IP address is a unique, 32-bit, binary number (12 digit decimal number, xxx.xxx.
xxx.xxx) that identifies each device or device port (an information sender
and/or receiver) that is connected to a LAN, WAN, or the Internet. IP
addresses can be static (see static IP) or dynamic (see DHCP).
IP net mask/subnet mask — See subnet mask.
IRCM (Infrared Control Module) is a type of Extron keypad used with MediaLink
Controllers (MLCs) and system switchers. IR commands for source devices
(VCRs, DVD players, receivers) can be stored in the MLC or switcher. After
setup, pressing a button on the IRCM causes the controller or switcher to
send a command to the source device.
MAC (Media Access Control) Address is a unique hardware number given
to devices that connect to a network such as the Internet. When your
computer or networking device (router, hub, interface, etc.) is connected to
a LAN or the Internet, a table (see ARP) relates the device’s IP address to its
corresponding physical (MAC) address on the LAN.
Ping is a utility/diagnostic tool that tests network connections. It is used to
determine if the host has an operating connection and is able to exchange
information with another host. The term (ping) is a reference to submarine
sonar, which sends out a signal and waits to hear it echo (“ping”) back from a
submerged object, much like how the ping utility functions in a network.
Port number is a preassigned address within a server that provides a direct route
from the application to the transport layer or from the transport layer to the
application of a TCP/IP system.
Section 508 is a portion of the United States Rehabilitation Act (29 U.S.C. 794d)
that requires Federal agencies to meet specific accessibility standards when
buying, developing, maintaining, or using information and multimedia
technology. This law was enacted to eliminate barriers in access for people
with disabilities and to encourage development of technologies that will help
achieve these goals. Visit www.extron.com to see how the MLCs comply
with Section 508.
SSI (server side include) is a type of HTML instruction set that tells the MLC
(or some other Web server) dynamically which material to include in the
contents of a Web page or e-mail. SSI files typically have a file extension of
.shtml .
Static IP refers to an IP address that has been specifically (instead of dynamically—
see DHCP above) assigned to a device or system in a network configuration.
This type of address requires manual configuration of the actual network
device or system and can only be changed manually or by enabling DHCP.
Subnet — See subnetwork.
Subnet address is the portion of an IP address that is specifically identified by the
subnet mask as the subnetwork.
Subnet mask is a 32-bit binary number (12 digit decimal number, xxx.xxx.xxx.
xxx) used on subnets (smaller, local networks) to help routers determine
which network traffic gets routed internally (within the subnetwork) to local
computers and which network traffic goes out to the rest of the network or
the Internet. It is an address mask used to identify the bits of an IP address
that are used for the subnet address. Using a mask, the router does not need
to examine all 32 bits, only those selected by the mask.
Subnetwork is a network that is part of a larger IP network and is identified by a
subnet address. Networks can be segmented into subnetworks to provide a
hierarchical, multilevel routing structure.
