“The term “tabernacle” is sometimes used to refer to one part of a larger complex: the tent-like structure that stood within a court enclosed by linen curtains. At other times the term describes the entire complex.” http://www.biblestudytools.com/dictionary/tabernacle/ This site describes it this way and goes into much more detail about the tabernacle represented and was used for.

Has a great image of what they think it looked like and explain it as “Tabernacle means “tent,” “place of dwelling” or “sanctuary.” It was a sacred place where God chose to meet His people, the Israelites, during the 40 years they wandered in the desert under Moses’ leadership. It was the place where the leaders and people came together to worship and offer sacrifices.”
