What is Disk? and how its works?

Overview

Disks are secondary storage devices that can be used to store extended amounts of data. You have a variety of options when selecting a disk as a storage medium.

A hard disk or drive can help boost the performance of your computer. You can use large disks to store programs, images, files, documents, and other data.

Benefits

A backup is essential to maintain a copy of vital data. Storing your information helps you organize your files and documents and retrieve them when required. If any data is lost due to natural disaster or physical damage to the system, you can retrieve data from the backup. Information that is stored in the disk can be accessed easily by anyone at any time. Disks also allow you to communicate and transfer data very easily with others. Using portable disks, you can move data to different physical locations.

How It Works

Disks come have varied functionalities. One type of disk is a floppy disk, which can be inserted directly into the computer. All information that is on your system can be transferred to the floppy and can be removed and stored in a safe place. Data can be written and rewritten on these disks, and you can easily transfer data from one location to another. A major drawback is that you cannot store a large amount of data, and all data will be destroyed when the disk is placed near a magnet.
To overcome these drawbacks, smaller and thicker versions of floppies were developed. This disk allowed people to store more data and was not affected by magnets. These disks also have a locking feature that allows you to lock the information once it is saved. So, no one can change or remove the information stored in these disks. They also come in a number of colors and are easy to carry around.
Over time, the software industry and need for larger storage spaces has grown. As a result, manufacturers have expanded a computer's storage capacity. You can store a large number of pictures, documents, and video files. The drawback is that hard drives are not portable. You cannot carry your data to another location.
To address this problem, developers have created portable hard drives. Portable hard drives are sleep and lightweight and can easily be transported from one place to another. Portable hard drives can also be transferred between computers. These drives can store hundreds of gigabytes. They tend to be expensive, but they keep your information portable and in a secure place.
CDs and USB Flash drives are other portable disks that you can use to store files and backup data. These storage mediums are compact, portable, and durable.
