A modem is a device which uses a telephone line to connect computers or computer systems. He sent his work to his publishers by modem. a piece of electronic equipment that allows information from one computer to be sent along telephone wires to another computer (modulator + demodulator). Electronic device that converts digital data into analog (modulated-wave) signals suitable for transmission over analog telecommunications circuits (e.g., traditional phone lines) and demodulates received analog signals to recover the digital data transmitted. The "modulator/demodulator" thus makes it possible for existing communications channels to support a variety of digital communications, including e-mail, Internet access, and fax transmissions. An ordinary modem, operating over traditional phone lines, has a data transmission speed limit of about 56 kilobits per second. ISDN lines allow communications at over twice that rate, and cable modems and DSL lines have transmission rates of over a million bits per second
A device that enables a user to dial into another computer via telephone lines to send and receive data The most common use of modems is for dialing into an Internet service provider to access the Internet or World Wide Web, though they can also be used to send faxes and transmit data directly from one computer to another Modems do not provide high bandwidth, and as a result, they do not provide high speed Internet access Most Americans who access the Internet from home use modems Back to top

A cable modem is a modem that uses part of the capacity of the local cable system to transmit data rather than TV channels to the home It works much like a Local Area Network Unlike the typical cable system, where TV signals can only be broadcast to the home, information is allowed to be transmitted in both directions
Provides high speed access to the internet at receive rates from 1,544k or faster The upload rate is much slower usually 256 or 512k Each cable company uses different standards for their cable modem
A modem designed to operate over cable TV lines Because the coaxial cable used by cable TV provides much greater bandwidth than telephone lines, a cable modem can be used to achieve extremely fast access to the World Wide Web This, combined with the fact that millions of homes are already wired for cable TV, has made the cable modem something of a holy grail for Internet and cable TV companies There are a number of technical difficulties, however One is that the cable TV infrastructure is designed to broadcast TV signals in just one direction - from the cable TV company to people's homes The Internet, however, is a two-way system where data also needs to flow from the client to the server In addition, it is still unknown whether the cable TV networks can handle the traffic that would ensue if millions of users began using the system for Internet access Despite these problems, cable modems that offer speeds up to 2 Mbps are already available in many areas
One form of high speed internet access and one type of DSL Essentially you get a high speed link to your server via a fibre optic cable (this usually is provided by a cable company which will either provide cable TV and/or phone services down the same line) Unlike ADSL you share this connection with others on the same cable link so speeds may fall as more use it to access the internet
A data modem that uses the bandwidth of a given cable system Because cable modems provide Internet access over cable, they are much faster than modems that use typical phone lines
An external modem that hooks up to the computer through a cable network A cable modem Internet connection is faster than one via DSL, and much faster than an ordinary phone line connection
For those cable customers lucky enough to be served by a cable company that offers them, Cable Modems offer a very high speed connection to the Internet, up to 10Megabits per second (several hundred times the speed of a modem) Technically speaking, though, a cable modem is not a modem at all, but a broadband network bridge
Modem designed for use on cable TV coaxial cable to provide a theoretical bandwidth of up to 10 Mbps, although actual speeds are usually much lower Cable modems share bandwidth with other units in the area, and are always on
A cable modem allows you to connect to a TV cable line for Internet access You do not need cable TV in your home first and you can run both the TV and the Internet on your computer simultaneously You can receive Interent information at speeds up to 1 5 Mega bits per second (Mbps or 1,500,000 bits per second) versus a 33 6 Kb (33,600 bits per second) of your standard modem to copper telephone wire connection
A modem supplied by a cable television operator that allows users to access the Internet or other information services over cable television networks, which comprise broadband coaxial cables and are capable of much greater speed than conventional twisted pair copper telephone lines
A special type of modem that connects to a local cable TV line to provide a continuous connection to the Internet Like an analog modem, a cable modem is used to send and receive data, but the difference is that transfer speeds are much faster A 56 Kbps modem can receive data at about 53 Kbps, while a cable modem can achieve about 1 5 Mbps (about 30 times faster) Cable modems attach to a 10Base-T Ethernet card inside your computer
A cable modem is a conversion device for connecting a computer to a cable TV service that provides Internet access Most cable modems have an Ethernet out-cable that attaches to the user's Wi-Fi gateway (See Wireless Gateway )
a device that allows a computer to connect to a cable television system and connect to a computer network - cable modems work at speeds approaching Ethernet connections - probable wide-spread future way to connect to the Internet
A cable modem is an Internet connection provided by a cable TV operator, typically with at least 1 5 Mbits per second of download bandwidth (50-100 times faster than modems that work over analog telephone lines)
A cable modem is a device that enables you to hook up your PC to a local cable TV line and receive data at about 1 5 Mbps This data rate far exceeds that of the prevalent 28 8 and 56 Kbps telephone modems and the up to 128 Kbps of ISDN and is about the data rate available to subscribers of Digital Subscriber Line (DSL) telephone service A cable modem is really more like a network interface card (NIC) than a computer modem The actual bandwidth for Internet service over a cable TV line is up to 27 Mbps on the download path to the subscriber with about 2 5 Mbps of bandwidth for interactive responses in the other direction However, since the local provider may not be connected to the Internet on a line faster than a T-1 at 1 5 Mpbs, a more likely data rate will be close to 1 5 Mpbs
is a modem that connects your PC to the Internet The cable modem is works with the same type of cable that brings cable TV service into your home This type of cable, coaxial cable, has a greater bandwidth than regular telephone lines and can provide extremely fast access to the Internet
A device that uses a cable TV signal to connect a computer to the Internet Cable modems offer download speeds of up to 56Mbps and upload speeds of up to 10Mbps
A device that enables you to hook up your PC to a local cable TV line and receive data at much faster rates than telephone modems and ISDN lines A strong competitor to DSL telephone service
a modem (=piece of equipment that allows information from one computer to be sent to another) that uses cable connections instead of telephone wires, and allows you to search the Internet very quickly. Modem used to convert analog data signals to digital form and vise versa, for transmission or receipt over cable television lines, especially for connecting to the Internet. A cable modem modulates and demodulates signals like a telephone modem, but is a much more complex device. Data can be transferred over cable lines much more quickly than over traditional phone lines. Transmission rates are typically around 1.5 megabits per second. Faster transmission is actually possible, but speed is usually restricted by the cable company's (typically slower) connection to the Internet. Cable Internet access is regarded as a replacement for slower dial-up and ISDN services, and is competitive with other broadband modes of delivery (e.g., DSL connections). See also broadband technology
A modem used to connect a computer to a cable TV service that provides Internet access Cable modems can dramatically increase the bandwidth between the user's computer and the Internet service provider Cable modems link to the computer via Ethernet, which means the service is online all the time However, Ethernet is a shared medium, and the speed will vary depending on how many customers on that cable segment are using the Web at the same time
A solution similar to ADSL A cable modem relies on the cable television backbone to provide fast access that is shared between small groups of local users
A short RS-232-C cable that connects two PCs so that they can communicate without the use of modems The cable connects the two computers' serial ports, and certain lines in the cable are crossed over so that the wires used for sending data by the other computer, and vice versa
A cable used to enable two computers to communicate with each other by emulating a modem The null modem cable is wired up so that the end connection from one to the other are: 2 connected to 3; 4 and 5 connected to 8; 6 connected to 20
A connection between two computers locally, causing the computers to act as if connected via a modem Generally used to transfer data from one machine to another
Cable adapter for V 24 links, used to link two data transmission installations, or two data installations The Null modem exchanges several lines, and thus creates a data installation from a data transmission installation, or vice versa
A cable in which the transmit and receive leads are crossed A null modem allows two devices to communicate over short distances (typically 50 ft or less) without using a modem
Sometimes you have two computers (DTEs) that you wish to connect directly to each other You have three choices 1 Think back to your high school gym class where they taught ballroom dancing If the number of boys did not exactly match the number of girls, some boys were given sashes, and told to dance backwards Similarly, you can get one of your computers to masquerade as a DCE 2 Buy a pair of modems and attach them back to back 3 Make a cable with wires crossed in a particular way so that it simulates two modems back to back This is called a null modem cable
A short serial cable that connects two personal computers so that they can communicate without the use of modems The cable connects the two computers' serial ports, and certain lines in the cable are crossed over so that the wires used for sending by one computer are used for receiving data by the other computer (Ref: Dyson, Dictionary of Networking)
