When you think of a university campus, you would generally think of the above image. Yes. This is an example of an actual tangible university campus. A campus could be defined as the grounds and the buildings of an institution.
I conduct my research and study from the comfort of my own home. Therefore, my home is my campus. The great thing about this concept is the fact that I don't have to pay extra money for rent or to buy a building to act as a university campus.
