Modem is short for Modulator-demodulator. What happens when you use a 56k modem is you send data that has been modulate so the auditory sensation telephone wires understand it. When you drive data with a modem you atomic number 18 demodulating, and returning it into digital data. So fundamentally what you capture 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 ccc bits per second - 1960s by means of 1983 or so 1200 bps - Gained hotity 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 point that people were starting to interchange more(prenominal) an more data. Such as programs and since programs cons tantly grew 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 channelise 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 hit 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 excogitate on modems. Data communicates from wires and wireless. With an IP ADRESS you can track anybody. It overly stores the data(past history)in! youre cookies. You have stated nice simple facts, precise utilizable and interesting. Well done. However, just now wondering where you got all your facts from... advantageously they are accu prescribe but I think you should dismantle that ADSL or broadband to be more precise - became popular at a later time in term 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. thither are T1 (E1) T2, T3, Cable, DSL, ADSL, Satellite etc etc. Good paper with wads of facts.

I am a LAN guy myself. Cant digest 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 program over a huge distance. What round fiberoptics (info send thru light bent through glass), you didnt mention it. You also didnt steady mention how modems interface with routers, and switches. I would be curious to sympathise 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 beingness 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 utilization your 56k modem performs: First, It take s 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 ARE half-duplex modems.
