Commonly used term for white plastic borads with holes in them, designed to allow solderless breadboarding by plugging wires and components into the holes. Pictures here: [
Has a rather undeserved bad reputation because of morons who force thick-lead components into the holes and weaken the spring contacts. Later another engineer has intermittent contacts and concludes that whiteboards are all junk.
Some engineers/technicians make whiteboard circuits that are all neat parallel runs of color-coded wires with 90 degree angles hugging the board. Others like to make a gentle arc from one point to another. Some simply make a rat's nest.
Whiteboards are not suitable for high speed or low capacitance circuits and are clumsy for large designs, but they are great for prototyping small chunks of a design before adding them to a PWB.
If you want to try something *really* interesting, try a SchmartBOARD. [
