Your "commute" is the experience that you have traveling to work every day. You can describe a commute as short or long, easy or difficult.
I like it a lot. The commute is easy, the people there are nice, and I'm doing something that I really care about.
You can commute by car, by train, or by bus.
If you walk to work, you usually wouldn't use the word "commute" to describe how you get to work.
