Name/Acronym Name/Definition Comments
Telnet
Application that provides a
terminal interface between
hosts using TCP/IP.
Telnet defines a protocol that allows a remote
terminal session to be established with an Internet
host, so that a remote user has can use the remote
host as though he was sitting at a terminal
connected directly to the Host.
Throughput
Data volume transmitted per
unit of time.
Example: 10 Mbps
Token Ring
A network topology in
which the nodes are
addressed and can transmit
in a fixed sequence.
The “token” is a special code that is passed from
node to node in the same fixed sequence. Each
node can hold the token for a limited time, and can
transmit only as long as it holds the token.
Topology
The configuration scheme
for a network.
Types of network topology include Ring, Bus, Star,
and Tree.
UDP User Datagram Protocol
Similar to Transport Control Protocol (TCP), but
less complex regarding reliability features, and
hence, faster than TCP.
Uplink Port
Ethernet Port that enables
inter-connection of
networking devices
Some Hubs and some Switches include an
additional port that enables connection form hub to
hub, hub to switch, etc. Typically, the Uplink Port
is a cross-over connector; on some devices, the
Uplink Port can be configured (or selected) as
either cross-over or straight.
VLAN Virtual Local Area Network
Provides access to multiple IP subnets at a physical
location.
VPN Virtual Private Network
Remote access via a secure (encrypted) “tunnel”
though the Internet.
WAN Wide-Area Network
Typically, a network that includes several LANs at
different geographical locations, interconnected
using common carrier transmission services.
WINS
Windows Internet Name
Service
