The Hyper Text Transfer Protocol (HTTP) works on Layer 7 on the Application layer of the OSI Model.
HTTP Belongs to the Application layer. Other transfer protocols like POP,FTP,SMTP etc also belongs to this layer
Application layer protocols: DNS and HTTP Transport layer protocols: UDP for DNS and TCP for HTTP
Layer 1 - the physical layer
Application Layer
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv

HTTP would fall into either the Application layer or the Presentation layer. There are conflicting views as to which layer protocols like HTTP belong to, but it would be one of those two.

It is work at Network layer.
Application layer protocols: DNS and HTTP Transport layer protocols: UDP for DNS and TCP for HTTP
HTTPS is not a separate protocol, but refers to use of ordinary HTTP over an encrypted Secure Sockets Layer (SSL) or Transport Layer Security (TLS) connection. So it really does not have a place per say, because it's not a protocol it's a hybrid. Or you can say it originates in the Application layer and then finishes in the Presentation layer.
..the two concept of application layer are HTTP and SMTP
Layer 1 - the physical layer
Application Layer
Layer 2 , Data Link Layer

SSL (Secure Sockets Layer) operates primarily at the Transport Layer of the OSI model, which is the fourth layer. It provides secure communication between applications by encrypting the data transmitted over networks. While SSL is often associated with the application layer due to its integration with protocols like HTTP (as HTTPS), its core functionality resides in the Transport Layer.
