What is Application?
The Application layer is the seventh and topmost layer of the OSI model, where end-user software interacts with the network. It provides network services directly to applications, enabling functions like web browsing, email, file transfer, and domain name resolution. Protocols such as HTTP, FTP, SMTP, and DNS all operate at this layer.
