What is the difference between a sequential access file and a random access file?
Furthermore, what is sequential file 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.
Also, which 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) that can go anywhere on the chip to access the information.
Also question is, which function allow to access a file in a non sequential or random mode?
Answer: The Random Access data file is the function which allows us to access a file in non sequential or random mode.
