Academic fields often don't try to keep up with the lingo and small technical issues.
In theory, you should be being taught nice general knowledge that will be useful for a long time, and more importantly you are being taught how to learn.
The company could train them, or they could hire people who know how to learn. I know reems of information about colour theory, dispite having never taken a graphics course at a university: because I've used it and worked with people who have used it.
Want to be employable? Read a good technical book every month, and make sure you can apply it. With toy problems at the least, and ideally directly on your job. After 10 years of doing this, you'll know a huge amount more than you ever learned in university.
Then again, this is coming from someone who reads "Internet Core Protocols" for fun.
