ans will be C     X.25

Uses of X.25

X.25 is a mechanism for transferring transparent data. Standards exist for encapsulation of higher-level data such as TCP/IP or SNA traffic over X.25. One of the largest uses of X.25 is the transfer of asynchronous data streams such as those produced by simple terminals like credit card readers. These devices connect to a Packet Assembler/Disassembler (PAD) that organizes the asynch data streams into X.25 packets for transmission across the network. PAD design is based on ITU standards X.28, X.29 and X.3.
