Data storage is one of several elementary yet vital functions in our digital world. Data storage is defined by a hierarchy of four levels: primary storage, secondary storage, tertiary storage, and offline. You’re probably most familiar with primary storage and secondary storage, but what do you really know about them? This post will serve as a primer for those who need an introduction or refresher course. So let’s take a look at how primary storage and secondary storage square off in the complex storage landscape. The Main Storage Option
Typically located inside the computer, primary storage temporarily houses applications and data currently in use. Primary storage is often referred to as “memory” and is classified as either volatile or non-volatile. Volatile memory such as RAM loses data as soon as the device loses power. The flash memory in solid-state drives (SSDs) is non-volatile because the data remains in storage even after you have turned it off. That lets some applications recover unsaved information in the event of a crash. Examples of Primary StorageROM PROM Cache memory Primary storage provides fast access to the CPU. That allows active programs to deliver optimal performance to the end-user. Speed and usefulness aside, the loss of power means the loss of data. That makes RAM a short-term storage solution. In fact, its lack of long-term viability is the driving force behind the saying “save often.” From Primary Storage to Secondary StorageDespite their different purposes, primary storage and secondary storage often work together to create ideal storage conditions. For instance, when you save your work in Word, the file data moves from primary storage to a secondary storage device for long-term retention. Likewise, a primary storage device retrieves data from a secondary source to speed up access. Also known as auxiliary storage, secondary storage retains data until you either overwrite or delete it. So even when you turn off the device, all data remains intact. Common Examples of Secondary StorageHard drives Optical media: CDs and DVDs are the most well-known members in the class of optical storage. These mediums are the more efficient successors of the 3.5-inch disk drives. You had to use these in spades to store any substantial amount of data. Optical media have exceptionable read speeds, capacity, and portability. That’s why they are still in use as secondary storage to some degree today, even as better options have come along. Magnetic tape: In use for well over half a century, magnetic tape was once the very foundation of backup systems. Reel-to-reel tapes have evolved into high-capacity tape cartridges, boasting exceptional durability that continues to earn them a place in over half of today’s hybrid data center. Tape is an affordable option for secondary storage and by enabling longer retention periods and reducing storage requirements. Secondary storage is named as such because it doesn't have direct access to the CPU. As a result, it is considerably slower than primary storage. Luckily it compensates for that lack of speed in several ways. Aside from offering greater data retention, secondary storage is usually twice as cheap compared to its primary counterpart. It can also store significantly more information. An 8GB stick of RAM is a decent size, while new computers generally have 1TB hard drives. There is no comparison on capacity. The Cloud: The Best of Both WorldsThe cloud has quickly become the secondary storage medium of choice for many organizations. But with today’s faster connections, the availability of microservices and other technology advances, the cloud is now used more and more frequently as both primary and secondary storage. How your organization uses the cloud depends on many factors that we’ll cover in a future post. Cloud storage’s most apparent benefits are security and availability. With data stored in the cloud, you can expect your data to always be safe and accessible from anywhere. ConclusionPrimary and secondary storage is integral to a comprehensive storage strategy. The former provides fast and efficient access to resources. The latter offers a long-term retention solution for the massive amount of data—documents, photos, videos, and so on—that we accumulate continuously. We sometimes take storage for granted, but the IT landscape could not function without them. What part of memory in which data and program are stored is called?The term storage refers to secondary memory and is where data in a computer is kept. An example of storage is a hard drive or a hard disk drive (HDD).
What is used to store data and programs?Storage devices can include hard disk drives (HDDs), flash-based solid-state drives (SSDs), optical disc drives, tape systems and other media types.
Which type of memory is used to store data and instructions in the computer?1. Primary Memory: It is also known as the main memory of the computer system. It is used to store data and programs or instructions during computer operations.
What is used to store data in memory?SSD and flash storage
Flash storage is a solid-state technology that uses flash memory chips for writing and storing data. A solid-state disk (SSD) flash drive stores data using flash memory. Compared to HDDs, a solid-state system has no moving parts and, therefore, less latency, so fewer SSDs are needed.
