A picture is worth a 1000 words!!!

Wireframes are low-fidelity, Screen blueprint, a visual guide usually presented with placeholders for final content, to be filled in at a later point in the design cycle. Wireframes aim to help represent what goes where in a design, without the design team having to spend too much time on the details.

The wireframe depicts the page layout or arrangement of the website’s content, including interface elements and navigational systems, and how they work together.

A mockup is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes.
