Cloud Storage is actually an online storage when users can store their media like photos,videos and files online. Data is stored on a multiple server. Besides that, cloud storage also helps users to backup their files easily so that they can access it online. Files that are uploaded on the interent can be shared to other users as well. Cloud storage is very useful because if the internal memory of an electronic devices is damage, the photo can still be recovered via the cloud storage. Cloud storage also offers extra storeage if users are able to perform certain task that are given.

The second feature that is offer by Dropbox is additional space that are given when users perform a task.
The third feature, the files that are on the drop box can be shared to other users that are using this feature as well.
PART 2
How does hard disc write and read datas?
Hard disc write datas using the arms that move and reads items and writes items and writes items in
the drive. The operations of these components are controlled by a circuit board mounted inside the disk casing. This circuit board governs a number of things, including the speed at which the spindle motor turns and the actuator controlling the movements of the head arm.
The hard disk needs to link in with the rest of the PC's circuitry; hence, there's also a hard-disk controller acting as the interface to the rest of the PC system. With older hard disks, such controllers took the form of a card occupying one of the PC's expansion slots. Hard disk controllers are always integrated into the motherboard.
The data on the hard disk's platters is stored in a number of concentric circles, known as tracks. A track is divided into smaller areas called sectors, each one of which can store 512 bytes of data: a 40GB hard disk thus contains around 80 million sectors. However, if your data were stored in 512-byte chunks it would make the hard disk job of finding it, reassembling it and loading it into your PC's memory an extremely inefficient one.
Five different storage.
Flash Memory
1)
2) Cloud Storage
4) Tape
5) Microfilm and Microfiche
