What is the OSI model?

The OSI model is a framework that standardizes communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology.

How many layers are in the OSI model?

There are seven layers in the OSI model.

What are the first three layers of the OSI model?

The first three layers are the Application layer, Transport layer, and Network layer.

Why is the OSI model important?

It helps ensure that different systems can communicate with each other effectively.

What does the Physical layer do?

The Physical layer transmits raw bitstreams over a physical medium.

Résumé

TLDRThe video discusses the OSI (Open Systems Interconnection) model, which is a framework developed to standardize communication across different vendors. It explains the purpose of the OSI model, which is to facilitate communication between devices from different manufacturers. The presenter outlines the layers of the OSI model, emphasizing the first three layers: Application, Transport, and Network. The video illustrates how data is processed through these layers, from the application level down to the physical transmission of data. The importance of understanding these layers for practical networking is highlighted, particularly for troubleshooting and effective communication.

Chronologie

00:00:00 - 00:06:41
In this video, we learn about the OSI layer, which stands for Open Systems Interconnection. Developed by the International Organization for Standardization, the OSI model standardizes communication across different vendors, allowing devices to communicate effectively. The OSI model consists of seven layers, and the presenter humorously recites the order of these layers. The video explains how data flows from the application layer down to the physical layer, detailing how data is formatted and transmitted over a network. The focus is primarily on layers 1 to 3, which are visible and manageable for users. The presenter concludes by encouraging viewers to understand the OSI layer and hints at continuing with further material in the next video.
