Monitor Also called "Roving Analysis", allow you to attach a network
analyzer to one port and use it to monitor the traffics of
other ports on the switch.
network A network mask is a sequence of bits applied to an IP
mask address to select the network ID while ignoring the host
ID. Bits set to 1 mean "select this bit" while bits set to 0
mean "ignore this bit." For example, if the network mask
255.255.255.0 is applied to the IP address 100.10.50.1,
the network ID is 100.10.50, and the host ID is 1. See
also binary, IP address, subnet, "IP Addresses Explained"
section.
NIC Network Interface Card
An adapter card that plugs into your computer and provides
the physical interface to your network cabling, which
for Ethernet NICs is typically an RJ-45 connector. See
Ethernet, RJ-45.
packet Data transmitted on a network consists of units called
packets. Each packet contains a payload (the data), plus
overhead information such as where it came from (source
address) and where it should go (destination address).
ping Packet Internet (or Inter-Network) Groper
A program used to verify whether the host associated with
an IP address is online. It can also be used to reveal the IP
address for a given domain name.
port A physical access point to a device such as a computer or
router, through which data flows into and out of the device.
protocol A set of rules governing the transmission of data. In
order for a data transmission to work, both ends of the
connection have to follow the rules of the protocol.
