As I have learned about this from IT school I have learned about the consequences. Digital communication has a lot of benefits, which is why it is becomming the main mode of communication. But as witg everything there are a few downfalls. One major downfall is when you have spyware or a virus or you have been hacked. There are also devices that allow you to "intercept" these messages. With these means, one can also recieve your message. Basically someone can monitor what you are saying. Which can be used for blackmail, or corporate espionage. Also police sometimes intercept messages if you are a suspect. Another negative is that if your computer is exposed, someone can take it, view messages and also get passwords if theyre skilled enough. If you have saved passwords they can walk right into your accound, lets say bank account. Then they can steal your money as well as information. These are the major negatives, if you wish me to go on I will reply with more information

Why digital communication is known as digital communication?
because it's digital communication.
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 are some impacts on the developments of communication?
the most important developement has been digital satellite communication that allows communication any where in the world, in real time.
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.
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
What are digital communication books related to uptu syllabus according to 6 sem?
Some recommended digital communication books that align with the UP Technical University (UPTU) syllabus for the 6th semester include "Principles of Communication Systems" by Taub and Schilling, "Digital Communications" by Simon Haykin, and "Digital Communications: Fundamentals and Applications" by Bernard Sklar. These books cover topics such as modulation techniques, signal encoding, communication channels, and digital transmission systems, which are commonly included in the 6th-semester syllabus for digital communication courses.
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.
What digital communication device interfaces refrigerators with the Internet?
A digital message board.
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.
What are the advantages of using digital signals and why?
* Digital signals suffer less interferences than analogue signals. This means that when you listen to a digital signal you won't hear a hissing sound, as within digital signals regenerator circuits are used to clean "noisy" pulses. * Digital signals can be made very short so more pulses can be carried around each second, which means more information can be passed on.
Analog & digital communication?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
