In the given solution , while calculating transmission time why 8 is not multiplied i.e. Length = 2000Byte = 2000 * 8 bits formula is not used.

we have a network with ID 20.255.0.0 and a network with ID 20.0.0.0 they both will have the same directed broadcast address i.e. 20.255.255.255 so when a data packet is sent with DBA 20.255.255.255 to which network this data will be sent ?

Why class A network addresses has a restraint of "not taking initial and final network address" , while other classes won't
Since we know that class A has the range of its network address (first octet) from 1 to 126 , since we wouldn't choose 0 and 127 .. but in class B the range is from 128 t...
