computer mouse
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 mice are cordless, relying on short-range radio communication with the connected system. Mice originally used a ball rolling on a surface to detect motion, but modern mice often have optical sensors that have no moving parts. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as selection of a menu item on a display. Mice often also feature other elements, such as touch surfaces and "wheels", which enable additional control and dimensional input.A computer mouse is a handheld hardware input device that controls a cursor in a GUI (graphical user interface) and can move and select text, icons, files, and folders on your computer.
For desktop computers, the mouse is placed on a flat surface such as a mouse pad or a desk in front of your computer. The picture is an example of a desktop computer mouse with two buttons and a wheel.Who invented the mouse?
The mouse was originally known as the X-Y Position Indicator for a Display System and was invented by Douglas Engelbart in 1963 while working at Xerox PARC. But, due to Alto's lack of success, the first widely used application of the mouse was with the Apple Lisa computer. Today, this pointing device is on virtually every computer.
What are the uses of a mouse?
Below is a list of computer mouse functions to give you an idea of all the things a mouse is capable of doing.
Move the mouse cursor - The primary function is to move the mouse pointer on the screen.
Open or execute a program - Once you've moved the pointer to an icon, folder, or other object clicking or double clicking that object opens the document or executes the program.
Select - A mouse also allows you to select text or a file or highlight and select multiple files at once.
Drag-and-drop - Once something is selected, it can also be moved using the drag-and-drop method.
Hover - Moving the mouse cursor over objects with hover information can help discover the function of each object on the screen. For example, hover the mouse over the "hover" link to see an example.
Scroll - When working with a long document, or viewing a long web page, you may need to scroll up or down. To scroll, use the mouse wheel, or click and drag the scroll bar.
Perform other functions - Many desktop mice also have buttons that can be programmed to perform any function. For example, many mice have two side buttons on the thumb portion of the mouse the button closest to the palm can be programmed to go back on web pages.
