What do a secondary storage do in a computer?
It helps you to get to know how to use the data storage.
Unlike primary storage; secondary storage is not directly accessed by the CPU. Examples of secondary storage are hard drives, CD/DVD drives, flash, etc. Anything that can store data without losing it upon power down (non-volatile storage) is considered secondary storage. I believe you can tell why it's a necessary component of a personal computer. Without it we would have no place to store our data.
Well, the categories which storage devices are under, are PRIMARY and SECONDARY storage. Primary storage is elctronic storage which is directly connected to the computer. Unlike the primary storage, the secondary storage is not directly connected to the CPU. But, te secondary has more advantages and one big disadvantage which was just mentioned.
storage refers to the keeping of data and information for later. in computer science there are two types of storage that is primary storage and secondary storage in primary storage data is kept temporary in ROM(read only memory) while in secondary storage data is kept permanently like on hard disk, tape, cds.
