HP 7200 - Manual (Page 151)

HEX Hexadecimal. The base 16 numbering system, which uses the
digits 0-9 plus the letters A-F.
hub No longer used much in modern home networks, a hub takes its
signal from each computer and sends it to all of the other
computers connected to the hub. Hubs, are passive; other
devices on the network plug into the hub in order to
communicate with one another. A hub does not manage the
network.
IP address A number that uniquely identifies the device on the network. IP
addresses are assigned dynamically through DHCP or AutoIP.
You can also set up a static IP address, though this is not
recommended.
infrastructure An infrastructure network uses a router, switch, or access point
to connect network elements.
MAC address Media Access Control (MAC) address that uniquely identifies
the HP All-in-One. This is a unique 12-digit identification number
assigned to networking hardware for identification. No two
pieces of hardware have the same MAC address.
NIC Network Interface Card. A card on your computer that provides
an Ethernet connection so that you can connect your computer
to a network.
RJ-45 connector The connector on the ends of an Ethernet cable. Although
standard Ethernet cable connectors (RJ-45 connectors) look
similar to standard telephone cable connectors, they are not
interchangeable. An RJ-45 connector is wider and thicker and
always has 8 contacts on the end. A phone connector has
between 2 and 6 contacts.
SSID Service Set Identifier. A unique identifier (up to 32 characters)
that differentiates one wireless local area network (WLAN) from
another. The SSID is also referred to as the network name. This
is the name of the network to which the HP All-in-One is
connected.
router A router provides a bridge between two or more networks. A
router can link a network to the Internet, link two networks and
connect both to the Internet, and help secure networks through
the use of firewalls and assigning dynamic addresses. A router
can also act as a gateway, while a switch cannot.
switch A switch makes it possible for several users to send information
over a network at the same time without slowing each other
down. Switches allow different nodes (a network connection
point, typically a computer) of a network to communicate directly
with one another.
