Understanding Network Protocols

Application Layer

Protocols that provide network services directly to end-user applications such as HTTP, FTP, SMTP, and DNS.

Transport Layer

Protocols that ensure complete data transfer with TCP providing reliable delivery and UDP offering connectionless communication.

Network Layer

Protocols responsible for packet forwarding and routing, including IP which determines the best path for data delivery.

Data Link & Physical

Protocols that handle communication between adjacent network nodes and the physical transmission of data bits.
