Thanks ;)Matthieu said:I am supposed to be sleeping but I re-woke up realising there was something I wanted to do today that I forgot. I'm sending you a pdf that you can use as posters, it is about internet protocols and their encapsulations. I hope you'll like them (now I go sleep). I have other cool stuff like these on networks but unfortunately too big to be uploaded.
A network protocol is a set of rules and standards that govern communication between devices on a network. It specifies how data is transmitted, received, and interpreted, ensuring that all devices on the network can communicate with each other.
Encapsulation is the process of adding a header to data as it moves through a network. This header contains information about the data, such as its source and destination addresses, and helps ensure that the data is delivered to the correct location.
The internet uses encapsulation to transmit data between devices. Each device on the network adds its own header to the data, creating multiple layers of encapsulation. This allows data to travel across multiple networks and reach its destination.
The most commonly used internet protocols are TCP (Transmission Control Protocol) and IP (Internet Protocol). TCP is responsible for breaking data into packets, ensuring they are received in the correct order, and reassembling them at the destination. IP is responsible for addressing and routing the packets to their destination.
Port numbers are used to identify specific applications or services on a device. They allow multiple applications to run simultaneously on the same device without interfering with each other. Port numbers are also used for communication between devices on a network, ensuring that data is delivered to the correct application or service.
