which memory
can not save data when computer is shut down
Answers
Explanation:
known as VOLATILE memory. ROM stands for READ ONLY MEMORY and is non-volatile memory. When the computer is shut down the data remains stored. If a computer doesn't have enough RAM is can use a portion of its HARD DRIVE as memory, this is known as VIRTUAL memory.
Random Access Memory (RAM) cannot save data when computer is shut down.
More About RAM (From Internet):
RAM (Random Access Memory) is the internal memory of the CPU for storing data, program, and program result. It is a read/write memory which stores data until the machine is working. As soon as the machine is switched off, data is erased.
Primary Memory
Access time in RAM is independent of the address, that is, each storage location inside the memory is as easy to reach as other locations and takes the same amount of time. Data in the RAM can be accessed randomly but it is very expensive.
RAM is volatile, i.e. data stored in it is lost when we switch off the computer or if there is a power failure. Hence, a backup Uninterruptible Power System (UPS) is often used with computers. RAM is small, both in terms of its physical size and in the amount of data it can hold.
RAM is of two types −
Static RAM (SRAM)
Dynamic RAM (DRAM)
