The distance over which data moves within a computer may differ from a few thousandths of an inch, as is the case within a one IC chip, to as much as lot of feet along the backplane of the main circuit board. Over these small distances, digital data might be transmitted as direct, two-level electrical signals over simple copper conductors. Except for the fastest computers, circuit designers are not very concerned about the shape of the conductor or the analog characteristics of signal transmission.
Large data packets result in fewer load because a smaller part of the packet is used for header information. Optimum networks use 4kB data packets or larger. Large data packets
Packet Cost Both distance vector and link state routing are lowest algorithms. Tow factors govern how cost is applied to packets in determines a route. Cost is a
