We explain what the mouse is and the main functions of this peripheral device. Also, as it is an optical and mechanical mouse.
What is themouse?
In computing, is calledmouse (from English: "mouse"), mouse, pointer or pointer to a peripheral device input, manual use, designed to facilitate user interaction with the graphical environment interfaces of many computer systems. Today it is a popular and traditional accessory of the computing.
The mouse works by capturing through various mechanisms the movement that he Username prints it by moving it with your hand, and translates it on the screen through the position of a cursor or pointer, usually in the form of an arrow or a hand.
To do this, it must transmit the signals of the movement detected to the computer, which can be done through a cable (PS / 2 or USB) or remotely, using various wireless devices (wireless).
The earliest versions of the mouse were made of wood and were designed in the 1960s by Douglas Engelbart and Bill English at the Standford Research Institute. Although today they would look rudimentary, their operation and design were basically the same, and although they were called “X and Y axis indicators for visual systems”, they were nicknamed “mouse” due to their resemblance to this little animal. Eventually the nickname would remain and the first contemporary mouse model was introduced in 1968.
In many systems this device has been replaced by the touch screen, which allows the user's own hand, or a special indicator bar, to enter the information movement directly to the system, without the need forhardware additional.
Mouse functions
The mouse has the task of reflecting the movements of our hand in the virtual graphic environment of the system, that is, of serving as an extension or representation of our will within the computer system.
Thus, we can dictate to the system which applications we want to run, by pressing the button (or one of them: the Macintosh mouse has a single button, while the IBM mouse has two) on the icon that represents it, or even where we would like to move it in the folder system, represented by windows that display their content.
Similarly, the mouse can serve as an interface with app software like video games, spreadsheets and much more.
Optical mouse
Optical mice are known as those that have a system for tracking the position of the device by means of an issuing entity of light (such as the Laser or the LED), instead of the usual rotating ball that is inside the mechanics. This allows you a displacement more fluid, accurate and less prone to dirt build-up. However, it requires higher energy consumption.
Mechanical mouse
This is the name of the classic mouse, whose operation requires a rubber ball or plastic inserted inside to move two wheels or fixed axles, whose movement is transmitted through electronic circuits to the computer.
This mechanism is the traditional and most economical, but it is much less precise than optical mice and has a tendency to accumulate dirt when moving on the surface, which leads to obstacles and other deficiencies in its operation.
