Problem Statement
Describe the layers of the TCP/IP model and compare it with the OSI model.
Explanation
The TCP/IP model has four layers: Application, Transport, Internet, and Network Access. The Application layer handles user services like HTTP and FTP. The Transport layer provides end-to-end communication using TCP or UDP. The Internet layer handles routing and addressing through IP. The Network Access layer deals with physical transmission. Compared to the OSI model, TCP/IP merges several OSI layers into fewer practical ones. OSI is more conceptual, while TCP/IP reflects how real networks function.
