![]() ![]() ![]() Secondary storage devices have numerous types. In this way, even if power is lost and all of the data on the primary storage has been lost, the user will still be able to recover the last saved version of the concerned file. However, in the presence of a secondary storage device, data will be saved as long as it has neither been deleted nor overwritten. In such situations, the user won’t be able to access or store its data for the retention period of his/her choice. Primary storage is basically a volatile type of memory where data is lost if the power goes off. The reason why second storage is so important lies in the volatile nature of the primary storage. Generally, secondary storage technology is about two orders of magnitude cheaper than the primary storage. Besides that, it is also used as a backup storage medium just like cloud storage to protect from data loss due to computer malfunction, cyber-attack or any other tragedy. It must be noted that the prime function of the secondary storage is to compliment the primary storage. It is also known as auxiliary storage, external memory, flash memory, and secondary memory. Secondary storage is a non-volatile memory, which has the capability to hold data until and unless it has either been deleted or overwritten. Random-Access Memory (RAM) and cache memory are examples of a primary storage medium. ![]() Primary storage stores data for a short time frame when a computer is running. Storage in a computer is referred by two terms, i.e. From storing important data to playing the heavy-duty games, all this is possible due to the huge storage mediums. One of the prime features of today’s computer is its capability of storing huge amounts of data. But with the developments in technological avenues, computer systems are now much more functional and handier. Owing to their huge size and complex architecture, no one ever thought to use them for data storage purposes. ![]() Secondary storage -In old times, computers were used to solve complex problems. ![]()
