Question

Hypertext Transfer Protocol (HTTP) for web browsing, File Transfer Protocol (FTP) for transferring files, and Simple Mail Transfer Protocol (SMTP) for email transmission are examples of which OSI model layer?

a. Data Link Layer
b. Application Layer
c. Presentation Layer
d. Session Layer

Answer 1

HTTP, FTP, and SMTP are protocols that operate at the Application Layer of the OSI model, enabling software applications to communicate over the network.

Step-by-step explanation:

Hypertext Transfer Protocol (HTTP) for web browsing, File Transfer Protocol (FTP) for transferring files, and Simple Mail Transfer Protocol (SMTP) for email transmission are examples of protocols found in the Application Layer of the OSI model. The Application Layer is responsible for providing network services to applications, which means it enables software applications to interact with the network. When you use a web browser or an email client, it is the Application Layer protocols like HTTP and SMTP that enable these software applications to send and receive data over the internet.
