What is the difference between direct access and sequential access?
, Both terms "direct access" and "sequential access" as you must have guessed refer to accessing schemes in the file system. In broadest sense difference between these two can be stated like this -In sequential access data is stored at random locations. -In direct access data is stored at sequential locations. ( Ironically this is true No matter what kind of first impression we get when we hear it for the first time. ) -In sequential access addition of data is fast but retrieval of data is slow. -In direct access addition of data is slow as reordering of data blocks may be needed to put current data block after the last used data block for the file. But retrieval of data is fast. -Data structure implementing Sequential access is linked list. -Data structure implementing Direct access is an Array. Application areas:- A situation where rate of addition of data is much larger compared to retrieval of data Sequential access is preferred, in opposite situation Direct access is more suitable. Regards, Prime There are technical explanations as to how it works, but in simple terms, direct access means going straight to the record you want, whereas sequential access means going through all records one by one until you find the one you want.

File access methods explain?
A serial access file has data stored on it in the order in which it was written. Each new record goes at the end of the file. To read a record from the file it is necessary to read through all the preceding records first.A sequential access file has data stored on it in the order of the data in a key field.A direct access file is one where any record can be accessed without having to access other records first. This is also known as random access.
