second. Network data rates are often expressed in Mbps.
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 mask
A network mask is a sequence of bits applied to an IP 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).
