SRAM gives fast access to data, but it is physically relatively large. Once a flip-flop stores a bit, it keeps that value until the opposite value is stored in it. What is an example of sequential access device?Ī 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. Other articles where static random-access memory is discussed: computer memory: Semiconductor memory: Static RAM (SRAM) consists of flip-flops, a bistable circuit composed of four to six transistors.

Indexing into a list that has sequential access requires O(n) time, where n is the index. The canonical example is the linked list. In data structures, a data structure is said to have sequential access if one can only visit the values it contains in one particular order. What is the characteristic of sequential access method? A disk drive, on the other hand, is a random-access device because the drive can access any point on the disk without passing through all intervening points. What are the example of sequential access?įor example, a tape drive is a sequential-access device because to get to point q on the tape, the drive needs to pass through points a through p. What are direct access devices give example?Ī direct-access storage device (DASD) is another name for secondary storage devices that store data in discrete locations with a unique address, such as hard disk drives, optical drives and most magnetic storage devices. Sequential access is sometimes the only way of accessing the data, for example if it is on a tape. Sequential access is a term describing a group of elements (such as data in a memory array or a disk file or on magnetic tape data storage) being accessed in a predetermined, ordered sequence.
