Answer from AI
The TCP/IP model consists of four main layers:
-
Network Interface (Link Layer) — responsible for data transfer between devices within the same physical network. Includes work with network adapters, data link layer protocols (e.g., Ethernet).
-
Internet Layer — provides routing of packets between networks. The main protocol is IP (Internet Protocol), which handles addressing and delivery of packets.
-
Transport Layer — responsible for data transfer between processes on different devices. Main protocols are TCP (ensures reliable, connection-oriented transmission) and UDP (fast, connectionless transmission).
-
Application Layer — includes protocols that enable interaction between applications, such as HTTP, FTP, SMTP, etc.
Each layer performs its function and interacts with neighboring layers, ensuring data transfer from one application to another across the network.
