COMPUTER
A computer consists of hardware and software. Hardware is the components such as the keyboard, screen/VDU (visual display unit), mouse and all the electronic circuitry inside the computer, disk, chips, etc. The software gives instructions to the computers to enable them to perform tasks, often using programmed languages. The type of information processed by computers is called data.

FAX-MACHINE
Fax-machine is short for facsimile machine. It is a device that can send or receive pictures and text over a telephone line.
The idea of fax-machines has been around since 1842, when Alexander Bain invented a machine capable of receiving signals from a telegraph wire and translating them into images on paper. In 1850, a London inventor named F. C. Blackwell received a patent for a similar machine, which he called a copying telegraph. But while the idea of fax machines has existed since the 1800s, fax-machines did not become popular until the mid 1980s.
A fax machine consists of an optical scanner for digitizing images on paper, a printer for printing incoming fax messages, and a telephone for making the connection. The optical scanner generally does not offer the same quality of resolution as stand-alone scanners. Some printers on fax machines are thermal, which means they require a special kind of paper. In discussing the fax-machine I would be talking about a particular model of interest to me, which is the NEST Routing.
NEST (Novell Embedded Systems Technology) Routing; This method of routing is similar to T.30 sub addressing in that the sender enter a fax extension number when dialing the number (i.e. 9268182#215)
Impact on private life
- You can send document and know instantly that it has being received.
- It is a way of keeping in touch with family.
- You can send your C.V.’s to businesses by fax.
Impact on public life
- It can be used to send contract to different places.
- It can be used for transmitting hand written notes.
- It can be used for sending resumes.
- It can be used for transmitting illustrations.
Advantages
- Does not require manual intervention
No special software/telephone line required
It’s 100% reliable (assuming the send enters the extension number).
- Does not require sender to replace fax machine with newer model (Novell intends to sell add-on devices for roughly $50 which will add NEST routing to existing fax machines).
- Does not require any special modem or hardware on receiving end
- Does not require support for anything beyond the basic T.30 protocol (the NEST routing information is carried in the TSI frame)
Disadvantages
- Requires that sender either have a new fax machine with support for NEST addressing or have a NEST addressing device added to their fax machine.
- Requires that sender knows how to use NEST addressing.
Widespread acceptance of Novell's scheme is in doubt since it has not been adopted by any official standards body (as has T.30 sub addressing).
- It requires a special phone line from Telephone Company that is more expensive that a standard (POTS) phone line.
- DID line cannot be used to outgoing faxes (requires an additional standard phone line, although a single modem can be shared between the DID and POTS line for both incoming and outgoing faxes).
- Requires special hardware and modem to intercept DID signalling information.
