Lab 3.1 – 3.4 Summaries
Lab 3.1 The network reference models refer to the TCP and the OSI models of communication between machine and server. The TCP model includes a 5 layer process, whereas the OSI model has a 7 layer process. Each is important for sending and receiving data.
Lab 3.2 The OSI reference model is a networking model that serves as communication between client and server by means of a 7 layer process. The first layer is the physical layer in which you have the actual connection type. The second layer is the data link which contains the actual data being sent. The third layer is the network layer that grabs the IP address of the receiver. The forth layer transports the data from sender to receiver. The fifth layer sets up which software should run the data. The sixth layer determines how the data is presented. The last layer opens the application that the data is displayed on.
Lab 3.3 The TCP model is exactly the same thing as the OSI model except for the fact that the last 3 layers are crammed into 1. The first layer is the physical layer in which you have the actual connection type. The second layer is the data link which contains the actual data being sent. The third layer is the network layer that grabs the IP address of the receiver. The forth layer transports the data from sender to receiver. The fifth layer sets up which software should run the data, determines how its presented and loads the proper application.

Lab 3.4 Data link connections can come in all shapes and sizes and are a means in which one local business or residence connects with an outside party, either another business or another residence. Typically if you want to cover a large area, a WAN connection is necessary and that takes data you want to send and routes it through a series of WAN hubs to eventually reach the target…...
