Usability is the understanding it takes to make something work, its "ease of use." Web site usability is the understanding of how an individual navigates, finds information and interacts with your web site.
Usability addresses the relationship between tools and their users. In order for a tool to be effective, it must allow intended users to accomplish their tasks in the best way possible. The same principle applies to computers, web sites and other software. In order for these systems to work, their users must be able to employ them effectively.
