i would like to know what digits of ipaddress define. suppose ipaddress of 192.168.0.59 what these numbers 192 ,168 , 0 ,59 defines. does they have any value??

Not to much you can work from this. Main point is that the provided IP address is class C, to be more precise it is private IP address class C (the range of private C class is 192.168.0.0 - 192.168.255.255) and that you pc can be find on this address in the network you assign to. However this does not give clue on what is network range (dependent on the mask), doesn't provide any data on gateway or your DNS server addressing. So in reality it is not too much.
Can you tell us what you trying to do?
