Usability is how easy an object is to use. The object can be almost anything, including a machine, tool, process, book, software application or website. Anything that a person can interact with should be usable. In the case of websites and software applications, usability has been defined as the ease at which an average person can use the software or website to achieve specific goals.
Usability is comprised of learnability, memorability, efficiency, satisfaction and errors. Learnability is how easy it is for a new user to accomplish tasks the first time they visit your website. Memorability is how easy it is for someone to come back to using your website after they haven't used it for a period of time. Efficiency is how quickly users can complete tasks on your site after they are familiar with its use. Satisfaction is whether users enjoy the design of your site and errors refers to the number of errors users make when they use your site, the severity of the errors and how easy they are to recover from.
