Glossary

Workstation: Traditionally a dumb terminal connected to a host. However, with the advent of LANS and WANS, PCs that are connected to a LAN are now called workstations too, even though they are capable of independent process- ing. A workstation is simply an input/display device through which a user accesses a resource.

X

X.121: CCITT’s recommendation for unique addressing of each DTE connected to a communications network through- out the world. X.121 uses fifteen digits: a one-digit prefix, a four-digit DNIC number (which identifies the country and PDN), and a ten-digit national terminal number.

X.21: CCITT’s recommendation for a 15-pin, digital inter- face. It is not widely accepted, because of the analog loops still prevalent in data communications. For this reason, CCITT introduced the X21bis standard for use with synchro- nous modems.

X.25: CCITT’s definition of a three-level packet-switching protocol to be used between packet-mode DTEs and network DCEs. X.25 corresponds with the lower three/four layers of the seven layer OSI model.

X.28: CCITT’s definition of asynchronous commands used by a local ASCII terminal to configure an X.25 PAD.

X.29: CCITT’s definition of packetized commands sent to configure a remote PAD via an X.25 link.

XModem: A widely used asynchronous file transfer proto- col. Programs typically use both the older version, checksum, and the new version, CRC method, to detect errors. If CRC is not present at the other end of a file transfer, then it will use checksum.

Y

YModem: An asynchronous file transfer protocol that improves speed by transmitting 1,024-byte (1K) blocks and batch file transfer.

Z

ZModem: An asynchronous file transfer protocol that is more efficient than XModem. It sends file name, date and size first, and responds well to changing line conditions due to its variable length blocks. It uses CRC error correction and is effective in delay-induced satellite transmission.
