Traditional portfolios are something that you can carry around with you. (Port=to move about, Folio=pages, or a book of pages. Portfolio=a book of pages you can carry about). Most commonly, something like this for bringing to an interview:
Looking at your images you should decide what size portfolio is best for you. If a majority of your work is large, but would look truncated if it were photographed and reprinted at a reduced size you may need to acquire a large specialty portfolio. These can be purchased, but also can be made by you if you either want a custom look to it or are simply trying to save money.
Then you should follow advice from your discipline on layout and needed contents. You professor(s) in your area will likely have good advice on which of your materials to put in, and leave out. Simple, short, clear labeling is always appreciated regardless of your area of work!
You can also find lots of advice on a number of types of portfolio online
