other computers on the network. It is quite common to have one host
machine provide several services, such as WWW and USENET.
HTTP
Acronym for HyperText Transfer Protocol. The client/server protocol
used to access information on the World Wide Web.
IEEE 802
Standards
A set of standards developed by the IEEE to define methods of access
and control on LANs. The IEEE 802 standards correspond to the
physical and data-link layers of the ISO Open Systems Interconnection
model, but they divide the data-link layer into two sublayers. The logical
link control (LLC) sublayer applies to all IEEE 802 standards and covers
station-to-station connections, generation of message frames, and error
control. The MAC sublayer, dealing with network access and collision
detection, differs from one IEEE 802 standard to another: IEEE 802.3 is
used for bus networks that use CSMA/CD, both broadband and
baseband, and the baseband version is based on the Ethernet standard.
IEEE 802.4 is used for bus networks that use token passing, and IEEE
802.5 is used for ring networks that use token passing (token ring
networks). In addition, IEEE 802.6 is an emerging standard for
metropolitan area networks, which transmit data, voice, and video over
distances of more than five kilometers.
internet (Lower case I) Any time you connect two or more networks together,
you have an internet.
Internet (Upper case I) The worldwide collection of networks and gateways that
use the TCP/IP suite of protocols to communicate with one another. At
the heart of the Internet is a backbone of high-speed data communication
lines between major nodes or host computers, consisting of thousands of
commercial, government, educational, and other computer systems, that
route data and messages. One or more Internet nodes can go off line
without endangering the Internet as a whole or causing communications
on the Internet to stop, because no single computer or network controls it.
Currently, the Internet offers a range of services to users, such as FTP,
email, the World Wide Web, Usenet news, Gopher, IRC, telnet, and
others. Also called Net.
Intranet 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.
ISP (Internet
Service
Providers)
ISPs 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.
