PRIMARY AND SECONDARY STORAGE DEVICES

 

 PRIMARY AND SECONDARY STORAGE DEVICES

 Primary storage and secondary storage are two different types of computer storage.

Ø Primary storage, also known as main memory or RAM (Random Access Memory), is a type of computer memory that is used to store data temporarily. It is much faster than secondary storage and is used to store data that is being actively used by the operating system and applications. When the computer is turned off or restarted, the contents of primary storage are lost.

Ø Secondary storage, on the other hand, is used to store data permanently. Examples of secondary storage devices include hard disk drives (HDD), solid-state drives (SSD), floppy disks, CDs, DVDs, and USB flash drives. These devices provide much larger storage capacities than primary storage and are used to store files, documents, pictures, videos, and other data that needs to be saved and retrieved at a later time.

  In general, primary storage is more expensive per unit of storage than secondary storage, but it is faster and more reliable. Secondary storage is slower than primary storage, but it provides larger storage capacities and is more affordable. To optimize the performance of a computer, it is important to have a good balance between the two types of storage.
