What is the sequential approach?

Sequential Access is a system by which the stored data is accessible in a fixed order. One example is audio or video tape. The most common use of the sequence approach of the phrase is in the computer memory where it contrasts with the widely used accident memory. Likewise, this order is determined, it is predetermined and monitors the logical procedure. Some types of sequential approach are inevitable, for example when playing a cartridge. Other types are a deliberate choice. This may include computer data stored as a linked list in which each piece of data contains a link to the following piece.

Sequential Access Memory is a storage system where the data is stored and read in a fixed order. This is in contrast to the memory with random access, such as those used by computers to process data. As a rule, the sequential approach of the memory type is more likely to be used for permanent storage of ENT storage and random access for temporary storage. Hard drives are also sequential,rather than memory with a random approach. Memory with random access included memory chips found on computers, as well as flash memory, which can be repaired inside the device or removable, such as memory sticks or memory cards.

The main advantage of the sequential, unlike the memory of random access, is that it is usually much cheaper to produce. This also allows you to get more data capacity with respect to the set price and the set physical size limit. Sequential access memory is also used more often in forms of physical storage, which are less sensitive to physical damage, including electric increase or energy loss.

The main disadvantage of this type of memory is that physically, it usually takes to resist any piece of data. This is because the computer must either go through all the data in order until it finds the right piece like searching information in a book without an index or must POut the SEEK function that knows where the data is stored, but must still be physically moved to the appropriate part of the storage device. On the other hand, a random access memory is set, so it usually takes the same time to find any piece of data.
