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.

Inside a device, every address mask is stored as a 32-bit number. When we submit a prefix and an address mask they use a changed form of dotted decimal addressing known CIDR addres
To use a subnet or classless address, table under routers and hosts that have address must keep two pieces of information with every address: the 32-bit address itself and another
