Solution: The secondary memory which allows us to store a large amount of data is often referred to as the auxiliary memory. It generally stores large amount of data on a permanent basis.

Solution: The statement is true as secondary storage devices can store large amounts of data temporarily. It is used to overcome the limitations of primary storage.

Solution: Magnetic tapes are sequential access devices. They are the secondary storage devices and are used to store large amounts of data. In sequential access, data can be retrieved in the same sequence in which it is stored.

Solution: Plastic ribbon is coated with a magnetizable recording material. Iron oxide and chromium dioxide is generally used in magnetic tapes. Data are recorded on the tape in the form of tiny invisible dots.

Solution: The data recorded on the tape is the form of tiny invisible magnetized and non-magnetized spots (representing 1s and 0s) on its coated surface.

Solution: Storage capacity is nothing but the product of length and the data recording density. Magnetic tape is commonly used sequential-access secondary device. Data recording density is measured in bytes per inch.

Solution: Data recording density is the amount of data that can be stored on a given length of the tape. It is measured in bytes per inch. Bytes per inch=bpi.

Solution: Transfer rate measurement unit is bytes/second(bps). Value depends on the data recording density and the speed with which the tape travels under the read/write head.

Solution: Data transfer rate is defined as the number of characters per second that can be transmitted to the memory from tape. The typical value is 7.7 megabytes per second.

Solution: The tape drive is connected to and controlled by a tape controller that interprets the commands for operating the tape drive. Certain commonly used commands are read, write, erase tape, etc.
