Lesson 5 Review: Networking Models, Traffic and Devices
The purpose of this activity is to reinforce what you have learned so far about local area networks technologies.
1. Describe the three modes of communication available on a network. (Minimum word count: 60)
They are simplex, half-duplex, and full duplex. In simplex communication, data travels only in one direction, much like a PA system. While the half-duplex allows travel in two different directions, but only one direction at a time, much like a walkie talkie. The full-duplex communication allows data to travel in ...view middle of the document...
The PDU consists of the payload or original information along with the header that is added in Layer 7 of the OSI.
4. List three practical functions of the OSI model. (Minimum word count: 60)
The OSI practical functions are it describes the process of packet creation. It also explains the framework used to connect different types of systems, meaning it allows communication between client and servers even if on different operating systems and applications. All that is needed is a common protocol like a TCP/IP. It gives developers necessary universal concepts so they can develop and perfect protocols that work with multiple systems and network products developed by other vendors.
5. Describe a collision domain. (Minimum word count: 70)
A collision domain is an area in a network where a group of network devices compete for the access to the transmission medium. When two devices attempt to transmit at the same time, their transmitted frames collide and are destroyed. The greater number of collisions, the less efficient the network. Large networks are frequently divide into distinct collision domains through the use fo a networking device such as a switch, bridge or router. Dividing a network into distinct collision domains reduces the number of collisions in the overall network and keeps it functioning efficiently.
