How do standards fit in with regulations at the federal, manufacturing, and organizational levels? Modern data communication networks are characterized by: ... is the coordinating organization for the US' national system of standards. You can have products that meet the standard, exceed the standard or below a certain standard. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area. Network communication standards ... A network standard defines guidelines that specify the way computers access the medium to which they are attached, the type(s) of medium used, the speeds used on different types of networks, and the type(s) of physical cable and/or the wireless technology used. Data Communication and Computer Network 4 LAN provides a useful way of sharing the resources between end users. Internet is the best example of Computer network that helps you to exchange data between two or more Computers over a network.
