The Modem :: essays research papers

The ModemFirst of all I would like to start with an introduction I chose this topicbecause I thought it would be interesting to learn rough how a modem works in acomputer. With modem we atomic number 18 able to access the Internet BBS or Bulletin BoardSystems.The MODEM is one of the smartest computer hardware tools incessantly created. modem isan abbreviation of Modulator De Modulator it is fairly simple to explainthrough the telephone lines we are able to send messages between one singlecomputer 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, talk to other people through destination programs and retrieve files fromother computers. The starting line patented computer modem was made by convert in theearly eighties and from there they rapidly developed the first modem speed was300 baud and from there a 600 baud than 1200 and so on. The spendthriftest modem madetoday i s 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Rate Per Second) the reason forthe increase in 14.4 and 28.8s is that they are cheap and fairly recent andhavent gone out of date yet.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 successive (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). Facsimile machinesalso have a form of modem in them, usually a 2400baud modem to decode themessage. So imagine a world without the modem for a second NO fax NO InternetNO direct computer communications whatsoever.The three major modem manufactures are Hayes (original modem) US Robotics andMicrosoft.In conclusion life today it would be very hard to live 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
