Modem is short for Modulator-demodulator. What happens when you use a 56k modem is you send data that has been play so the surround melodys understand it. When you bid data with a modem you atomic number 18 demodulating, and returning it into digital data. So fundamentally what you give is a form of stuffion. The first modem was invented in the 60s for businesses, the epoch line of the evolution of modems ar as follows three hundred bits per second - 1960s by means of 1983 or so 1200 bps - Gained usuality in 1984 and 1985 2400 bps 9600 bps - First appeared in late 1990 and early 1991 19.2 kilobits per second (Kbps) 28.8 Kbps 33.6 Kbps 56 Kbps - Became the standard in 1998 ADSL, with theoretical maximum of up to 8 megabits per second (Mbps) - Gained popularity in 1999 The reason for the evolution In modems is over out-of-pocket to the particular that people were starting to interchange more(prenominal) an more data. Such as programs and since programs constantly gr ew in size due to the quality of the graphical user interface (Graphical User Interface) and size of the files themselves modems had to grow in urge on because it would take an unreasonable amount of age to tape contain roundthing. In the beginning people created bulletin boards that shared views on certain topics and the speed of the modem was 300bits per second this was okay because that was 30 characters typed on the keyboard a second and no one was that fast, but when programs began to deepen thats when they noniced how slow the modem actually was. Modems withdraw and receive data in full-duplex which means that it sends and receives data at the same time modems that transfer only one way are called half-duplex. When modems evolved the creators of the modems had... Good attain on modems. Data communicates from wires and wireless. With an IP ADRESS you can track anybody. It exces sively stores the data(past history)in youre! cookies.. You have stated nice simple facts, real useful and interesting. Well done. However, just now wondering where you got all your facts from... wellhead they are accu prescribe but I think you should beak that ADSL or broadband to be more precise - became popular at a later time in legal injury of Europe, not sure when in the US tho. Also, ADSL as I assign is broadband - and in the same category you have cablegram and also satellite modems. All of which are very fast. The speed in terms of location differs a little. at that place are T1 (E1) T2, T3, Cable, DSL, ADSL, Satellite etc etc. Good paper with oodles of facts. I am a LAN guy myself. Cant full of life without those Gig-a-minute downloads. Modems do NOT compress data, they convert it. Modems although, Mux and Demux predicts. They take a higher bit rate signal and convert it to a lesser rate signal so it may computer programme over a huge distance. What virtually fiberoptics (info direct thru light bent through glass), you didnt mention it. You also didnt regular(a) mention how modems interface with routers, and switches. I would be curious to chance on your bibliography, as some of the more tech info you wrote about seems to be out of your field, and there is no citations, so I am worried of some the info not organism properly cited. You should have researched more. And this is just from my knowledge, but i am certified in this field. A modem, is an electrical power converter. For simulation your 56k modem performs: First, It takes a digital (computer) signal. i.e (binary ((machine)) legislation 01000010010010) and converts it to an analog signal that your phone lines can handle and wickedness versa. static display: [computer]-digital-[modem]-analog-[phone line system]-analog-[modem]-digital-[computer] One Major position Error: Modems transfer and receive data in full-duplex -Correction- There A!
