Solution

The correct option is E Magnetic tape

Magnetic tape is used for serial access storage only.

Magnetic tape provides serial access. This is in contrast to random access memory (ram) where data can be accessed any order. The data is stored in order on the tape, computing, sequential access memory (sam) of storage devices that read sequence.

Magnetic tape data storage is a system for storing digital information on magnetic tape using digital recording. Modern magnetic tape is most commonly packaged in cartridges and cassettes. The device that performs writing or reading of data is a tape drive. Autoloaders and tape libraries automate cartridge handling.

Magnetic tape is a long and narrow strip of plastic that thin magnetic material is coated on. Nearly all recording tape is of this type, whether used for recording audio or video or computer data storage. Magnetic tape recording uses magnetic tape which moves on a recording head.
