FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Sequential Access. The standard method for accessing files and devices is the sequential method. It can be like a cassette tape that rewinds itself after every use.

Detailed explanation-2: -Cassette tapes, for example, are sequential access media: You have to ‘go through’ the first 10 minutes if you want to listen to a piece which begins at the 11th minute of the tape. The most common type of secondary storage medium is the magnetic disk.

Detailed explanation-3: -A common example of sequential access is with a tape drive, where the device must move the tape’s ribbon forward or backward to reach the desired information. The opposite would be RAM (Random Access Memory) going anywhere on the chip to access the information.

Detailed explanation-4: -The tape is a sequential-access medium, which means that it may require a comparatively lengthy time to locate a specific piece of data. The information on tape can be arranged in several ways. The earliest approaches used linear multitrack recoding, illustrated in Fig.
