The Internet Protocol Suite, commonly known as the TCP/IP model, is the fundamental framework that allows devices to communicate over the Internet. It consists of four layers—Application, Transport, Internet, and Network Access—each responsible for specific tasks in data communication.
Application Layer: Provides services like email, web browsing, and file transfer.
Transport Layer: Ensures reliable or fast delivery of data using protocols like TCP and UDP.
Internet Layer: Handles logical addressing and routing using IP (Internet Protocol).
Network Access Layer: Deals with physical data transmission over cables, Wi-Fi, etc.
Together, these layers ensure data travels smoothly from one device to another across the globe.
Perfect for students learning networking basics.
