    There has to be a communication path or multiple paths for data travel in order for communication to work in a network. Information flows from one place to another and back using these paths. This is also know as switching.

    In 4-5 paragraphs, complete the following:

    -Compare and contrast the three types of switching methods: store-and-forward, cut-through, and fragment-free.
    -Describe a situation in which each of these switching methods would be used.
    -Explain why Spanning-tree Protocol (STP) is important in switching.

    //Store and forwarding, cut-through and fragment free are all modes of LAN switches ensuring the safe error free transmission of the frame. In this paper, we will explain the basic functioning of the switches. It will provide a basic comparison between all the different modes of switches.//

    As the name suggests Store and Forward switching method first receives the entire data, stores it and then it is checked against any error under the CRC (cyclical redundancy check) framework and in the absence of any error, it is forwarded to its destination otherwise it is chucked out. Cut- Through switching method, it tests only the initial portion of the data, basically up to its MAC destination and forwards it very quickly. The Fragment Free switching method also known as composite of store and forward and cut- through switching method, performs the switching function only when the size of the frame is up to 64 bytes at least (Network Connectivity, 2010)
