A very common method of networking computers in a LAN.  There are a number of
adaptations to the IEEE 802.3 Ethernet standard, including adaptations with data rates
of 10 Mbits/sec and 100 Mbits/sec over coaxial cable, twisted-pair cable and fiber-optic
cable. The latest version of Ethernet, Gigabit Ethernet, has a data rate of 1 Gbit/sec.

Frequently Asked Questions.  FAQs are documents that list and answer the most
common questions on a particular subject.

The FCC (Federal Communications Commission) is in charge of allocating the
electromagnetic spectrum and thus the bandwidth of various communication systems.

A gateway is a computer system or other device that acts as a translator between two
systems that do not use the same communication protocols, data formatting structures,
languages, and/or architecture.

Any computer on a network that is a repository for services available to other
computers on the network. It is quite common to have one host machine provide
several services, such as WWW and USENET.

Internet Assigned Number Authority acts as the clearing house to assign and coordinate
the use of numerous Internet protocol parameters such as Internet addresses, domain
names, protocol numbers, and more.  Use a search engine to find the current IANA web
site.

Internet Control Message Protocol is a message control and error-reporting protocol
between a host server and a gateway to the Internet  ICMP uses Internet Protocol (IP)
datagrams, but the messages are processed by the TCP/IP software and are not directly
apparent to the application user.

(Upper case “I”).  The vast collection of inter-connected networks that use TCP/IP
protocols evolved from the ARPANET (Advanced Research Projects Agency Network)
of the late 1960’s and early 1970’s.

(Lower case “i”).  Any time you connect two or more networks together, you have an
internet.

A private network inside a company or organization that uses the same kinds of
software that you would find on the public Internet, but that is only for internal use.

Internet Protocol.  (Currently IP version 4 or IPv4).  The underlying protocol for
routing packets on the Internet and other TCP/IP-based networks.

IP Control Protocol allows changes to IP parameters such as the IP address.

Internet Service Providers provide connections into the Internet for home users and
businesses.  There are local, regional, national, and global ISPs.  You can think of local
ISPs as the gatekeepers into the Internet.

Local Area Network is a shared communication system to which many computers are
