internet.
Internet
(Upper case I) The vast collection of inter-connected networks that all use the
TCP/IP protocols and that evolved from the ARPANET of the late 60's and early
70's. The Internet now (July 1995) connects roughly 60,000 independent
networks into a vast global internet.
Interrupt
In a computer, some tasks must be performed regularly and without delay. This
is possible because the CPUs provide special interrupt vectors. These vectors
each point to some short program sequence. An interrupt stops the currently
running program and the segment to which the vector points is executed.
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.
IP
Internet Protocol. The IP (currently IP version 4, or IPv4), is the underlying
protocol for routing packets on the Internet and other TCP/IP-based networks.
IRC
Internet Relay Chat. IRC was developed in the late 1980s as a way for multiple
users on a system to "chat" over the network. Today IRC is a very popular way
to "talk" in real time with other people on the Internet. However, IRC is also one
avenue hackers use to get information from you about your system and your
company. Moreover, IRC sessions are prone to numerous attacks that while not
dangerous can cause your system to crash.
ISP
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.
ITU-TSS
International Telecommunications Union - Telecommunication Standards
Sector. New name for the standard making organization CCITT. See CCITT.
Jack Type
Different types of jacks (RJ11, RJ45, or RJ48) can be used for an ISDN line.
The RJ11 is the most common in the world and is most often used for analog
phones, modems, and fax machines. RJ45 and RJ48 are essentially the same,
as they both have the same 8-pin configuration. An RJ11 jack can fit into an
RJ45/RJ48 connector, however, an RJ45/RJ48 cannot fit into an RJ11
connector.
LAN
Local Area Network is a shared communication system to which many
computers are attached. A LAN, as its name implies, is limited to a local area.
This has to do more with the electrical characteristics of the medium than the
fact that many early LANs were designed for departments, although the latter
