Answer 2

Answer:

The option that explains the sequential

file access methods is,

(C) Read/write sequentially by records

Explanation:

• Sequential file access methods are the easiest ways to access. Just like the term reads, the records are read in a sequential manner.
• When one record is read and accessed, control moves on to the next record in order to read and access it.
• This method of sequential file access is one of the most primitive ways or techniques to access file especially used by editor and compilers for the process of access.

Hence, the option that explains the sequential file access methods is,

(C) Read/write sequentially by records
