MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -» Magnetic tape is divided horizontally into tracks (7 or 9) and vertically into frames. A frame stores one byte of data, and a track in a frame stores one bit. Data is stored in successive frames as a string with one data (byte) per frame.

Detailed explanation-2: -Magnetic tape is a storage medium that has provided a viable option for storing, archiving, or backing up data from large computer systems.

Detailed explanation-3: -Tape is a narrow strip being magnetized on one side of the strip. To store data, the narrow strip goes through below the magnetic head which stores the data into bits. Various data are stored on the strip. It helps in storing digital information.

Detailed explanation-4: -Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track, later 9-track tape.

Detailed explanation-5: -In magnetic tape only one side of the ribbon is used for storing data. It is sequential memory which contains thin plastic ribbon to store data and coated by magnetic oxide. Data read/write speed is slower because of sequential access. It is highly reliable which requires magnetic tape drive writing and reading data.
