Basically, modem is used to connect the analog world to the digital world. In other words, you can say it is the device that is used to convert the analog signal to digital signal. For eg. the modem connected with a computer is usually converts the analog signal that comes through the wire to the digital bit bcoz computer can only understands the digital signal...
A modem is connect to a phone line and to the computer. When the computer wishes to connect to the internet it takes the line of the hook and dials to an ISP. The ISP computer answers the call and then acts as a gateway for the client system. Requests are sent to the ISP computer which receives the necessary data and sends it back over the phone line to the client computer. When the internet is no longer required the client computer ends the call and hands up the phone line.
A modem is a modulator and demodulator device that modulates the analog carrier signal to encode the digital information and demodulates the signal to decode the transmitted information. The modem usually produces a signal that can be transmitted easily and decoded to reproduce the original data.
A modem stands for modulation demodulation. A modem basically converts analog signals to digital signals or vice versa. This convertion is required because the subscriber line through which you are getting your internet, carries analog signals. But, a computer understands only digital signals. So the convertion to digital signals is required. Also it has to be changed back to analog signals because analog signals can go longer distances through your subscriber line.

to convert analog to digitial data and digital to analog. it used in internet modem means modulation demodulation
For internate connection.a modem is use to analog data transmission to digital data transmission.
A modem is used to connect a computer to a telephone line, most commonly to connect to the Internet.
no, you can use a modem, an example is dial up internet access :P modems are also used for remote connections

You would want to reconfigure a modem if it is set up to work with one Internet Service Provider (ISP) but you want to switch to another. Most modems can be reconfigured easily by entering your new username and password into the settings. This information will be provided to you by your ISP when you sign up. Here is a link to a few common modems (Australian) and the steps needed for reconfiguration: http://www.comparebroadband.com.au/article_1575_How-to-configure-your-old-Telstra-or-Optus-modem-to-use-with-another-Internet-provider.htm
Routers, Switches, Modems, and Hubs, but mostly Routers
In the past external modems connected to the COM (or serial) port. However, most modern external hardware is USB these days, modems are no exception.
Broadband internet access use many different types of modems, but most modems tend to accomplish internet access, and therefore almost all modems work to your advantage.
There are three types of cellular modems - cell phones, aircards, and cellular routers. All three of these have the same purpose which is to connect a computer to the internet.
Conexant is a company that manufactures a number of technology items including dial-up modems. Dial-up modems can be used to connect a computer to the internet via phone line (albeit at very slow speeds compared to broadband modems). Dial-up modems also allow one to use their computer as a fax machine.
Cable modems are a kind of device that you hook up to your computer that is used to deliver broadband acess in the form of cable internet to your computer. It allows you to surf the web.
PC Card modems do exist.
DSL, Cable modems, wireless internet and satellite internet.
Wireless router modems are what you use to connect to the internet. They can be found at any electronic store. Or you can pay a small fee & rent one provided by your internet service provider.
Broadband internet satellite service is an connection to the internet. It is usually used in a dial-up access and modems. They are limited to a bitrate of less than 56 kbit/s and require the use of a telephone line.
No.
Advantage: Modems not expensive. Higher transmission speed. Telephone can still be used. :)
Soft modems and dial up modems are some of the more dated modems that were created. They are considered to be land line modems since they used wired connections and ports.
A modem is a Modulator Demodulator. It turns computer code into an audio signal, that can be sent over telephone wires and convert signals coming in, back to code again.A computer modem is a chip on a computer to which you can connect a phone line. Modems can be used to access dial up internet. Modems can also be used to allow you to use your computer's microphone and speakers as a telephone. Modems are rarely used today, as faster forms of digital communication exist.
