Definition:- A mouse is used as a computer input device to control the location of a cursor on a video display connected to the computer
Computers are used by more and more people every day for use at home and at the office. Modern desktop computers provide users with user-input mechanisms that are well suited for the applications that run on these computers. The use of a hand operated pointing device for use with a computer and its display has become almost universal. A computer user manipulates a pointing device to change the position of a cursor or other object on a computer display, or to select objects on the display. The physical movement of the pointing device results in a similar movement of the cursor and/or object on the display. Data input devices have been used since the sixties as a graphic user interface (GUI) to allow a user to input certain information into computer systems and to modify or operate on images or information displayed on an output screen attached to the computer system. Examples of input devices are trackballs, joysticks, writing pens, computer mice, and graphic tablets. These input devices translate motion applied to the input device into digital data bits delivered to the computer system and allow an individual to communicate with computers. Most computer systems, as for example general purpose computers such as portable computers and desktop computers, receive input from a user via an input device. Different types of mouse devices have been integrated into laptop or notebook computers, such as: pointing sticks, glide points, and track balls, to provide the user the convenience of travel without the necessity of multiple attachments. For desktop computers, the ubiquitous computer mouse constitutes the large majority of pointing devices. A computer mouse is widely used as a pointing device for a personal computer, for controlling movement of a cursor over the display screen of the computer's monitor. Generally speaking, input/output devices receive input from a user or another source and/or provide output to a user or anther source. Keyboards and computer mice are typically considered input devices because they receive input from a user but provide no output to the user. To a personal computer (PC) user, the mouse is one of the basic devices utilized to input data into the PC, the other being the keyboard

Mouse History
Aside from the occasional trackball, almost every desktop computer has a mouse connected to it. However, the mouse has not always been the most common pointing device, and it has gone through many changes during its nearly thirty-year history. Keep reading to learn more about the history of computer mice...
Pre-1985: Computer mice began to appear in the early 1980s, but many computers required an additional expansion board/card to use them during this period of history. Other pointing devices like trackballs, joysticks, and light pens were more common. According to wikipedia.org, Xerox made history by introducing the first computer with a mouse and a graphical user interface in 1981, but it took years for other brands to begin doing the same. Many mice were beige or white, but Tandy offered a black mouse with an orange button for their TRS-80 Color Computer series.
Late '80s: A greater variety of IBM-compatible computers began to be sold with a serial port built-in, and Apple Macintosh systems were among the first to be sold with a mouse included. Most mice had either one or two buttons. Software was generally designed so that it could be used with or without a pointing device. A disadvantage of serial computer mice is that they must be unplugged when other serial accessories (ext. modem, digital camera, etc.) are utilized, on computers which have only one port of this type.
Early '90s: Some IBM-compatible computer systems were sold with mice included during the early 1990s, especially in the years after 1991. One-button mice had become relatively inexpensive, but the 1990 Radio Shack catalog still listed two-button units for $49.95, and a Logitech three-button mouse cost just under $100. Microsoft offered a bundled mouse and Windows 3.1 package, because of the significant advantage it provides in using Windows.
Mid '90s: More and more computers were being sold with mice, and one-button units were largely abandoned except for Macintosh systems. PS/2 mice started to become more common than serial port models, and many computers came with a 2nd PS/2 port specifically for the mouse. Windows 95 (and later versions) added a useful feature which enables keyboard-only users to control the mouse pointer and buttons with their numeric keypads.
Recent History
: Mice with scroll wheels and/or USB cables have become more widespread. A greater number of computers now have dark-colored exteriors, and mice with similar coloration have been provided to match them. In 1999, Apple dropped the use of ADB mouse/keyboard ports and replaced them with USB, according to wikipedia.org. It is not uncommon for new computers to be sold with a PS/2 scroll mouse included, and they have become rather inexpensive.

Overall, the history of computer mice has frequently involved different ports, more buttons, and a trend in favor of including them with new systems. It remains to be seen whether the mouse will continue to undergo such changes during the next ten or twenty years, or if it will stay much the same.
