CTS (Clear To Send) - An RS-232 signal sent from the receiving station to the transmitting station
that indicates it is ready to accept data.
Data Packet - One frame in a packet-switched message. Most data communications is based on
dividing the transmitted message into packets. For example, an Ethernet packet can be from 64 to
1518 bytes in length.
Default Gateway - The routing device used to forward all traffic that is not addressed to a station
within the local subnet.
Download - To receive a file transmitted over a network. In a communications session, download
means receive, and upload means transmit.
Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP
network, typically by a DHCP server. Network devices that serve multiple users, such as servers
and printers, are usually assigned static IP addresses.
Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved
from a common transmission medium. Has a transfer rate of 10 Mbps. Forms the underlying
transport vehicle used by several upper-level protocols, including TCP/IP and XNS.
DDNS (Dynamic Domain Name System) - Allows a network device with a dynamic Internet IP
address to have a fixed host and domain name, such as myhostname.mydomainname.com. It is
useful when you are hosting your own website, FTP server, or other server behind a router, so
people can find your site no matter how often the Internet IP address changes. Using DDNS
requires registering with a DDNS service provider on the Internet.
