Glossary

10/100Base-T Ethernet which uses unshielded twisted pair (UTP - CAT 5, CAT 5e, CAT 6) cable, where the
amount of data transmitted between two points in a given amount of time is equal to either
10 Mbps or 100 Mbps.
1000Base-T, gigabit Ethernet
An Ethernet standard that transmits at 1 Gbps over twisted pair wire.
Custom Web page Any file that can be loaded into an IPCP and served by the internal Web server. The IPCP
can be used for various Web-based tasks. The Web page provides a way to control the
IPCP and other devices attached to it without use of the software, and with or without an
accompanying event script. Any number and size of graphics can be used. If they are too
large to fit in the nonvolatile memory of the IPCP, Web pages can be created so that they
can be served from another Web server using Microsoft Internet Information Services (IIS).
DHCP (Dynamic Host Configuration Protocol)
A standardized client-server communications protocol that enables a server to automatically
assign unique network addresses (IP address, subnet mask, gateway) to a device using a
defined range of numbers configured for the network.
DNS (Domain Name System)
DNS is the application layer protocol that locates and translates an Internet domain name
(such as www.extron.com) into a numerical Internet Protocol (IP) address. A domain name is
an easy-to-remember "handle" for an Internet address.
Driver A software package that controls the interface between the control processor and peripheral
devices.
Ethernet A network protocol that uses MAC addresses instead of IP addresses to exchange data
between computers. Using ARP (see above) with TCP/IP support, Ethernet devices can
be connected to the Internet. An Ethernet LAN typically uses unshielded twisted pair (UTP)
wires. Ethernet systems currently provide transmission speeds of 10 Mbps, 100 Mbps (fast
Ethernet), or 1000 Mbps (gigabit Ethernet).
FTP (File Transfer Protocol)
A protocol that is used to transfer files from one host to another host over a TCP-based
network (such as the Internet). Also see Secure File Transfer Protocol (SFTP) for the version
that incorporates security features.
HTTP (Hypertext Transfer Protocol)
A network protocol based on TCP/IP that is used to retrieve hypertext objects from remote
Web pages and allows servers to transfer and display Web content to users.
HTTPS (Hypertext Transfer Protocol Secure)
A communications protocol for secure communication over a computer network. It allows
Web servers to transfer and display Web content to users securely. All transferred data
is encrypted so that only the recipient is able to access and read the content. It is not a
protocol, itself, but rather a combination of Hypertext Transfer Protocol (HTTP) on top of
the SSL/TLS protocol, which adds the security capabilities of SSL/TLS to standard HTTP
communications.
