Modem and network

Neologisms are words, terms, or phrases that have been coined to reshape older terms in newer language form. One of the neologisms is a portmanteau that fuses two or more grammatical functions, for example, 'animatronics' blends 'animation' and 'electronics'. The term modem is also a portmanteau blending 'modulate' and 'demodulate'. A modem is an electronic device that encodes digital information by modulating an analog carrier signal and subsequently demodulating the signal in order to reproduce the original digital data. With respect to a computer, the modem modulates digital '1s and 0s' into sounds that can be transmitted via POTS (Plain Old Telephone Systems) and subsequently the sounds are demodulated into digital '1s and 0s' at the receiving computer at the other end. The amount of data that can be transferred measures the capacity of the modem in bits per second (bps). Nowadays, cable modems (transmits via cable television network), ADSL modems (Asymmetric Digital Subscriber Line, connects one or more computers to a phone line), radio modems (transmits via microwave radio links), optical modems (transmit via optic fibers over land and frequently used as submarine communications cable, which is laid beneath the sea to carry telecommunications between countries), satellite modems (transmits via satellites), powerline modems (transmits via the electric powerlines) and voice modems (regular modems but can play audio over telephone line, thereby enabling the transmission of speech via the Internet). Modems are used in used in cheap computer notebook, cheap laptop, laptop, laptop notebook, notebook, notebook computer, best computer notebook, best notebook, cheap notebook, gaming notebook, laptop notebook computer, refurbished notebook, refurbished notebook computer, tablet notebook, used notebook, used notebook computer, web cam notebook, wireless notebook.

Laptop / Notebook modems

Modems are attached in the laptop via the PCMCIA card slot. They are plug and play varieties and need software, provided with the modem, to operate effectively.
Laptop modems are available in 56K/ 33.6K / 28.8K varieties. Their features are compliant with V.90 and earlier ITU modem standards and are available as 16-bit PCMCIA Card, in Type II or Type III PCMCIA slot.

Combo modems

There are PCMCIA combo modem-ethernet adapter available, which can function both as a LAN and as a modem. The 32-bit Ethernet 10/100+ 56K Modem combines the highest performance 10/100Mbps Ethernet, 56K modem, GSM, AMPS cellular, and ISDN connectivity, in a single cable-free Integrated PC Card solution. Their Internet features make it easy to connect to information from any location, anywhere in the world.
