HP 7210v manual Hex

Set up your network

Chapter 13

(continued)
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.
