IP address
An IP address is the logical address of a network
adapter. The IP address uniquely identifi es computers
on a network. An IP address can be private, for use on a
LAN, or public, for use on the Internet or other WAN.
kbit/s
Kilobit per second
A unit used to express the speed of a network.
LAN
Local Area Network
A computer network covering a small local area, like
a home, offi ce, or small group of buildings such as a
home, offi ce, or college. Current LANs are most likely
to be based on switched Ethernet or Wi-Fi technology
running at 10, 100 or 1,000 Mbit/s (1,000 Mbit/s is also
known as 1 Gbit/s).
MAC address
It is a hardware address that uniquely identifi es each
node of a network.
Mbit/s
Megabit per second
A unit used to express the speed of a network.
NAPT
Network Address Port Translation
NAPT enables a local area network (LAN) to use one
set of IP addresses for internal traffi c and a second set
of addresses for external traffi c.
PPPoE
Point-to-Point Protocol over Ethernet
PPPoE is a network protocol for encapsulating PPP
frames in Ethernet frames. It is used mainly with
DSL services. It offers standard PPP features such as
authentication, encryption, and compression.
Protocol
On the Internet, “protocol” usually refers to a set of
rules that defi ne an exact format for communication
between systems.
Server
A computer or program that responds to commands
from a client. For example, a fi le server may contain an
archive of data or program fi les. When a client submits
a request for a fi le, the server transfers a copy of the fi le
to the client.
SSID
A SSID (Service Set Identifi er) is the name of a
particular local wireless network to which a user wants
to connect. Broadbcasting SSID’s displays a list of
wirelss networks in range allowing the user to select a
preferred one.
Subnet mask
The technique used by the IP protocol to determine
which network segment packets are destined for. The
subnet mask is a binary pattern that is stored in the
client machine, server or router, and is matched with
the IP address.
TCP
Transmission Control Protocol
The reliable transport protocol within the TCP/
IP protocol suite. TCP ensures that all data arrive
accurately and 100% intact at the other end. TCP’s
unreliable counterpart is UDP, which is used for
streaming media, VoIP and videoconferencing.
TCP/IP
A suite of communications protocols used to connect
hosts on the Internet. TCP/IP uses several protocols,
the two main ones being TCP and IP.
TKIP
(Temporal Key Integrity Protocol) – Using TKIP,
automatically changes the keys at a preset time
interval, making it much more diffi cult for hackers to
fi nd and exploit them.
UDP
User Datagram Protocol
One of the TCP/IP suite of protocols for data transfer,
which allows an application program on one machine
to send a datagram to an application program on
another machine.
URL
Universal Resource Locator
The global address of documents and other resources
on the World Wide Web.
USB
Universal Serial Bus
USB is a serial protocol and physical link, which
transmits all data differentially on a single pair of
wires. Another pair provides power to downstream
peripherals.
