Both are good both have near about same opportunities it depends on you what you want to go for if you are interested in computers then go for computer science if not then take microbiology . If you are interested in something else then you can go for that also

Hello rajesh,
Both of the fields have different career options .
I suggest b.sc computer science is the best option .
It is a 3 year undergraduate program which deals with the applications related to computer  systems and networks .
Now a days world is completely revolving with programming .so ,it is best to study computer science and has the great oppurtunity to enter the real world.
Software field is the most reputed filed having more career options .
Good luck
