Layer 1 – The Physical Layer. The physical layer of the OSI model defines connector and interface specifications, as well as the medium (cable) requirements. Electrical, mechanical, functional, and procedural specifications are provided for sending a bit stream on a computer network. May 02,  · Application Layer Protocols. • An application layer protocol defines how an application processes (clients and servers), running on different end systems, pass messages to each other. • In particular, an application layer protocol defines: – The types of messages, e.g., request messages and response messages. • Application layer provides services to the user, and takes services from Transport layer. • The application layer, however, is somewhat different from other layers. • The protocols can be removed from this layer easily as they only receives services from Transport layer but .

The application layer uses protocols that are implemented within applications and services. Applications provide people with a way to create messages, application layer services establish an interface to the network, and protocols provide the rules and formats that gov- ern how data is treated, as shown in Figure Layer 1 – The Physical Layer. The physical layer of the OSI model defines connector and interface specifications, as well as the medium (cable) requirements. Electrical, mechanical, functional, and procedural specifications are provided for sending a bit stream on a computer network. Describe how common application layer protocols interact with end user applications. Describe, at a high level, common application layer protocols that provide Internet services to end- users, including WWW services and email. Describe application layer protocols that provide IP addressing services, including DNS and DHCP. Interestingly, these protocols work at unique layers of networking model. for example, S/MIME protocol works at application layer, SSL protocol is developed to work at transport layer, and IPsec protocol works at network layer. In this chapter, we can discuss unique methods for achieving security.
