Issues the credit to a credit card holder. When sale authorization is requested, the merchant's bank, requests the funds to be transferred from the credit card company, which in turn receives the funds from the issuing bank.

(In My Humble Opinion) -- A shorthand appended to a comment written in an online forum, IMHO indicates that the writer is aware that they are expressing a debatable view, probably on a subject already under discussion. One of may such shorthands in common use online, especially in discussion forums.

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 connects independent networks into a vast global Internet. Any time you connect 2 or more networks together, you have an internet - as in inter-national or inter-state.

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. As the Internet has become more popular many of the tools used on the Internet are being used in private networks, for example, many companies have web servers that are available only to employees. Note that an Intranet may not actually be an internet -- it may simply be a network.

(Internet Protocol Number) -- Sometimes called a dotted quad. A unique number consisting of 4 parts separated by dots, e.g. 165.113.245.2
Every machine that is on the Internet has a unique IP number - if a machine does not have an IP number, it is not really on the Internet. Most machines also have one or more Domain Names that are easier for people to remember.

(Internet Relay Chat) -- Basically a huge multi-user live chat facility. There are a number of major IRC servers around the world which are linked to each other. Anyone can create a channel and anything that anyone types in a given channel is seen by all others in the channel. Private channels can (and are) created for multi-person conference calls.

(Integrated Services Digital Network) -- Basically a way to move more data over existing regular phone lines. ISDN is rapidly becoming available to much of the USA and in most markets it is priced very comparably to standard analog phone circuits. It can provide speeds of roughly 128,000 bits-per-second over regular phone lines. In practice, most people will be limited to 56,000 or 64,000 bits-per-second.

(Internet Service Provider) -- An institution that provides access to the Internet in some form, usually for money.

The numeric address of a computer connected to the Internet; also called Internet address.

The Internet standard protocol that provides a common layer over dissimilar networks, used to move packets among host computers and through gateways if necessary.

The technical standards and design philosophy according to which digital networks will be designed. ISDN provides high-speed, high-bandwidth channels to every subscriber on the network, achieving end-to-end digital functions with standard equipment interface devices. The networks will enable a variety of mixed digital transmission services to be accommodated at a single interface (including voice and circuit and packet switched data).
