The Modem
First of all I would like to start with an introduction I chose this topic because I thought it would be interesting to learn about how a modem works in a computer. With modem we are able to access the Internet BBS' or Bulletin Board
Systems.
The MODEM is one of the smartest computer hardware tools ever created. modem is an abbreviation of Modulator De Modulator it is fairly simple to explain; through the telephone lines we are able to send messages between one single computer or a group of computers. The Originating computer sends a coded message to the Host computer which decodes it and there we have the power to access the
Internet, talk to other people through terminal programs and retrieve files from other computers. The first patented computer modem was made by Hayes in the early eighties and from there they rapidly developed the first modem speed was
300 baud and from there a 600 baud than 1200 and so on. The fastest modem made today is a 56k which is very fast. Not as fast as ISDN (The Wave offered through
Rogers cable) or even as advanced as Satellite modem. Most people now have 14.4 or 28.8 baud modems (Baud is "Slang" for Baud Rate Per Second) the reason for the increase in 14.4 and 28.8's is that they are cheap and fairly recent and haven't gone out of date yet. There are two types of modem external and external modems internal plugs into a 16 bit port inside your computer and external connects through either a serial (mouse)port or a parallel
(printer)port most people like the external modems because they don't take up an extra space in your computer (according to PC Computing) prices in modems range price from $100 (28.8bps) to $500(software upgradable 56k). Facsimile machines also have a form of modem in them, usually a 2400baud modem to decode the message. So imagine a world without the modem for a second; NO fax NO Internet
NO direct computer communications whatsoever.
The three major modem manufactures are Hayes (original modem) US Robotics and
Microsoft.
In conclusion life today it would be very hard to live without modems some businesses would cease to exist due to ill communications between offices and without modems we wouldn't have videoconfrencing e-mail and other tools we have
In order to complete this assignments I need to gather as much information as I can from different sources, such as course notes, internet and a Newspaper.
The following Essay must be a minimum of 5 paragraphs of 10-12 sentences each (a sentence is 10 words or more) .
In response to the question set, I will go into detail of the study, consisting of the background, main hypotheses, as well the aims, procedure and results gathered from the study; explaining the four research methods chosen to investigate, furthering into the three methods actually tested.
[Note: Please note that this assignment was written in March/April 2014, and so the content was current or recent at the time.]
Give a complete evaluation of the research issues in relation to the topic and any questions that you have not yet answered.
write about for the topic. It is all right to change the subject many times if I absolutely have to.
This assignment is my own work, presented in my own words, ALL sources of information have been cited and any direct quotations are contained within quotation marks.
A high speed Internet connection is required to stream video. The Netflix Help Center recommends an Internet connection speed of 5.0 Megabits per second (Mbps) for HD video ("Internet Connection Speed Recommendations") Today most American households have access to broadband speeds capable of high-definition video. According to Anne Neville of the National Telecommunications and Information Administration, 98% of Americans have access to broadband speeds of six megabits per second and 83% to speeds of twenty five Mbps or more (Neville). These speeds are more than adequate for HD quality video streaming. With the current broadband initiatives in place this should continue to improve in coming years, along with the possibility of even greater speeds. Beginning in November 2013, Cox Communications began offering increased Internet connectio...
It all sounds like a lot to cover in a short essay so I will introduce a company

Digital Subscriber Line new technology that takes advantage of standard copper telephone line to provide secure, reliable, high-speed Internet access. DSL refers to the family of digital subscriber line technologies, such as ADSL, HDSL, and RADSL. Connection speed for DSL ranges from 1.44 Mbps to 512 Kbps downstream and around 128 Kbps upstream. Unlike traditional connections DSL such as analog modems and IDSN, DSL deliver continuous “always on” access. That means multimedia-rich websites, e-mail, and other online applications are available anytime. DSL makes it possible for you to remain online even while you’re talking on the telephone-without jeopardizing the quality of either connection. DSL is available in a spectrum of speeds. Some are best home use, while others are designed to accommodate rigorous business demands. Whether for business or the home, DSL, offers unsurpassed price/performance value compared to other online options. There are the five facts that one should know about DSL. It is remarkably fast. With DSL service, you can benefit from Internet speeds that are up to 12 minutes faster than a typical ISDN connection and 50 times faster than traditional 28.8 Kbps modems. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same with a traditional 28.8 Kbps. It’s highly reliable. One can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. It’s inherently secure. DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-upp modems or cable modems. DSL protects your valuable data with the most secure connection available. It’s surprising affordable. DSL is widely recognized as the most cost-effective connectivity solution for small buisness. DSL delivers industrial- strength like speed to multiple users at only 25% of typical TI costs. There is no better price option available. DSL is also an exceptional value for home users. At about $2 a day for services that meets the needs of most people. The connection is always on. It’s ready to run every minute of the day. There’s no more logging on and off. No more busy signals or disconnects. This gives you the freedom to focus on what you want to accomplish on line rather than focusing on trying to get connected.

This report will describe the two forms of data communications in terms of the physical interfaces and modes of operation. It will describe the features of data communications equipment in relation to synchronous and asynchronous communication including modems, network terminating units and sending and receiving equipment.
Since its inception, the telephone has become one of the most important inventions of all time. Although some were skeptical about its replacement over telegrams, in the end the advent of this fine communication equipment has won the hearts of many. As a matter of fact, the telephone system had come to numerous facelifts that it literally connected the world before the internet was born. Because of its importance, homes and businesses can not live without it. In the U.S. alone, most if not all have a phone in the house.
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
