What is data communication in networking?
Data Communication is a process of exchanging data or information. In case of computer networks this exchange is done between two devices over a transmission medium. This process involves a communication system which is made up of hardware and software.
What are the basics of data communication?
Introduction and Basics of Data Communication Model Data communication involved the following like communication networks, different communication services required, the kind of networks available, protocol architectures, OSI models, TCP/IP protocol models etc.
What is the basics of networking?
The foundations of networking: switches, routers, and wireless access points. Switches, routers, and wireless access points are the essential networking basics. Through them, devices connected to your network can communicate with one another and with other networks, like the Internet.
What are the 4 classifications of data communications?
These are sender, receiver, communication medium, the message to be communicated, and certain rules called protocols to be followed during communication. The communication media is also called transmission media. Figure 11.2 shows the role of these five components in data communication.
What are the 5 components of data communication?
Components of Data Communication System
- Message : This is most useful asset of a data communication system.
- Sender : To transfer message from source to destination, someone must be there who will play role of a source.
- Receiver :
- Transmission Medium :
- Set of rules (Protocol) :
What is data communication with example?

What are the 4 basic elements of communication?
The communication process is made up of four key components. Those components include encoding, medium of transmission, decoding, and feedback.
How does data communication and computer network work?
Data Communication and Computer Network 1 A system of interconnected computers and computerized peripherals such as printers is called computer network. This interconnection among computers facilitates information sharing among them. Computers may connect to each other by either wired or wireless media.
What are the basic characteristics of data communication?
Such information may be used for charging the users of the network based on their usage of the network resources. The effectiveness depends on four fundamental characteristics of data communications 1. Delivery: The data must be deliver in correct order with correct destination. 2. Accuracy: The data must be deliver accurately. 3.
How is data communication and computer network 42?
Data Communication and Computer Network 42 Wireless transmission is a form of unguided media. Wireless communication involves no physical link established between two or more devices, communicating wirelessly. Wireless signals are spread over in the air and are received and interpreted by appropriate antennas.
What kind of degree is needed for data communication?
Completing an associate’s or bachelor’s degree program in computer science or information technology lays the foundation for a data communications career. Data communications, sometimes called computer networking, is the system by which computers or other technologies are connected and share data.
