the actual delivery of the data (routing), UDP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for effi-
cient delivery over the network. UDP is known as a "connection-less" protocol
due to NOT requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet (as opposed to TCP).
Upgrade - To replace existing software or firmware with a newer version.
Upload - To transmit a file over a network. In a communications session,
upload means transmit, download means receive.
URL (Uniform Resource Locator) - The address that defines the route to a file
on the Web or any other Internet facility. URLs are typed into the browser to
access Web pages, and URLs are embedded within the pages themselves to pro-
vide the hypertext links to other pages.
VPN (Virtual Private Network) - A technique that allows two or more LANs to
be extended over public communication channels by creating private commu-
nication subchannels (tunnels). Effectively, these LANs can use a WAN as a
single large "virtually private" LAN. This removes the need to use leased lines
for WAN communications through secure use of a publicly available WAN
(such as the Internet). Examples of VPN technology are: PPTP (Point to Point
Tunneling Protocol), L2TP (Layer 2 Tunneling Protocol), and IPSec (Internet
Protocol Security).
VPN endpoint - VPN end point capability within a router provides the ability
to initiate a VPN tunnel to some other location that supports either a VPN client
or has VPN end point capability.
WAN (Wide Area Network)- A communications network that covers a rela-
tively large geographic area, consisting of two or more LANs. Broadband com-
munication over the WAN is often through public networks such as the tele-
phone (DSL) or cable systems, or through leased lines or satellites. In its most
basic definition, the Internet could be considered a WAN.
WINIPCFG - Configuration utility based on the Win32 API for querying,
defining and managing IP addresses within a network. A commonly used util-
ity for configuring networks with static IP addresses.
Workgroup - Two or more individuals that share files and databases.
