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
