Sep 8, 2023 · This Data Communication tutorial is designed for both beginners and experienced professionals, covering basic and advanced concepts of data communication. It includes topics such as the basics of data communication, OSI Model, TCP/IP Model, addressing, and more.

Jan 20, 2025 · The OSI (Open Systems Interconnection) Model is a set of rules that explains how different computer systems communicate over a network. OSI Model was developed by the International Organization for Standardization (ISO). The OSI Model consists of 7 layers and each layer has specific functions and responsibilities.

Data communications are the exchange of data between two devices via some form of transmission medium such as a wire cable. It includes the transfer of data ,the method of transfer and the preservation of data during transfer process.

Explore the fundamentals of data communication in computer networks. Understand key concepts, protocols, and technologies that drive effective data exchange.

Mar 27, 2022 · In networking, we need a data communication model to transfer data from one station to another. Data cannot be transferred from one end to another without a communication model. Therefore, the data communication model includes sender, transmitter, communication channel, receiver, and destination.

Explore the various computer network models including OSI and TCP/IP models, their layers, and functionalities in this comprehensive overview.

Feb 28, 2025 · Data communication models help us understand how data is transmitted between devices. There are two main models: the OSI model and the TCP/IP model. These models provide a framework for organizing and standardizing communication processes.
