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 keys (Also known as encryption keys.) 64-bit and 128-bit encryption
keys used in WEP wireless security schemes. The keys encrypt
data over the WLAN, and only wireless PCs configured with WEP
keys that correspond to the keys configured on the device can
send/receive encrypted data.
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).
pass phrase A secret password used in WPA wireless data encryption.
Encryption is based on a WPA master key that is derived from the
pass phrase and the network name (SSID) of the device. The pass
phrase should be at least 20 characters long in order to deter a
hacker attempting to crack the pass phrase by recording a series of
frames then trying commonly used passwords offline until one
works (known as offline PSK dictionary attacks).
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.
PPP Point-to-Point Protocol
A protocol for serial data transmission that is used to carry IP
(and other protocol) data between your ISP and your computer.
The WAN interface on the Hata! Stil tanımlanmamış. uses two
forms of PPP called PPPoA and PPPoE. See PPPoA, PPPoE.
