MOUSE
In computing, a mouse ( plural mice, mouse devices, or mouse ) is a pointing device that functions by detecting two-dimensional motion relative to its supportingsurface. Physically, a mouse consists of a small case, held under one of the user's hands, with one or more buttons. It sometimes features other elements, such as " wheels ", which allow the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse's motion typically translates into the motion of a pointer on display, which allows for fine control of a Graphical User Interface.
The name mouse originated at the Stanford Research Intitute, derives from the resemblance of early models ( which had a cord attached to the rear part of the device, suggesting the idea of a tail ) to the commmon mouse.
The first marketed integrated mouse - shippedas a part of a computer and intended for personal computer navigation - came with the Xerox 8010 Star Information System in 1981.

Etymology and Plural
The firat Known publication of the term " mouse " as a pointing device is in Bill English's 1965 publication " Computer-Aided Display Control ".
The Compact Oxford English Dictionary ( third edition ) and the fourth edition of The American Heritage Dictionary of English Language endorse both computer mice and computer mouses as correct plural forms for computer mouse. The form Mouse, however, appears most commonly, while some generic pointing devices. The plural mouses treats mouse as a " headless noun ".
Two manuals of style in the computer indutry - Sun Technical Publication's Read Me First: A Style Guide for the Computer Industry and Microsoft Manual of Style for Technical Publications from Microsoft Press - recommend that technical writers use the term mouse devices instead of the alternatives.
Application Of Mice In User-Interface
Computer-users usually utilize a mouse to control the motion of a cursor in twa dimensions in a graphical user interface. Clicking or hovering can select files, programs or actions from a list of names, or ( in graphical interface ) through picture called " icons " and other elements. For example, a text file might be represented by a picture of a paper notebook, and clicking while the pointer hovers this icon might cause a text editing program to open the file ia a window. ( see also point-and-click ).
User can also employ mice gesturally; meaning that a stylized motion of the mouse cursor itself, called a " gesture ", can issue a command or map to a specific action. For example, in a drawing program, moving the mouse in a rapid " x " motion over a shape might delete the shape.
Gestural interface occur more rarely than plain pointing-and-clicking; and people often find them more difficult to use, because they require finer motor-control from the user. However, a few gestural conventions have become widespread, including the drag-and-drop gesture in which :

Gestural interface occur more rarely than plain pointing-and-clicking; and people often find them more difficult to use, because they require finer motor-control from the user. However, a few gestural conventions have become widespread, including the drag-and-drop gesture in which :
- The user presses the mouse button while the mouse cursor hovers over an interface object
- The user moves the cursor to a different location while holding the button down
- The user releases the mouse button
For example, a user might drag-and-drop a picture representing a file into a picture af a trash-can, thus intructing the system to delete the file.
Other uses of the mouse's input occur commonly in special application-domains. in interactive three-dimensional graphics, the mouse's motion often translates directly into changes in the virtual camera's orientation. For example, in the first -person shooter genre of games ( see below ), players usually employ the mouse to the control the direction in which the virtual player to look up, revealing the view above the player's head.
when mice have more than one button, software may assign different functions to each button. Often, the primary ( leftmost in a right-handed configuration ) button will bring up a menu of alternative actions applicable to that item. For example, on platforms with more than button click, will bring up a contextual menu of alternative actions for that link in response to a click with the tertiary ( middle ) mouse button
