WHAT ARE THE SECONDARY STORAGE DEVICES IN A COMPUTER?

 Computers always need a storage device. They use these devices to store different data in them. Now things are moving towards a digital world. Scientists are tiring to convert everything on computers. For this purpose computers are using these devices to store data. One can not live without having a technology's panorama in real world. One can find the details of computer memories here. In early times, people were using different internal and external devices for this purpose. Now scientist have converged things into a very simple things. There are several types of secondary storage devices in a computer. They include Hard Disk, Optical Disks, Flash and Solid State Memories, Smart Cards and Cloud Storage.

While explaining, Secondary Storage is all data that is not currently in computer's primary storage. However, computers can use them according to the need of time. The most important one is called as Hard Disk Storage. These devices are thin but rigid metal glass or ceramic platter covered with a substance that allows data to be held in the form of magnetized spots. There are different sectors in a hard disk. Moreover, this is the most popular type of storage in a computer. Whereas Optical Disks are preferred medium for music, movies and software programs because of its advantage. They are compact , light weight, durable and digital. The example of them lie in CDs, DVDs, and Blu-ray. It is important to tell that computers use different types of CD and DVD players to read optical devices. Another thing about optical disk lies in that they have limited storage capacity than hard disk. Flash and Solid State Memory have become the most important form of mobile storage. They also have the limitation of storage capacity. They have a built in system to read and write data in a device. Smart Card is  pocket size card with integrated chips. Moreover they need a card reader so that devices can read the data from them. Computer attach these readers using  using a USB port to them. They also have a limited storage capacity in them. Cloud Storage has become the most important type of storage in todays time. People prefer this that they store their data on online portals so that no one can access it. Different companies are providing different solutions regarding online storage. The most important one lies in Google drive storage.

In a nutshell, it can be said that computers are using different storage devices for their use. These secondary storage devices store data for backup. It means that people can access them for their use. The most important one lies on Google drive.
