networks (100BASE-TX) and can transmit data up to speeds of 100 Mbps.
Category 5 cabling is better to use for network cabling than Category 3, because
it supports both Ethernet (10 Mbps) and Fast Ethernet (100 Mbps) speeds.
Channel Similar to any radio device, the OfficeConnect Wireless Cable/DSL gateway allows
you to choose different radio channels in the wireless spectrum. A channel is a
particular frequency within the 2.4GHz spectrum within which the Gateway
operates.
Client The term used to described the desktop PC that is connected to your network.
DHCP Dynamic Host Configuration Protocol. This protocol automatically assigns an IP
address for every computer on your network. Windows 95, Windows 98 and
Windows NT 4.0 contain software that assigns IP addresses to workstations on a
network. These assignments are made by the DHCP server software that runs on
Windows NT Server, and Windows 95 and Windows 98 will call the server to
obtain the address. Windows 98 will allocate itself an address if no DHCP server
can be found.
DNS Server Address DNS stands for Domain Name System, which allows Internet host computers to
have a domain name (such as 3com.com) and one or more IP addresses (such as
192.34.45.8). A DNS server keeps a database of host computers and their
respective domain names and IP addresses, so that when a domain name is
requested (as in typing "3com.com" into your Internet browser), the user is sent
to the proper IP address. The DNS server address used by the computers on your
home network is the location of the DNS server your ISP has assigned.
DSL modem DSL stands for digital subscriber line. A DSL modem uses your existing phone lines
to send and receive data at high speeds.
Encryption A method for providing a level of security to wireless data transmissions. The
OfficeConnect Wireless Cable/DSL Gateway uses two levels of encryption; 40/64
bit and 128 bit. 128 bit is a more powerful level of encryption than 40/64 bit.
ESSID Extended Service Set Identifier. The ESSID is a unique identifier for your wireless
network. You must have the same ESSID entered into the gateway and each of it's
wireless clients.
Ethernet A LAN specification developed jointly by Xerox, Intel and Digital Equipment
Corporation. Ethernet networks use CSMA/CD to transmit packets at a rate of 10
Mbps over a variety of cables.
Ethernet Address See MAC address.
Fast Ethernet An Ethernet system that is designed to operate at 100 Mbps.
Firewall Electronic protection that prevents anyone outside of your network from seeing
your files or damaging your computers.
