Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that

allows computers to exchange data

.

What is data communication and give at least three examples?

Data communications refers to the sharing of a virtual message.

Electronic communications

, like emails and instant messages, as well as phone calls are examples of data communications.

What is data communication medium?

Communication medium refers

to the physical channel through which data is sent and received

. … The speed of data transmission or data rate depends upon the type of medium being used in the network. There are basically two types of networks: Wired network. Wireless network.

What is the characteristics of data communication?

The effectiveness of a data communications system depends on four fundamental characteristics:

delivery, accuracy, timeliness, and jitter

.

What is the example of data communication?

For example, a common example of data communications is

a computer connected to the Internet via a Wi-Fi connection

, which uses a wireless medium to send and receive data from one or more remote servers.

What are the 5 components of data communication?

• Message: The message is the information (data) to be communicated. …
• Sender: The sender is the device that sends the data message. …
• Receiver: The receiver is the device that receives the message. …
• Transmission medium: …
• Protocol:

What is data transmission speed?

Transmission speed is

the rate at which data packets cross a computer network from one server to another

. Transmission speed is typically measured in megabits per second (Mbps), which equals one million bits per second, although gigabit and even terabit speeds are becoming common. … They vary in Mbps.

What is the medium used when the data is physically passed or transferred from one computer to another?

A physical medium in data communications is the transmission path over which a signal propagates. Many different types of transmission media are used as

communications channel

. In many forms of communications, communication is in the form of electromagnetic waves. … This term can apply to both guided and unguided media.

How is data transmitted over the Internet?

Data travels across the internet

in packets

. … Packets will travel from one machine to another until they reach their destination. As the packets arrive, the computer receiving the data assembles the packets like a puzzle, recreating the message. All data transfers across the Internet work on this principle.

Which of the following are used as a typically transmission medium in data transmission element?

They are the most widely used Transmission Media.

Twisted Pair

is of two types: Unshielded Twisted Pair (UTP): UTP consists of two insulated copper wires twisted around one another.

Which of the following medium is not as a channel for digital transmission?

A modem

is not a transmission medium out of the given options. There are two forms of media of transmission, that is directed and unguided. Cables such as twisted pair cables, coaxial cables, and fiber optic cables are guided transmission devices.

What kind of transmission medium is most appropriate to carry data?

Answer: The

optical fiber

is made of glass or plastic.

What are the data communication methods?

• Simplex: Data travels in one direction (from A to B). …
• Half-duplex: Data travels in one direction (from A to B) and then the other direction (from B to A) but not at the same time. …
• Full-duplex: Data can travel in both directions at the same time.

Which communication medium requires line of sight Mcq?

What is light sight?

We are able to see because light

from an object can move through space and reach our eyes

. Once light reaches our eyes, signals are sent to our brain, and our brain deciphers the information in order to detect the appearance, location and movement of the objects we are sighting at.

Which of the following communication media carries light signals?

Optical communication, also known as optical telecommunication

, is communication at a distance using light to carry information. It can be performed visually or by using electronic devices.

What is communication in data communication?

The term “Data Communication” comprises two words: Data and Communication. Data can be any text, image, audio, video, and multimedia files. Communication is an act of sending or receiving data. Thus, data communication refers

to the exchange of data between two or more networked or connected devices

.

What is the components of data communication?

There are three broad categories of communications system components:

(1) transmission media, (2) hardware, and (3) software

. Transmission media include both bounded media (twisted-pair wire, coaxial cable, optical fiber) and unbounded media (microwave, satellite, and infrared).

What are the examples of medium of communication?

In a nutshell, communication channels are mediums through which you can send a message to its intended audience. For example,

phone calls, text messages, emails, video, radio, and social media

are all types of communication channels.

Which of the following communication medium supports highest data rate?
