A tool (software) for finding files stored on anonymous FTP sites. You need to know the exact file name or a substring of it.

(Advanced Research Projects Agency Network) -- The precursor to the Internet. Landmark

Packet-switching network established in 1969 by the US Department of Defense as an experiment in wide-area-networking that would survive a nuclear war.

ASP - Active Server Pages (ASP). ASP files, which provide Web developers with an easier, faster, and more powerful way to build Web applications, are regular HTML pages with embedded scripts. These scripts can be written in any language and processed by the server when the file's URL is requested.

ATM -- Asynchronous Transfer Mode. International standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media such as E3, SONET, and T3.

(American Standard Code for Information Interchange) -- This is the de facto world-wide standard for the code numbers used by computers to represent all the upper and lower-case Latin letters, numbers, punctuation, etc. There are 128 standard ASCII codes each of which can be represented by a 7 digit binary number: 0000000 through 1111111, plus parity.

A high-speed line or series of connections that forms a major pathway within a network. The term is relative, as a backbone in a small network will likely be much smaller than many non-backbone lines in a large network.

The difference between the highest and lowest frequencies available for network signals. The term is also used to describe the rated throughput capacity of a given network medium or protocol. In short, bandwidth is a loose term used to describe the throughput capacity (measured in Kilobits or Megabits per second) of a specific circuit.

Unit of signaling speed equal to the number of discrete signal elements transmitted per second. Baud is synonymous with bits per second (bps). In common usage the baud rate of a modem is how many bits it can send or receive per second. Technically, baud is the number of times per second that the carrier signal shifts value - for example a 1200 bit-per-second modem actually runs at 300 baud, but it moves 4 bits per baud (4 x 300 = 1200 bits per second).

A computerized meeting and announcement system that allows people to carry on discussions, upload and download files, and make announcements without the people being connected to the computer at the same time. There are many thousands (millions?) of BBS's around the world, most are very small, running on a single IBM clone PC with 1 or 2 phone lines. Some are very large and the line between a BBS and a system like CompuServe gets crossed at some point, but it is not clearly drawn.
