Different Types of storage devices reposition devices can either be magnetic or optical Magnetic Backing Storage devices unverbalised DisksHard Disks argon norm tout ensembley found inside computer. They decimate a biggish capacity which allows large programs to be stored as well as large files (eg a multimedia scan with sound and video). A hard record book consists of of pie-eyed account plates that have been magnetized, and each hard drive usually contains some(prenominal) criminal records stacked on top of each other. These disks are pretty quick as they spin around. The read and write dots foul up above the disks on nothing more than a break down of air. They are so close that a speck of frame would ruin the hard drive. This would be preferably serious, because if there is a problem with the hard drive, all of the data stored on it may be lost, Floppy DisksThe most common external sanction store is a 3.5 inch floppy disk. Floppy Disks all hav e small capacities (1.44 Mb) and are fairly slow scarce they allow files to be taken from unrivaled computer to another. The disk inside the casing a circular cut of magnetised plastic. Because it is floppy, it gets easily damaged. A floppy disk works quite similarly to a hard disk. The read and write outlet actually makes contact with the circular disk, thus reducing the care span of the disk TapeMagnetic tape is often employ when large amounts of data need to be backed up. This government place that tape is often used to backup data so that if a disk crashes then there is a endorsement copy of the data which can be recovered onto a new disk. Tapes are not useful for data which is beingness constantly used because the actual tape could be 100s of metres broad and it would take a long time to get from cardinal end to another. The access time is slow, because the read and write soul cant go directly to a special(a) piece of data, it has to wind through th e whole tape. This is known as serial public! ation or sequential access. Zip DisksZip Disks are larger and thicker than everyday floppy disks, but they work in...If you demand to get a full essay, order it on our website: BestEssayCheap.com
