I'm approaching the end of Sophomore year in college (Studying Computer Science), and very soon I'm going to have to decide on my concentration, but I honestly don't know what each concentration means.

I basically have two questions:
1. How much influence does your concentration have on your career path? For example, would a video game development company only look at people with a concentration in Game Development?

2.It would be great if you guys could, in a line or two, tell me what sort of jobs am I looking at for each of the concentrations? I need to pick at least two of the 9 below.

- Algorithms and Data Structures
- Artificial Intelligence
- Computer and Network Society
- Computer graphics and vision
- Human-Computer Interaction
- Game Development and Design
- Numeric and Symbolic Computation
- Programming languages
- Systems
