Understanding the Application Layer Protocols in the TCP/IP Model: HTTP and SMTP

Which two protocols belong in the TCP/IP model application layer?

In the TCP/IP model, the two protocols that belong to the application layer are:

1. Hypertext Transfer Protocol (HTTP): This is the protocol used for transferring hypertext documents on the World Wide Web. It is the foundation of data communication for the web and allows for the retrieval and display of HTML pages, images, videos, and other resources.

2. Simple Mail Transfer Protocol (SMTP): SMTP is responsible for sending and receiving email messages. It is used for transferring email from the sender’s email client to the recipient’s email server and vice versa. SMTP ensures that emails are properly routed and delivered across different networks.

Apart from these two protocols, other application layer protocols include File Transfer Protocol (FTP) for downloading and uploading files, Domain Name System (DNS) for translating domain names into IP addresses, Simple Network Management Protocol (SNMP) for managing and monitoring network devices, and many others.
