How data communication and digital communication differ?
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.
Types of communication channel?
The two types of communication channel are analog and digital communication channel. An analog channel uses continuously varying (analog) electrical signals while a digital one uses discrete signals.
The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
What is the definition of symbol strobe in digital communication book?
the sample on which the symbol decision is made
What are Modems used for in Internet?
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...
Why digital communication is known as digital communication?
because it's digital communication.
What are the Advantages of analog and digital communications?
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.
Why is digital communication known as digital communication?
In digital communication message is to be transmitted in digital form. That is why it is called so .
What is the digital revolution and how did it change society what are the benefits of digital media?
The digital revolution refers to the widespread adoption of digital technology in various aspects of society, such as communication, entertainment, and commerce. It has transformed the way people connect, access information, and do business. The benefits of digital media include increased access to information, improved communication, efficiency in work processes, and enhanced creativity and innovation.
What are the advantages of digital communications over analog communication?
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.

Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
