storage devices

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).

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.
