Статья на тему "What is RAM?"

Hello dear friends. The world of high technologies is rapidly developing. Computer technologies are rapidly developing, and with them, applications and programs for these computers. Applications and programs began to consume system resources and RAM several times more than in previous years, when 64 or 128 MB was enough (for today, in my opinion, the minimum required amount of memory for a computer is 1 GB of memory). For example, the browser Mozilla Firefox since version 4 began to consume several times more RAM than before. In addition, almost all sites began to use in huge quantities all kinds of flash banners, which also consume not a small amount of RAM on your computer. In this article I want to tell you briefly about what exactly RAM is - RAM in general and its operating principle.

What is RAM?

RAM - random access memory or RAM or operative. In English, RAM is Random Access Memory, which means a random access memory. RAM is inherently a memory for temporary storage of information about running programs, services and processes. With the help of RAM, communication is made between the processor and hard disks (HDD), as well as any external devices. Any program is known to be executed directly in the processor of the system, and program files are located in the memory of hard disks. Before this program is executed, it is necessary that its executable files get into the processor. This is exactly what RAM is doing. It stores the files of all programs and applications currently running. When you exit the program, all of its files from the RAM are also deleted. The amount of RAM depends on how many application files it can store in its memory. The data transfer rate of hard disks is negligible compared to the processing speed of the processor, therefore for data reading it is necessary to use the services of a kind of intermediary between the processor and the disk drive, whose role is performed by the operative memory. When there is a shortage of RAM, the speed of the computer is noticeably reduced and just in such cases the so-called special paging file is used, otherwise the cache memory. It stores the most frequently used information. Thus, this information does not have to be transferred from the disk drives to the processor again with the help of RAM, which ensures the overall system performance.

RAM is an energy-dependent component, i.e. As soon as the current stops flowing to RAM, all information from the memory is automatically erased. RAM consists of cells in which information is stored. With each new entry in the cell, the previous information is automatically erased and new information is written. Thus, the more memory capacity of RAM, the more such cells, and therefore more information can store RAM without overwriting and without using a paging file, which reduces the time of delivery of information to the processor, thereby increasing system performance.

It's worth mentioning that the cache memory is essentially super-fast memory, but unfortunately it does not fit large memory arrays and therefore you have to use RAM.


Physically, RAM is circuits and chips that form modules. Modules usually connect to the motherboard. And how they connect correctly you will learn from the following articles on the site. Therefore, stay with us and subscribe to publications so as not to miss our next articles.
