FAQ:-
Abbreviation for frequently asked questions, pronounced Tack." A USENET document contains answers to questions that new users often ask when they first subscribe to a newsgroup. The FAQ contains answers to common questions that the seasoned users have grown tired of answering. New users should look for and read the FAQ before posting their question, just in case the FAQ contains the answer.
FAQ's are posted to the newsgroup on a regular basis, weekly or monthly, and some grow so large that they are divided into sections; the designation 1/4 indicates that the section being viewed is the first of a total of four sections.
Fast Ethernet:-
A term applied to the IEEE 802.3 Higher Speed Ethernet Study Group proposals, which ere originally developed by Grand Junction Networks, 3Com, SynOptics, Intel, and others. Also known as 100BaseT Fast Ethernet modifies the existing Ethernet standard to allow speeds of 10 or 100 megabits per second, or both, and uses CSMA/CD access method.
The official standard defines three physical-layer specifications for different cabling types:
• 100BaseTX for two-pair Category 5 unshielded twisted-pair.
• 100BaseT4 for four-pair Category 3, 4, or 5 unshielded twisted-pair.
• 100BaseFX for fiber-optic cable.
Fax:-
Abbreviation for facsimile. The electronic transmission of copies of documents for reproduction at a remote location. The term fax can be used as a verb for the process, and as a noun for the machine that does the work and also for the item that is actually transmitted. The sending fax machine scans a paper image and converts the image into a form suitable for transmission over a telephone line. The receiving fax machine decodes and prints a copy of the original image. Each fax machine includes a scanner, modem, and printer. Originally, facsimile machines were rotating drums (CCITT Groups 1 and 2), then came moderns (CCITT Group 3), and eventually they will be completely digital (CCITT Group 4).
Fax Modem: -
An adapter that fits into a PC expansion slot providing many of the capabilities of a full-sized fax machine, but at a fraction of the cost. Some external modems also have fax capabilities. The advantages of a fax modem include ease of use and convenience; the main disadvantage is that the material you want to fax must be in digital form in the computer. Unless you have access to a scanner, you cannot fax hand-written notes, line art, or certain kinds of graphics. Most faxes sent directly from a PC using a fax modem are text files. There ere three main classes of fax modem:
• SendFax : Originally developed by Sierra Semiconductor, these fax modems are send-only, and date from the days when a single-function fax modem was much cheaper than one that could both send and receive.
• Class 1 : an early fax-modem standard that specified that most of the processing of the fax document should be performed by the application software.
• Class 2 : a more recent standard that shifts the task of preparing the fax document to the fax modem itself. In this standard, the modem hardware manages all data-compression and error-correction functions. Most Class 2 modems use an interim version of the standard from August 1990, but the standard was revised further, with the final version gaining approval in November 1992. Fax modems that support the first version are described as Class 2 modems, while those that support the later standard are known as Class 2.0 modems. The Intel Satisfaction fax modems follow another standard, called CAS Communications.
