The answer is sequential<\/strong>.<\/p>\n Sequential access is a data access method where data is accessed in a linear order, one record after the other. This is the simplest and most efficient way to access data when all of the data needs to be processed.<\/p>\n Indexed access is a data access method where data is accessed using an index. An index is a data structure that maps keys to data records. This allows data to be accessed in a non-linear order, which can be more efficient than sequential access if only a small subset of the data needs to be processed.<\/p>\n Direct access is a data access method where data is accessed directly by its address. This is the most efficient way to access data, but it requires that the data be stored in a specific way.<\/p>\n Random access is a data access method where data can be accessed in any order. This is a more general term than sequential access or direct access, and it can refer to either of those methods.<\/p>\n In the case where one has to process all the data records in a file, the best file organization is sequential. This is because sequential access is the most efficient way to access data when all of the data needs to be processed.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Indexed” option2=”sequential” option3=”direct access” option4=”random access E.
