What are the concepts of data communication and networking?
Basic Data Communication System
Defined as the transmission of digital information between two devices using electronic transmission systems.
Data will be represented either in the form of electrical signals, electromagnetic waves or light.
The source is the device that sends the data message..
What is data communication and networking?
Data communications refers to the transmission of this digital data between two or more computers and a computer network or data network is a telecommunications network that allows computers to exchange data.
The physical connection between networked computing devices is created using either a cable or wireless device..
What is the basic concept of networking and communication?
The field of networking and communication includes the analysis, design, implementation, and use of local, wide-area, and mobile networks that link computers together.
The Internet itself is a network that makes it feasible for nearly all computers in the world to communicate..
What is the basic of network communication?
Networks follow protocols, which define how communications are sent and received.
These protocols allow devices to communicate.
Each device on a network uses an Internet Protocol or IP address, a string of numbers that uniquely identifies a device and allows other devices to recognize it..
What is the basics of data communication?
The term “Data Communication” comprises two words: Data and Communication.
Data can be any text, image, audio, video, and multimedia files.
Communication is an act of sending or receiving data.
Thus, data communication refers to the exchange of data between two or more networked or connected devices..
