Final answer:
The five layers of TCP/IP are Physical, Data Link, Network, Transport, and Application.
Step-by-step explanation:
The TCP/IP protocol suite consists of two main protocols: TCP (Transmission Control Protocol) and IP (Internet Protocol). TCP is responsible for breaking data into packets, ensuring their reliable delivery, and reassembling them at the destination. IP is responsible for addressing and routing the packets.
The TCP/IP protocol stack is organized into five layers:
- Physical layer: This layer defines the physical medium and the mechanism used to transmit bits between devices.
- Data Link layer: This layer is responsible for node-to-node communication over a physical link, ensuring error-free transmission of frames.
- Network layer: This layer handles the addressing, routing, and fragmentation of packets across multiple networks. IP operates at this layer.
- Transport layer: This layer provides end-to-end communication between hosts, ensuring reliable delivery and flow control. TCP operates at this layer.
- Application layer: This layer supports specific applications and protocols. Examples include HTTP, FTP, and SMTP.
