block definition
record contain clause
blocking factor
record per block factor E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is: C. blocking factor.
A blocking factor is the number of logical records that are grouped together to form a physical record on a magnetic tape. The blocking factor is specified by the user when creating a file on magnetic tape. The blocking factor affects the efficiency of data access on magnetic tape. A higher blocking factor results in more efficient data access, but it also results in larger files. A lower blocking factor results in smaller files, but it also results in less efficient data access.
The other options are incorrect.
- A block definition is a set of parameters that define the structure of a block of data on magnetic tape. The block definition includes the number of bytes in the block, the number of records in the block, and the format of the records.
- The record contain clause is a clause in a COBOL program that specifies the number of records that are contained in a block of data on magnetic tape.
- The record per block factor is a factor that is used to calculate the number of records that are contained in a block of data on magnetic tape. The record per block factor is calculated by dividing the number of bytes in the block by the number of bytes in a record.
- None of the above is a correct answer.
