A memory that can be read and write and is volatile is known as

A memory that is volatile, meaning that it loses its contents when the power is turned off, and can be read and written to is called Random Access Memory (RAM). RAM is a type of computer memory that is used to store data and programs that are actively being used. The contents of RAM can be easily changed, and it is a fast type of memory that allows the computer to access data quickly. However, because it is volatile, any data stored in RAM is lost when the power is turned off. In contrast, Read-Only Memory (ROM) is a type of memory that is non-volatile, meaning that its contents are permanent and cannot be changed. EPROM (Erasable Programmable Read-Only Memory) and EEPROM (Electrically Erasable Programmable Read-Only Memory) are types of non-volatile memory that can be reprogrammed, but they are not as fast as RAM and are not used for actively storing data and programs.
