hub
A device that has multiple ports and that serves as a connection
point for Ethernet cables on a network. When data arrives at the hub
from one computer, it is copied to the other ports to be transmitted
to other computers. Unlike the more “intelligent” switch and router,
the hub does not direct or control data flow.

infrastructure A wireless network in which devices connect to each other through
network
an access point, or use a more sophisticated intermediary such as a
base station (gateway or router). Contrast with “ad hoc network.”

IP
Acronym for “Internet Protocol.” The set of rules that describe how to
send data between computers over the Internet. More specifically,
this protocol governs the routing of data messages, which are
transmitted in smaller components called packets.

IP address
Acronym for “Internet Protocol” address. An IP address is an
assigned number used to identify a computer that is connected to a
network or the Internet through the Transmission Control
Protocol/Internet Protocol (TCP/IP). An IP address consists of four
numbers (each of which can be no greater than 255) separated by
periods, such as 192.168.1.1.

Kbps
Abbreviation of “kilobits per second.” A measure of data transfer
speed through a modem or on a network.

LAN
Acronym for “local area network.” A group of computers and other
devices dispersed over a relatively limited area (for example, a
building) and connected by a communications link that enables any
device to interact with any other on the network.

MAC address
Acronym for “media access control” address. Each network adapter
and other network hardware device is manufactured with its own
unique MAC address. Networking standards and technologies use
MAC addresses to pass information between network devices.

Abbreviation of “megabits per second.” A measure of data transfer
speed. Do not confuse with megabytes per second, or MBps.

NAT
Acronym for “network address translation.” NAT is a base station
feature and software feature that allows all of the computers on a
network to access the Internet through one Internet Protocol (IP)
address, and helps ensure the computers’ security by hiding their
individual IP addresses.

network
A group of computers and associated devices that are connected by
communications paths. Networks can interconnect with other
networks and contain sub-networks. A network can be permanent or
temporary, small or large, and connect with cables and/or wirelessly.
