p
Packet: A message sent from one device on a network to other devices on the network.
Protocol: A language that devices on a network use to communicate with each other. A popular
network protocol is TCP/IP.
Proxy server: A proxy server acts as a security gate (such as a Web proxy) that restricts traffic
going through a network. The proxy intercepts requests to the network to see if it can fulfill the
requests itself. If not, it forwards the request to another server. Proxy servers have two main
purposes: improve performance and filter requests.
r
RJ-45: The type of plug at the end of an Ethernet cable.
Rendezvous: Apple’s configuration technology that automatically discovers and connects devices
over Ethernet and wireless networks. Rendezvous is integrated into the Mac OS X version 10.2
operating system.
Router: A complex networking device that directs packets from one network to another network. A
router can act as a gateway between a LAN and the Internet.
s
Server: A computer on a network that manages network resources. A network might have a
number of different server types. For example, a print server manages one or more printers, a file
server stores and manages files, and a network server manages network traffic.
SSID (Service Set Identifier): A unique identifier (up to 32 characters) attached to the header of
packets sent over a wireless LAN. An SSID provides basic access control to a wireless network. It
can also be used to logically segment a wireless subgroup of users and devices. An SSID
prevents access by any client device that does not have the SSID. By default, an access point
broadcasts its SSID in its beacon.
An SSID is also referred to as a Network Name because it is a name that identifies a wireless
network.
Static IP address: An IP address that is manually assigned to a device on a network. A static IP
address remains fixed until changed manually. Alternative methods for assigning IP addresses are
DHCP and AutoIP.
Subnet: A small network that acts as part of a large network. It is recommended that the printer
and the computers that use the printer all be on the same subnet.
Subnet mask: A number that identifies the IP addresses that belong to a subnet.
Switch: A network device that manages network traffic in order to minimize collisions and
maximize speed.
t
TCP/IP: Transmission Control Protocol/Internet Protocol (TCP/IP) is the network communication
protocol used on the Internet. The printer's built-in networking feature supports LANs that use
TCP/IP.
TKIP: See WPA. Temporal Key Integrity Protocol (TKIP).
u
Unicast packet: A packet sent from one device on a network to another device on the network.
