Understanding the TCP/IP Model - A Fundamental Networking Framework
This model serves as the foundation for the internet and plays a
pivotal role in data communication across networks.
The TCP/IP (Transmission Control Protocol/Internet Protocol) model is
a conceptual framework that defines the structure and principles
behind how data is transmitted over networks. It consists of four
layers, each responsible for specific functions in the data
transmission process.
Application Layer: The topmost layer, responsible for managing
end-user applications. Here, protocols like HTTP, SMTP, FTP, and DNS
operate, enabling communication between applications and the
underlying layers.
Transport Layer: This layer deals with end-to-end communication
between devices and provides reliable data delivery. TCP and UDP are
the most well-known protocols within this layer. TCP ensures reliable
and ordered data delivery, while UDP offers a faster, connectionless
alternative, suitable for applications like video streaming or online
gaming.
