In networking ,the most commonly used model is 5-layer model besides OSI model and 4 -layer model with some changes made to 5-layer. To establish this connection, it starts with the physical layer, which makes connections possible through the cabling, computers, routers and server hardware that are physically or wirelessly connected. This layer uses various protocols depending on the applications.For example, HTTP(Hyper Text Transfer Protocol) is used by the web-servers and the web-pages.In case of OSI model, this layer is split into Session layer , Presentation Layer and Application Layer. get that data. has occurred and that the device We'll explore how encapsulation works and how protocols such as ARP allow different layers of the network to communicate. Later on in this lesson when we introduce ARP or address resolution protocol, you'll see that the way that nodes learn about each other's physical addressing isn't translatable to anything besides a single network segment anyway. How many bits is a port field? network A. The Transport layer establishes the connection between applications running on different hosts. frames.
