In general a PCB is classified by the number of copper layers. Boards that consists of 1 or 2 layers are often called: 1-layer PCB is a single sided PCB. 2-layer PCB is a double sided PCB. Boards with no copper layers or with more than 2 copper layers are defined and called by the number of copper layers. Some examples: 0-layer PCB. 4-layer PCB.
