Mouse : A computer mouse with the most common features: two buttons (left and right) and a scroll wheel, which can also act as a third button. A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface. The first public demonstration of a mouse controlling a computer system was in 1968. Originally wired to a computer, many modern mouse are cordless, relying on short-range radio communication with the connected system. Mouse originally used a ball rolling on a surface to detect motion, but modern mouse often have optical sensors that have no moving parts. In addition to moving a cursor, computer mouse have one or more buttons to allow operations such as selection of a menu item on a display. Mouse often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input.

A Uniform Resource Locator (URL), colloquially termed a web address, is a reference to a web resource that specifies its location on a computer network and a mechanism for retrieving it.

Humanware is hardware and software that emphasizes user capability and empowerment and the design of the user interface. The process of building humanware generally consists of these steps: 1. Define users (age, mindset, environmental context, previous product experience and expectations, and so forth) and what they really want to do. 2. Identify tasks they will need to do or capabilities they will want 3. Specify usability objectives (if possible, these should be measurable, such as how long to do something or how many mouse clicks to get to a specified task point) for each task or capability. 4. Build a prototype of the user interface (it can be a paper or simulated prototype if time is short) 5. Test and verify or correct the prototype 6. Provide the prototype and usability objectives to the program designers and coders. Source : techtarget.com
