6.7-1. To which protocol do these fields belong? We learned way back in Chapter 1 that "a protocol defines the format and the order of messages exchanged between two or more communicating entities ..." and throughout the course, we saw many, many different messages being used throughout the protocol stack, each with different fields. In this question, for a given field name in a protocol message (i.e., in an application-layer message, transport-layer segment, network-layer datagram, or link-layer frame), use the pulldown menu to match the field name with the protocol (or pair of protocols) where this field name is used. Each protocol name (or pair of protocol names) in the pull-down menu should be matched to exactly one field description
Networking Model
Networking is a method of linking two or more devices in order to share data, give technical support, and communicate. It refers to the communication between connected computing devices such as desktops, laptops, smartphones, servers, and tablets and also Internet of Things (IoT) devices such as cameras, doorbells, door locks, and various sensors.
Design of the Network System
For a medium and a large scale business around the globe computers and networking plays a major role. With the access of these digital components hardware, all the necessities are interconnected and thus business runs smoothly. As the daily consumption rate of a product is increasing day by day thus the networking factor or the network design of a business is also becoming more complex.
Networking
Networking refers to the communication shared between a group of computers. A group of computers connected to each other for the purpose of sharing resources and information is called a computer network. The first computer network was ARPANET, which stands for Advanced Research Projects Agency Network.
