Some devices/technologies used in data communications are known as data communication equipment (DCE) and data terminal equipment (DTE). DCE is used at the sending node, and DTE is used at the receiving node. Another way to talk about different types of data communications is to refer to the...
That is, they distill the basic structure of communication into a more digestible form. They also identify the various elements involved and how different parts of the process interact or are interrelated. The first majormodelfor communication, the Shannon-Weavermodel, was developed by Claude Shannon...
Types of data model Logical and physical data models are the most widely used data model types. What is the main difference between logical and physical models? In short, the logical data model is an abstraction of the physical data model: it reflects the business point of view and business...

The Seven Layers of the OSI Model The OSI Model serves as a foundational framework in the field of networking, defining the fundamental functions and responsibilities necessary for successful data communication. Comprised of seven distinct layers, this model guides the way data is transmitted, re...
The OSI model provides a framework to allow different computer systems to communicate with each other. Learn more about the 7 Network layers of the OSI reference model.
There are seven abstraction layers that make up the OSI model. Communication from one person to another goes from Layer 7 to Layer 1. Each layer performs a specific job before it sends the data on to the next layer. Layer 7 - Application layer The application layer is the closest to th...
models can generally be divided into three categories, which vary according to their degree of abstraction. The process will start with a conceptual model, progress to a logical model and conclude with a physical model. Each type of data model is discussed in more detail in subsequent sections:...
Data transmission or communication is the process of transferring digital or analog data from one device to another in a point-to-point, point-to-multipoint, or multipoint-to-multipoint environment. Organizations choose data transmission systems to ensure smooth data flow via information networks. ...
With the speed of digital transformation, companies need to find new ways to improve business communication and collaboration. Learn more about Unified Communications.
