Transmission Control Protocol/Internet Protocol (TCP/IP) Model

The TCP/IP Model is a set of rules that enables computers to communicate over networks like the internet. It has four layers: the link layer (handling physical connections), the internet layer (routing data between devices), the transport layer (ensuring data is transferred reliably, like TCP), and the application layer (where users interact through apps and websites). These layers work together to ensure data travels accurately from one device to another, regardless of the hardware or network technology involved, allowing seamless communication across different systems worldwide.
