What else can I help you with?
What would you call a device that works with binary data?
Digital Data is data that is stored in binary, and a Digital Device is any device that works with binary data
What is scrambling in data communication?
to secure analog data is called scrambling in data communication
What is the definition of data communication protocol?
A communications protocol is a system of digital message formats and rules for exchanging those messages in or between computing systems and in telecommunications.
What are data communication terminologies?
data communication terminologies ther are many people distribute about computer
What is frequency in data communications?
If you're talking about electronic communication, both analog and digital communication use a "carrier" frequency to send data. Voice can be across a wire without a carrier, but it's not very efficient. When a carrier frequency is used, the baseline frequency or amplitude can be modulated to transmit the data. In the case of a digital signal, the computer is watching the pulses. any anomaly in the pulses that are expected at a specific time can be converted to data. Data is validated using checksums and parity.
What is the relationship between telecommunication and data communication?
They are both forms of communication They are both a form of communication; data communication is a subset of telecommunication, telecommunication send data between two links by means of electromagnetic. (Like satellite), while data communication means send data by telecommunication, it consists of codes of 0's and 1's. In computer means, Data communication is digital data and telecommunication is equipped to send digital data to receiver.
Define line coding in data communication?
process oftransfer of digital data to digital signal is known as line coding
What is the reason of using aperiodic digital signal in data communication?
bjbl,
How do digital dashboard and data mining applications differ from transaction processing applications?
Digital dashboard and data mining applications do not generate new data, but instead are used to summarize existing data to provide information to management
An open standard that uses digital communication of data, and is accepted and used worldwide?
GSM
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.
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 is often meant by the term 'data transmission'?
A transfer of data from point-to-point is simplified as data transmission. Data transmission can be referred to as digital communication but can include analog data transmission as well.
Why must sound and video input to a PC be converted from analog to digital?
Because in order to preserve the original sound, a digital sampling rate must be twice the frequency of the analog signalAnalog data is smooth and continuous, where as digital data, such as the binary data used in computers, has distinct gradations. The process of producing digital data by measuring data at a series of representative points is called sampling.
What is a open standard that uses digital communication of data and is accepted and used worldwide?
The generic name of such a standard is a "protocol".
Why is digital communication known as digital communication?
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.
