III Network Communication
Another consideration of setting up a network is, determining how the data will get from one place to another? Somehow, it must be transported. And without agreement on how to transport it, the data isnt moving.
Since the word protocol is frequently used to describe a series of events that need to make something successfully happen, it has been adopted by the network world as well, to describe the structure of the conversation used to transfer data back and forth among machines. In particular, the term transport protocol is bantered about, to refer to the basic member of the protocol family (a group of network protocols) that is being used to transport the data.
Protocols are installed (included) by default when you install the operating system, if a NIC was present. (On newer versions of Windows, they may automagically install when you install the NIC hardware itself.) The protocols installed are then chosen from a list to determine which ones you will use for network communication.
