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.

What is difference between sequential file and index file?
the index file is more sicurity checked and contains more information about the acess . for example An indexed file is a computer file with an index that allows easy random access to any record given its file key.The key must be such that it uniquely identifies a record. If more than one index is present the other ones are called alternate indexes.The COBOL language supports indexed files with the following command in the FILE CONTROL section. however a sequential file isA file that contains records or other elements that are stored in a chronological order based on account number or some other identifying data. In order to locate the desired data, sequential files must be read starting at the beginning of the file. A sequential file may be stored on a sequential access device such as magnetic tape or on a direct access device such as magnetic disk. Contrast with random-file.Read more: sequential-fileContent of sequential file can't be accessed directly while index file content can be accessed directly through pointer. Sequential file is time consuming in comparison with index file.Example: Index of book - index fileExample: Bundle of plates - sequential file
What is the difference between the file maintenance and file organization?
file organization is of 3 types sequential,direct and indexed sequential where how data is accessed in eash file is decided where as file maintainence is
Difference between direct sequential file and index sequential file?
Explain the difference between sequential and direct file access.A. Sequential access to data is used when the data has to be read from the start, in sequence. It is the normal method of access for magnetic tape. Direct access is used when it is possible to jump directly to a file or data item without reading through all the items stored before it. This is the normal method used for hard disks.

Implementation of index sequential file organization?
Indexed sequential file organization. =In indexed sequential file organization, the records arestored in sequence according to a primary key and an index is created to allow random access of the file. This type of organization also allows the file to be accessed sequentially. Indexed sequential is the most commonlyused type of file organization. writer-k.k.b -montanna
Difference between sequential organization and serial organization?
the difference is that sequential organization: this are records are stored and accessed in a particular order sorted using a key field serial organisation: records in a file are stored one after another. You need to go first file in order to reach the required file.
Difference between sequential file and serial file?
These lecture notes describe those file organizations in detail and compares and contrasts them: http://www.cim.mcgill.ca/~franco/OpSys-304-427/lecture-notes/node53.html
What is a indexed sequential file?
An indexed sequential file is a type of file organization where data records are stored sequentially in the order of key values. An index is maintained to help locate records quickly. This combination of sequential storage and indexing allows for efficient access to data in both sequential and random access patterns.
What is difference between sparse index and dense index?
Dense Index: An index record appears for every search key value in file. This record contains search key value and a pointer to the actual record. Sparse Index: Index records are created only for some of the records. To locate a record, we find the index record with the largest search key value less than or equal to the search key value we are looking for. We start at that record pointed to by the index record, and proceed along the pointers in the file (that is, sequentially) until we find the desired record. - - (ref: http://sawaal.ibibo.com/computers-and-technology/difference-between-sparce-index-dence-index-773764.html)
What are sequential access files?
The file(s) (data) which are accessed in a sequential or a orderly manner is called as a sequentially accessing a file.
Which file organization is most efficient for a file with a high degree?

Advantages of sequential file in c?
You don't have to bother with positioning in the file.
