Knowing how to troubleshoot a network may be the most vital skill in the field of Information Technology and Network Administration. These positions fall into two very different categories; configuration and troubleshooting. Configuration tasks prepare for the expected and require detailed knowledge of system software, but are normally predictable. Once a system is properly configured there is rarely any reason to change it. In contrast, network troubleshooting deals with the unexpected. These issues are usually unique and sometimes difficult to resolve. Troubleshooting frequently requires knowledge that is conceptual rather than detailed. To approach a problem properly, you need a basic understanding of TCP/IP (Hunt & Thompson, 1998). Internet Protocol version 4 is the current standard “IP” protocol used with Transmission Control Protocol/Internet Protocol (TCP/IP), which is the protocol for Internet addressing. Like the Open System Interconnection (OSI) model, TCP/IP has its own model. The TCP/IP network model represents reality in the world, whereas the OSI model represents an ideal. The TCP/IP network model has four basic layers. The first layer, Network interface layer, deals with all physical components of network connectivity between the network and the IP protocol. Next the Internet layer contains all functionality that manages the movement of data between two network devices over a routed network. Then the Transport layer manages the flow of traffic between two hosts or devices, ensuring that data arrives at the application on the host for which it is targeted. And last, the Application layer acts as final endpoints at either end of a communication session between two network hosts (Tetz).

But, if you are new you will want to have a prior understanding for some of these fixes to eliminate loss of production. Works Cited Hunt, C., & Thompson, R. B. (1998, Oct).
