Digital communication is called that because it uses digital signals—usually in the form of binary code (0s and 1s)—to send, receive, and process information. Unlike analog communication, which uses continuous signals, digital communication breaks data into discrete units and transmits it electronically.
This type of communication happens through digital marketing agency in delhil devices like computers, smartphones, and the internet. Examples include emails, text messages, social media, video calls, and online advertising.
It’s called digital because the entire process—transmission, reception, and processing—is handled using digital technology, which allows for faster, more reliable, and more efficient communication.
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference. Advantage of Analog Communication: 1)Transmission bandwidth required is less. 2)No need of synchronization. Advantage of Digital Communication: 1)Digital Communication systems are simpler and cheaper. 2)Using data encryption only permitted user are allowed to detect the transmitted data. 3)Since in Digital Communication, channel coding is used, therefore a large amount of errors may be detected 4)Since transmitted signal is digital in nature,large amount of noise tolerance may be tolerated Disadvantage of Digital Communication: 1)More transmission bandwidth required. 2)Digital Communication needs synchronization in case of synchronous modulation.

bjbl,
Using analogue communication from a digital interface requires some kind of converter to convert your digital data into analogue before it can be sent. This data needs to be converted back into digital by the receiver. Hence a larger amount of work needs to be done. eg: the VGA cable used to connect a PC to a screen is a analogue cable. So all the video signals that are sent out by your PC are converted to analogue first. Hence there is a larger amount of work done. There is also a chance of data being lost during this conversion. If the source signal and the output signal are digital, then there is no conversion required and resulting work required is less. This also means that the receiver doesn't need to convert this data. Hence work done is less and data loss in conversion is also minimal. Although transmitting digital data over long distances also results in some amount of loss. eg: video signals transmitted through DVI or HDMI cables are purely digital. A PC or Blu-Ray player connected to a digital screen using any of the above interfaces doesn't need to convert the signal before sending it. Hence data loss is minimal and resulting picture is sharper and accurate.
because it's digital communication.
process oftransfer of digital data to digital signal is known as line coding
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.

A digital message board.
if the sampling rate is twice that of maximum frequency component in the message signal it is known as nyquist rate
We are currently in the digital age, also known as the Information Age or the Fourth Industrial Revolution. This era is characterized by the widespread use of technology, the internet, and digital communication in various aspects of our lives.

A digital communication system consists of six basic blocks. The functional blocks at the transmitter are responsible for processing the input message, encoding, modulating, and transmitting over the communication channel.
