Ethernet	The most popular LAN communication technology. There are a variety of types of
	Ethernet, including 10Mbps (traditional Ethernet), 100Mbps (Fast Ethernet), and
	1,000Mbps (Gigabit Ethernet). Most Ethernet networks use Category 5 cabling to carry
	information, in the form of electrical signals, between devices. Ethernet is an
	implementation of CSMA/CD that operates in a bus or star topology.

F

Fast Ethernet	Fast Ethernet, also called 100BASE-T, operates at 10 or 100Mbps per second over
	UTP, STP, or fiber-optic media.
Firewall	Firewall is considered the first line of defense in protecting private information. For
	better security, data can be encrypted. A system designed to prevent unauthorized
	access to or from a private network. Firewalls are frequently used to prevent
	unauthorized Internet users from accessing private networks connected to the Internet,
	especially Intranets all messages entering or leaving the intranet pass through the
	firewall, which examines each message and blocks those that do not meet the specified
	security criteria.

G

Gateway	A gateway links computers that use different data formats together.
Group	Groups consist of several user machines that have similar characteristics such as being
	in the same department.
H
HEX	Short for hexadecimal refers to the base-16 number system, which consists of 16
	unique symbols: the numbers 0 to 9 and the letters A to F. For example, the decimal
	number 15 is represented as F in the hexadecimal numbering system. The hexadecimal
	system is useful because it can represent every byte (8 bits) as two consecutive
	hexadecimal digits. It is easier for humans to read hexadecimal numbers than binary
	numbers.
I
Intranet	This is a private network, inside an organization or company that uses the same
	software you will find on the public Internet. The only difference is that an Intranet is
	used for internal usage only.
Internet	The Internet is a globally linked system of computers that are logically connected based
	on the Internet Protocol (IP). The Internet provides different ways to access private and
	public information worldwide.
Internet address	To participate in Internet communications and on Internet Protocol-based networks, a
	node must have an Internet address that identifies it to the other nodes. All Internet
	addresses are IP addresses
IP	Internet Protocol is the standard that describes the layout of the basic unit of
	information on the Internet (the packet) and also details the numerical addressing
	format used to route the information. Your Internet service provider controls the IP
	address of any device it connects to the Internet. The IP addresses in your network
	must conform to IP addressing rules. In smaller LANs, most people will allow the DHCP
	function of a router or gateway to assign the IP addresses on internal networks.
IP address	IP address is a 32-binary digit number that identifies each sender or receiver of
	information that is sent in packets across the Internet. For example 80.80.80.69 is an IP
	address. When you “call” that number, using any connection methods, you get
	connected to the computer that “owns” that IP address.
ISP	ISP (Internet Service Provider) is a company that maintains a network that is linked to
	the Internet by way of a dedicated communication line. An ISP offers the use of its
	dedicated communication lines to companies or individuals who can’t afford the high
	monthly cost for a direct connection.
J
JAVA	Java is a programming language that is specially designed for writing programs that can
	be safely downloaded to your computer through the Internet without the fear of viruses.
