RAM as One Factor for Data Processing Speed of Your Computer
RAM, the abbreviation for Random Access Memory, is usually referred as short-term “memory." Memory or RAM is computer hardware that has a vital function as temporary data storage. Memory works by storing and supplying the necessary data for processor to be processed into information. To be more easily understood about memory, as an example, when you open an application / file (or any extension word, html, jpg, etc.) that information (a command to open the file) does not necessarily go toward to the processor, but through the memory, and then submitted to processor. By the processor that information is processed and then given instructions to other components to locate the file and open it. The process of opening this file will pass through the RAM and back. For example, when you minimize an open program or programs that work in the background (like antivirus, etc.), then they actually use the services of memory, in order to function properly. That's simple understanding about function of memory or memory.
If you want your activities in the computer to run smoothly then you should provide sufficient hard drive (at least for the operating system, which is usually located in drive: C), sufficient RAM, and a processor which has good performance.
What often happens is lack of memory on your computer. For example, a PC with P4 Processor, mounted on a 256 MB RAM, and hard drive (drive C) 10 GB. The 256 MB memory will certainly slow down your computer's performance.
In general, memory can be rewritten over millions of times, the memory can be likened to a blackboard and chalk that can be written and erased again. Memory is volatile, data stored by the RAM will be lost if the computer is turned off. For example the use of memory, when you open a site, your computer's memory is being filled with data provided by the site. However, you need a hard drive for long-term data storage.
