Sir, you won't expect everyone to understand these tecchii... things. As everyone is not CS guy. So I explained in that way.padlast answer is quite long and a little of the track... so i think i can help here a bit...

Sir,padlast answer is quite long and a little of the track... so i think i can help here a bit...
you can safely assume all the hosts that use same default gateway are on same subnet.
so the explaination..
To make routing decisions easier we need a Hierarchical addressing scheme where every host is connected to a gateway and this gateway links all the hosts connected to it with rest of the world.
We have a IPv4 address of 4 octets (yes one octet equal to a byte). Initial design was to have different IP address classes (A,B,C,D and E) but soon there was address allotment problem so CIDR came in place.
Effectively Classless and Classful addresses are no different... both require a gateway on each host.
each packet destined for a host on same subnet never leaves the shared broadcast media (at least in ideal network) and no router is required.
post a message if further details required...
