Step 1: Understand what the OSI model is. It is a framework that describes how different networking protocols interact in seven layers.
Step 2: Identify the layers of the OSI model. They are: 1) Physical, 2) Data Link, 3) Network, 4) Transport, 5) Session, 6) Presentation, and 7) Application.
Step 3: Know what HTTP stands for. HTTP means Hypertext Transfer Protocol, which is used for transferring web pages on the internet.
Step 4: Determine where HTTP fits in the OSI model. HTTP is used by web browsers and other applications to communicate over the internet.
Step 5: Conclude that HTTP operates at the Application layer, which is the topmost layer of the OSI model and is responsible for providing services to end-user applications.
