Valor,

It depends on what area interests you more...I would try to learn both, however mostly likely than not, you will end up working mostly in one area (either Networking or programming)

Cheers


P.S.
Just my opinion, netwoking is alot easier to master than programming. Anyone can learn networking, however not anyone can write "good" code. Programming to me is like an art.
It's something that's innate that certain people possess. An analogy of learning programming I like to use with my students is:

"Anyone can go to school to learn art or learn how to draw, however not everyone can become a Picasso."
