I can not define subnets more then that Wiki link.

In short subnets are needed to tell, an IP address belongs to which class which are A,B,C (popularly) and D,E (research).

We need these classes for...

1. Better management of IP addresses as there can be 16 million addresses.

2. Security , as computer with A class IP can only talk to computers of same class unless specifically given instructions at the network level by Networks Admin.
