My understanding:
Wireframe is part of the design stage and is a graphical layout of the expected final product. Non-interactive and can be drawn by hand or using a drafting package. Placeholders instead of actual content (e.g. boxes with an X in them to indicate images, wiggly lines to indicate text).
A low fidelity prototype can involve some element of interaction and has more detail. I suppose it would be akin to an “alpha” version. The images are actual images that will be used, text is in place and links “work”. However, it still doesn’t need to be functional software. A paper-based version could be produced, and demonstrated to the end user. Tap on the hand-drawn “link” and the next page is shown – manually interactive, if that makes sense.
I’ll confirm this, but that’s my Monday morning / not slept enough understanding.
