Transaction file: It stores the input data until the application uses it during next processing cycle. b. Master file: It contains all current data relevant to an application. c. Output file: some applications use multiple programs. One program takes the output of another program as input; hence the former program stores the output as an output file. d. Report file: It is a copy of report, generated by application in computer accessible form. e. Backup file: It is a copy of file crated by user or system to avoid loss of data due to corruption or deletion of original file.

Four basic service provided by internet to its users are electronic mail, file transfer protocol, telnet and use net news. The common network types are personal area networks (PANs), local area networks (LANs), metropolitan area network (MANs), campus area networks (CANs) and wide area network (WANs).

4. What is a secondary storage?
The additional memory needed in all computers to overcome the limitations of primary storage (Limited capacity and Volatile) is called secondary is nonvolatile and has lower cost per bit stored. It operates generally at slower speed than primary storage. Computer system uses it primarily to store large volume of data on permanent basis. Commonly used storage devices are hard disk, CD ROM, DVD, memory card and Pen drive.
