Mask
See network mask .
Mbps
Abbreviation for Megabits per second, or one million bits per second. Network data rates are
often expressed in Mbps.
NAT
Network Address Translation
A service performed by many routers that translates your network’s publicly known IP address
into a
private IP address for each computer on your LAN. Only your router and your LAN know
these addresses; the outside world sees only the public IP address when talking to a computer
on your LAN.
Network
A group of computers that are connected together, allowing them to communicate with each
other and share resources, such as software, files, etc. A network can be small, such as a
LAN ,
or very large, such as the Internet .
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
binary, IP address, subnet .
NIC
Network Interface Card
An adapter card that plugs into your computer and provides the physical interface to your
network cabling. For Ethernet NICs this 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.
