Whereas Secondary Memory is Volatile i.e. Primary memory has limited storage capacity. Data to be permanently stored is kept in secondary memory. "@type": "Answer", The difference between primary memory and secondary memory is that primary memory is considered as the main memory of the computer that can be accessed by CPU. Secondary memory stores the data permanently; even if you have switched off the power, it doesn’t lose the data. A computer can work without a secondary memory but not without a primary one. It is also used for small, portable, and remote computer storage devices. An example of Primary memory is RAM and ROM that store programs. 1. Computer memory is categorized into primary and secondary memory. "@type": "Answer", Primary memory is usually volatile. After shutting down the power the data automatically gets deleted. Thus, Secondary Memory used to store data and files permanently. The faster the speed of turns, the faster it can store or read data. And that’s why it is known as primary memory. } They are made to replace the floppy disks used to store files and programs from the computer. The Stored programs and files cannot be modified and deleted in this memory, they can only be read. Multi-level hierarchical cache setup is also commonly used—primary cache being smallest, fastest and located inside the processor; secondary cache being somewhat larger and slower. 10.

Difference between primary Memory and secondary Memory ∆Definition of Primary Memory. The data of primary memory is very limited, and the limitation of primary memory is less than secondary memory. The secondary memory is accessible in the form of Mass storage devices such as hard disk, memory chips, Pen drive, floppy disk storage media, CD and DVD. Hence, the system is loaded to RAM or primary memory from secondary memory on the start. This is Permanent memory in which information is entered into it once and stored permanently (even the computer turned on and off). Primary memory stores the data or instructions for quick access and direct access. Secondary memory is used to store data and information on a long-term basis. ", Originally denoting dual- storage memory models prior to its replacement with long-term memory. It is volatile memory, meaning that data is stored temporarily and lost when the power is switched off. The data is then processed by the central processing unit. Secondary memory is used to store data and files on a long-term basis. There is a basic difference between primary and secondary memory in terms of volatility. Primary memory, i.e. RAM- volatile in nature. Its range is from 2 GB to 1 TB. The Stored programs and files cannot be modified and deleted in this memory, they can only be read.
