Bridge (1) A component used to attach more than
one I/O unit to a port. (2) A data communications
device that connects two or more networks and
forwards packets between them. The bridge may
use similar or dissimilar media and signaling
systems. It operates at the data link level of the OSI
model. Bridges read and filter data packets and
frames. Facilitates communication with LANs, SANs,
and networks with dissimilar protocols.
Bridge/Router A device that can provide the
functions of a bridge, router or both concurrently. A
bridge/router can route one or more protocols, such
as TCP/IP, and bridge all other traffic.

elements.
C
Channel (1) A path along which signals can be
sent; for example, data channel and output channel.
(2) A functional unit, controlled by the processor, that
handles the transfer of data between processor
storage and local peripheral equipment.

Client authentication The verification of a client in
secure communications where the identity of a
server or browser (client) with whom you want to
communicate is discovered. A sender's authenticity
is demonstrated by the digital certificate issued to
the sender.
Client-server relationship Any process that
provides resources to other processes on a network
is a server. Any process that employs these
resources is a client. A machine can run client and
server processes at the same time.
Cluster A type of parallel or distributed

Common Internet File System
open cross-platform mechanism for client systems
to request file services from server systems over a
network. It is based on the SMB protocol widely
used by PCs and workstations running a wide
variety of operating systems.
Console A user interface to a server.
