How is data transmitted over telephone lines?

Using a dial-up line to transmit data is similar to using the telephone to make a call. A modem at the sending end dials the telephone number of a modem at the receiving end. When the modem at the receiving end answers the call, a connection is established and data can be transmitted.

What is transmission network in telecommunication?

Telecommunication networks are transmission systems enabling information to be transmitted in analogue or digital form between various different sites by means of electromagnetic or optical signals. The networks are based either on wired or wireless infrastructures.

What is data transmission technology?

Data transmission refers to the process of transferring data between two or more digital devices. Data is transmitted from one device to another in analog or digital format.

Which technology is used in telephone network?

Two of the technologies are the mainstream for cellular telephone networks: the global system for mobile communication (GSM) and code division multiple access (CDMA). GSM is a wireless cellular network technology for mobile communication that has been widely deployed in most parts of the world.

What enables computer to transmit data over telephone lines?

A modem is a device or program that enables a computer to transmit data over, for example, telephone or cable lines. Computer information is stored digitally, whereas information transmitted over telephone lines is transmitted in the form of analog waves. A modem converts between these two forms.

What allows to exchange information over the telephone lines?

Answer: A computer network or data network is a telecommunications network which allows computers to exchange data. Network computer devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as personal computers, phones,servers as well as networking hardware.

What is transmission and its types?

There are two types of transmission media, namely guided and unguided. Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves.

What are various technologies used for transmission of data?

Portable devices such as smartphones and tablet computers receive data wirelessly, either over the networks used for cellular phones or over short-range networks using Wi-Fi. See also broadband technology; cable modem; DSL; ISDN; fax; radio; teletype; T1; wireless communications.

What is the technology of the telephone?

In modern telephone networks, fiber-optic cable and digital technology are often employed in such connections. Satellite technology may be used for communication over very long distances.

Which type of switching system is used in telephone network?

circuit switching
The call connection process in the telephone network uses a form of switching, known as circuit switching where a dedicated circuit is set for each telephone call, for example, for the call from the second author to the first author.

What kind of information is transmitted through a telecommunication network?

Merging of speech and data transmission via voice-over IP technology Telecommunication networks are transmission systems enabling information to be transmitted in analogue or digital form between various different sites by means of electromagnetic or optical signals. The information may consist of audio or video data or some other type of data.

How are telephone networks intended to transmit analog signals?

Telephone networks are intended to transmit analog signals. It uses layer 1 (physical layer) of .the OSI model. It is the service to provide physical media. Therefore, telephone networks can carry any type of protocol data. The data transmission speed depends on the performance of the modem and quality of the line.

How are telecommunications networks used in the world?

Telecommunications are the means of electronic transmission of information over distances. The information may be in the form of voice telephone calls, data, text, images, or video. Today, telecommunications are used to organize more or less remote computer systems into telecommunications networks. These networks themselves are run by computers.

Which is the standard protocol for data transmission?

Telecommunication networks for transmitting data formerly used numerous different protocols. Owing to the triumph of the internet, the internet protocol (IP) has gained widespread acceptance as standard protocol for data transmission. Nowadays, virtually all data networks are IP-based.
