What Is The Difference Between The Main Storage And The Backing Storage Of The Computer?
2 Answers - Sort by: Date | Rating
The main storage, also called as primary storage or memory is the memory which is directly accessible by the CPU. It includes the data that is being currently used. This memory is connected to the CPU through a data bus and an address bus. It is the RAM of the computer. The data in this memory is volatile which means that it disappears when the power is switch off. On the other hand, a backing storage device is an external memory and has permanent storage. Data is stored in this memory and is not lost on when power is switched off.
