81) Explain each of the three important concepts behind the Federal Networking Council'sdefinition of the termInternet. Explain how each of these technologies contributes to thefunctioning of the Internet today.Answer: The three important concepts in the Federal Networking Council's definition of theInternet are packet switching, the TCP/IP communications protocol, and client/server computing.Packet switching is a method of slicing digital messages up into parcels that are sent alongdifferent communications paths as they become available. The packets travel from routercomputer to router computer and are then reassembled at their destination point. These routersare special purpose computers that interconnect the thousands of computer networks that makeup the Internet. Since this method does not require a dedicated circuit, it makes use of anyavailable spare capacity on any one of several hundred circuits enabling nearly full use ofavailable communication lines and capacity.Transmission Control Protocol/Internet Protocol (TCP/IP) is the universally agreed upon methodfor breaking the messages up, routing them to their destination, and reassembling them. The TCPprotocol, or set of rules, specifies how messages should be formatted, ordered, compressed, anderror-checked. It also stipulates the method devices on the network will use to indicate that theyhave stopped sending and/or receiving messages and sometimes specifies the transmission speedas well. The IP protocol provides the addressing scheme for the Internet. Each computerconnected to the Internet must be assigned an Internet Protocol address so that it can send andreceive TCP packets. At present, each time a home user signs on to the Internet they aretemporarily assigned one of these 32-bit numbers by their ISP.Client/server computing involves very powerful personal computers that are connected togetherin a network along with one or more server computers. These client computers can display richgraphics, store large files, and process graphic and sound files. The server computers arespecifically allocated to common functions that all of the client computers need such as storingfiles and supplying software applications, and utility programs.
