Because it is volatile, i.e: when the computer looses power, the data will be gone. But, for things like open files, they are stored in the RAM, then when you save them, they get written to a disk of some sort.
Ram
RAM is a primary storage medium, but it is volatile. Cache memories storage frequently accessible data.
use of ram:- use it as primary storage. suppose you put a data into it.ram is the only who save the data for primary time.

ram
RAM is volatile storage that holds the program and data that the CPU would be processing.
RAM is used for short-term storage of data and instructions, ROM is for long term storage of operating instructions. RAM is necessary so you can access any data at any time.
RAM stands for Random Access Memory. It is a form of computer data storage, and stores all of your documents and files on the computer.
The component of a computer that utilizes RAM for temporary storage and quick access to data is the CPU (Central Processing Unit).
read to the file
It is mainly used for temporary storage of data.It is also known as volatile memory. If the system gets turned off,the data stored on RAM gets erased.
Paging is a way for the operating system to load data from a storage device onto RAM. When there is insufficient amount of space in RAM and if a page file is enabled, it will swap data between RAM and the swap file (typically on a storage device).
