UDP
User Datagram Protocol is similar to TCP/IP but unlike TCP it does not provide
error recovery methods if the message was not received correctly. Because it is
essentially a one way method of sending data it is primarily used to broadcast
messages over a network.
See RFC768.
Uplink Port
Many hubs will have one uplink port where you can attach a cable to another hub
to share interfaces. If this is the only port available on your hub you can indeed
use it but you will need to connect a crossed cable to use it.
Upload
To copy data (such as a file) from a local source to a remote destination. Usually
referred to as the action of the recipient when putting or sending data to another
device or computer. When you copy a configuration file from your computer to
your router you are uploading the data to your router.
URL
The Uniform Resource Locator is the global format to access documents and
resources on the Internet. A URL uses three parts to reach a specified resource or
file. The first part of the address describes the protocol to be used (such as http or
ftp), the second part identifies the IP address or domain name of where the desired
resource is located (www.mycompany.com). Finally the name of the resource or
file is added. A complete url to reach a web page may look like this
http://www.mycompany.com/storefront.html.
Users
User accounts on the MultiCom Firewall allows up to 10 different users to be
configured with usernames, passwords and administrative privileges. These
Users will be allowed access to the MultiCom Firewall for configuration and data
access purposes (from http, https, telnet, ssh, and ftp.) These accounts are not
related to PPPoE or PPTP accounts.
VC
Virtual Circuit Multiplexing is one of 2 different methods for encapsulating data
over a DSL connection. The other method is LLC.
