The computer's random access memory is necessary for the temporary storage and processing of information, for the operation of processes and applications. The more RAM you have, the faster your computer runs.
If we talk about computer memory, we can distinguish two types - operational and external (permanent). External memory does not depend on whether the computer is turned on or not, and the RAM is "zeroed" when it is turned off. It is called volatile.
RAM and read-only memory
Random access memory can be defined as the temporary memory of a PC that works when the computer is turned on. It is necessary for the uninterrupted operation of processes and programs. When the computer is turned off, the RAM is empty. But the permanent memory will store information on the medium until the user deletes it, or a physical violation of the recording layer occurs.
The speed of the computer depends on the amount of RAM.
What is RAM for?
To make it clear what RAM is for, one simple process can be disassembled. So, you open the folder with the word document and start making changes to it. After working for half an hour, we received a modified document. You see it on the screen, but in fact it only exists in RAM. If the computer is turned off, the document may disappear.
In order for the modified file to be available the next time the computer is turned on, it must be saved to permanent memory. For example, in the folder "My Documents". In this case, the RAM will be freed up.
When the game process takes place on the computer, the RAM is constantly working. It is in it that the previous moves of the character, for which the user is playing, are stored. Game developers try to provide for saving the passed levels in permanent memory so that the gamer can return to the interrupted game at a certain level without starting it over.
The amount of RAM depends on the number of processes and programs that can run simultaneously without freezing. So, when you run a large number of programs that require a considerable amount of RAM, the computer will start to malfunction. This indicates that the memory is full and several applications need to be closed. Sometimes only restarting the computer helps.
Currently, users are trying to have 2 GB or more RAM. Although ten years ago it was considered good to have a computer with 512 MB of RAM. Surely in the coming years, personal computers with 20 GB of RAM and higher will be produced.
