How would you use data in a sentence?
HDD, Compact Discs, Pendrives are used to store data, and data is all kind of digital informations that you can keep stored to open further.
What is the capacity size of DVD?
Anything from 1.46GB to 17.08, Blu-ray discs can store 25 or 50 gigabytes of data.
What is the difference between Cds DVDs and Blu ray discs?
CDs, DVDs and BluRay discs all work in similar ways. The primary difference is the data density on each disc. CD is the lowest density. A DVD can store several times the amount of data on the same surface area and BluRay will store several time the amount of a DVD.
Is CD sequential or random device?
Yes CD is a sequential strage device. bcoz data store in CD in the form of sequence means we can store data in CD one by on track. we cant jump on different no. of tracks to store data. if we store data in track 1 then another data can store in track 2 not directly 3 or 5.
Increase data transfer speed in 32gb flash drive?
i feel sorry for you
Can you make data dvds with blank Blu Ray Discs?
You can indeed make Blu-Ray discs that hold 35 GB of data or more.
What are the similarities of a floppy disk and a hard disk?
In their basic form, floppy discs are common hard disks are the same technology. They both use magnetism to store and read data. They both use a spinning platter read by a horizontally moving read head. The key differences are that hard disks have the data and reader in the same package, this is why hard discs have evolved in storage capacity while floppy disks remained the same. It was necessary for the written layer of a floppy disk to have the same data density and dimensions as they had to be compatible with floppy disk drives. However with hard discs the drives and read heads could evolve along side the data layer. Hard discs now have metal platers, and store data at a much higher density. The speed of the mechanisms are much much faster. New technologies such as perpendicular storage can be added and have no impact on compatibility.

What are the functions of hard disks?
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
How is data stored on hard discs?
by a magnetic code or ram
