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.
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 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.
How is a modem facilitats communication different between computer?
a modem is a tool which can change analog sinal to digital signal and vice-versa. when the communication has to take place between the two computers then there is involvement of wires or some wireless technology. if communication exists between then it is through analog signals and computer can accept only digital signal. so,basically modem changes the analog signal to digital when the data is to be received at computer's end and hence it works and facilitates the commmunication between two or more computers.
What is a basic digital wave form?
A basic digital waveform represents discrete levels of voltage over time, typically characterized by two primary states: high (1) and low (0). These waveforms are often visualized as square waves, where the signal switches between these two levels at regular intervals. Digital waveforms are crucial in digital electronics and signal processing, as they encode information for transmission and processing in digital systems. Common examples include clock signals in microcontrollers and data signals in digital communication.
What is Two-step communication?
Two step flow communication is the communication that goes through two channels.
What are the two general form or classification of communication?
Two forms of communication are spoken communication and written communication.
What are types of telecommunication networks?
telecommunication industry structure, telecommunication companies, authorities in the CaribbeanTelephoneTelevisionTelegraphTell a WomanRadioInternet
What is dyatic communication?
Communication between two or more entities; two-way communication
What is Two-step communication model?
Two step flow communication is the communication that goes through two channels.
What is Two step communication model?
Two step flow communication is the communication that goes through two channels.
What is data communication?
I would define data communication as the transfer of information between two points, either via an analogue (sine wave) electrical signal. or digital (binary ) signal via electrical pulses or optically via light pulses
