What is an example of sequential access device?

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.

What do you mean by sequential access?

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. Sequential access is sometimes the only way of accessing the data, for example if it is on a tape.

Can a data type be used for sequential numbering?

We cannot just use the auto-number data type because there is no promise of sequentiality but only uniqueness. In other words, if someone creates a record then later deletes it, there will be a gap in the sequence. So, what are our options? There are actually several ways, each with its pros and cons. 1.

Why do I get a sequential number for each record?
