Answer to Question 1

The protocols used on the Internet are arranged according to a structure known as the
TCP/IP Protocol architecture. This architecture has five layers, and one or more protocols are
defined at each layer. Data communications and software vendors write computer programs that
implement the rules of a particular protocol. For protocols at the bottom layer, the physical layer,
they build hardware devices that implement the protocol.
The top layer, or the application layer, concerns protocols used between browsers and Web
servers. Hypertext Transport Protocol (http), Simple Mail Transfer Protocol (smtp), and File
Transfer Protocol (ftp) are application-layer protocols.
