The Modem :: essays research papers

The ModemFirst of all I would like to start with an excogitation I chose this topicbecause I thought it would be interesting to larn about how a modem works in afigurer. With modem we be subject to access the Internet BBS or Bulletin BoardSystems.The MODEM is one of the smartest electronic computer hardware tools ever created. modem isan abbreviation of Modulator De Modulator it is fairly simple to explainthrough and through the telephone lines we are able to send put acrosss among one acecomputer or a group of computers. The Originating computer sends a coded messageto the Host computer which decodes it and there we have the power to access theInternet, speech to other throng through terminal programs and retrieve files fromother computers. The premier patented computer modem was make by Hayes in the premature eighties and from there they rapidly developed the first modem speed was three hundred baud and from there a 600 baud than 1200 and so on. The fastest modem madeto day is a 56k which is very fast. Not as fast as ISDN (The Wave offered throughRogers cable) or even as advanced as Satellite modem. Most people now have 14.4or 28.8 baud modems (Baud is "Slang" for Baud Rate Per Second) the reason forthe increase in 14.4 and 28.8s is that they are cheap and fairly recent andhavent gone out of date yet. there are two types of modem external andexternal modems internal plugs into a 16 bit port inside your computer andexternal connects through either a serial (mouse)port or a parallel(printer)port most people like the external modems because they dont take up anextra space in your computer (according to PC Computing) prices in modems rangeprice from $100 (28.8bps) to $500(software upgradable 56k). telefax machinesalso have a form of modem in them, usually a 2400baud modem to decode themessage. So imagine a world without the modem for a cooperate NO fax NO InternetNO direct computer communications whatsoever.The three major modem manufacture s are Hayes (original modem) US Robotics andMicrosoft.In conclusion life today it would be very hard to bear without modems somebusinesses would cease to exist due to ill communications between offices andwithout modems we wouldnt have videoconfrencing e-mail and other tools we have
