The first major step toward computer system compatibility was the development of the OSI Reference Model in the early 1980s. Developed by the International Organization for Standardization (ISO), the ...

For a decade or two, networks were built using different hardware and software specifications. As a result they were incompatible and it became difficult for networks to communicate with each other.

According to the OSI Model, the session layer is where connections are established, managed, and torn down. For connection-oriented network protocols, understanding how the session layer works, and ...

Agentic AI is changing how systems communicate. Explore why the OSI model may need Layer 8 and Layer 9 for identity, ...

A reference model is a virtual model which defines how communication should take place. It logically divides the processes which are required for the communication into layers. This concept is known ...

The Open Systems Interconnection -- or OSI model layers -- explains the process of endpoint communication via networking, and it is divided into seven different layers based on their functionality.

Morey Haber, Chief Security Advisor at BeyondTrust, is an identity and technical evangelist with over 25 years of IT industry experience. Recently, I was reminiscing with a colleague about unique ...

Whether it’s wired or wireless, most data communications today happens by way of packets of information travelling over one or more networks. But before these networks can work together, though, they ...

To understand the differences between the Transmission Control Protocol/Internet Protocol and the Open Systems Interconnection model, it's helpful to first dig into the individual protocols.
