What are the major differences among these Masters degree programs?

I'm currently a college student majoring in Linguistics and I've been interested in comp ling for a while. I've been looking at grad school programs in multiple countries and a lot of them are listed under different names. What are the differences, in terms of course content, expectations, potential for career, among Computational Linguistics, Natural Language Processing, and Language and Communications Technologies? Will they all more or less put me on a similar path?
