Mb/s (megabits per second): The measure for the rate at which a network functions.
For example, 1 Mb/s equals 1,000,000 bits per second (or 125,000 bytes per
second).
mDNS: As an alternative to a Domain Name Server, a device issues a Multicast
Domain Name Server (mDNS) notification to provide information regarding its
service. The notification includes the type of service (such as printing), the name of
the service (such as “your printer”), IP and port addresses, and other necessary
information. Each device on the network receives the notification and stores the
information in a personal DNS server.
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.
r
RJ-45: The type of plug at the end of an Ethernet cable.
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
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 address 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.
u
Unicast packet: A packet sent from one device on a network to another device on
the network.
