GB / s).

That's a little explanation about the meaning and function of RAM or RAM memory, may be easily understood and can be useful for you who need it.
