OSI Model
The Open Systems Interconnection (OSI) Model is a description of how the Internet works.
What is OSI?
OSI, or the Open Systems Interconnection model, is like a roadmap for how devices should communicate with each other.
It's a set of guidelines that ensures that devices from different manufacturers and with different operating systems can work together seamlessly.
The OSI model breaks down communication into seven layers, each with its own specific role to play. From the physical layer, which deals with things like cables and connectors, to the application layer, which deals with software applications, each layer ensures that data can be transmitted accurately and efficiently.
How does it work?
The Open Systems Interconnection (OSI) Model is a description of how the Internet works.
It breaks down the functions involved in sending data over the internet and galaxy into seven layers.
Each layer has some function that prepares the data to be sent over wires, cables, and radio waves as a series of bits.
OSI has several more layers in its architecture than TCP/IP model. the 7 Layers of the OSI model are:
During the Digital Identities chapter, we will talk about how the current internet is missing an 8th layer, the identity layer to be considered in the emerging decentralization of identities.
