Dear Sir/Madam, I am currently pursuing my third year Bachelor of Engineering in Electronics and Communication.I am very interested in networking and have decided to do a CCNA to pursue my career in that field.But many of my well wishers advised m

Hello deepak........First of all i would like to say that it is very good at your part that you decided to come out of this dilemma in your third year only.This shows how sincere you are regarding your career, good keep it up.Next , it's not necessary that you follow the same path as other do that is jumping into software sector.
I want you to first sit and think which field you are interested in because there is a possibility that the field you choose will continue with you till the rest of your life.

If it comes out to be networking field then according to me you should go for it because this field also have a great growth and future.U can move to "Network security" also.I am going to mention the courses below .I want you to know that may be in the beginning a start in the networking field may not be so attractive or charming like in software side , but after you gain little experience there is no turning back.
You gain go for cisco certification courses like CCNA,CCNP etc. or you can opt for Microsoft Certified Systems Engineer (MCSE) etc.
There is also a benefit that you are still in third year so you can give some spare time for the study of these courses if you find them satisfactory then continue it or you can come back for the preparation of software courses during your final year.
Lastly i want you to know that you must always remember "try to get what you like or you will be forced to like what you get".May be this discussion is productive for you.my best wishes are with you choose the right path.take care
