client-server model
A common way to describe network services and the model user processes (programs) of those services. Examples include the name-server/name-resolver paradigm of the DNS and file-server/file-client relationships such as NFS and diskless hosts.

CLNP
Connectionless Network Protocol. The OSI protocol for providing the OSI Connectionless Network Service (datagram service). CLNP is the OSI equivalent of Internet IP, and is sometimes called ISO IP.
CLNS
ConnectionLess Network Service
CLTP
Connectionless Transport Protocol. Provides for end-to-end Transport data addressing (via Transport selector) and error control (via checksum), but cannot guarantee delivery or provide flow control. CLTP is the OSI equivalent of UDP.
Common Management Information Protocol. The OSI network management protocol. The IP network management protocol is SNMP.

CODIAC
CODIAC is a data management system which offers scientists access to research and operational atmospheric data. It provides the means to identify data sets of interest, view associated metadata, browse the data, and then automatically obtain data via Internet file transfer (FTP).
An FDDI device that localizes connections to an FDDI ring.
connection-oriented
The model of interconnection in which communication proceeds through three well-defined phases: connection establishment, data transfer, connection release. Examples: X.25, Internet TCP and OSI TP4, ordinary telephone calls.
connectionless
The model of interconnection in which communication takes place without first establishing a connection. Examples: Internet IP and OSI CLNP, UDP, ordinary postcards.
CONSOLE PORT MODE switch

switch next to the CONSOLE port on Cisco Catalyst 6500
Surevisor modules. The official positions are either "in" or
"out". When set to the "out"
position you'll see the white. 6500's ship "in", or depressed, as factory default.
