What is Mouse ? A personal computer that was purchased in the early 1980s probably included a keyboard as the only input device. Today, every PC includes a pointing device as standard equipment. Full-size PCs usually include a mouse as the pointing device. A mouse is an input device that you can move around on a flat surface (usually on a desk or keyboard tray) and controls the pointer. The pointer (also called the mouse pointer) is an on-screen object, usually, an arrow that is used to select text; access menus; and interact which programs, files, or data that appear on the screen. The mechanical is the most common type of pointing device. A mechanical mouse contains a small rubber ball that protrudes through a hole in the bottom of the mouse’s case. The ball rolls inside the case when you move the mouse around on a flat Rollers surface. What is Mouse ? We know that mouse sends various signals to the computer because it consists of rollers and sensors which is very helpful by telling the computer direction and speed, and hence the computer pick this signal and the cursor moves on the screen. Another kind of mouse which is non –mechanical may be called an optical mouse. This kind of mouse releases a ray of light from its underside; it uses the light’s reflection to judge the distance, direction, and speed of its travel.
BENEFIT OF MOUSE
Basically, what is mouse . The mouse offers two main benefits.
First, the mouse lets you position the cursor
anywhere on the keys screen. You quickly simply move the using pointer the cur-to the on-screen position you want and press the mouse button; the cursor appears at that location.
Second, instead of forcing you to type or issue commands from the keyboard, the mouse and mouse based operating systems let you choose commands from easy-to-use menus and dialogue boxes. The result is a much more intuitive way to use computers. Instead of remembering obscure command names, users can figure out rather easily where commands and options are located. If you use a drawing program, you can use the mouse to create graphics such as lines, curves, and freehand shapes on the screen. The mouse has helped establish the computer as a versatile tool for graphic designers, starting what has since become a revolution in the graphic design field.
USING THE MOUSE
you use a mouse to move the pointer to a location on the screen, a process called pointing. Everything you do with a mouse is accomplished by combining pointing with these techniques:
Pointing means pushing the mouse across your desk. On the screen, the Pointer moves in relation to the mouse. Push the mouse forward, the pointer moves up, push the mouse to the left and the pointer moves to the left. To point to an object or location on the screen, you simply use the mouse t place the pointer on top of the object or location.
The mice that come with an IBM-compatible computer usually have two buttons clicking—or single-clicking but dragging are usually carried out with the left mouse buttons. Double-clicking is primarily used with desktop objects such as icons. For example, you can double-click program’s icon to launch the program. As we know that generally moving of items from one place to another with the help of positioning of the mouse pointer is called Dragging. The action by picking the item from one position to another is “Dragged”. Dragging is a very handy tool. In a word-processing program, for example, you can drag text from one location to another in a document. In a file-management program, you can “click click” a document’s icon and drop it onto a printer’s icon to drag print the document. Windows and many Windows programs support right-clicking, which means pointing to an item on the screen, then pressing and releasing the right mouse button. Right-clicking usually opens a shortcut menu that contains commands and options that pertain to the item to which you are pointing.
MOUSE BUTTON CONFIGURATIONS
The mouse usually sits to the right of the keyboard (for right-handed people), and the user menu uses the mouse with the right hand, pressing the left button with the right forefinger. For this reason, the left mouse button is sometimes called the primary mouse button. If you are left-handed, you can configure the right mouse button as the primary button. This configuration lets you place the mouse to tie left of the keyboard, control the mouse with your left hand, and use your left forefinger for most mouse actions. Newer mice enable you to configure buttons to perform different tasks than clicking. You might configure a button to delete selected text, for example, or to open a program that lets you search for files. Such settings may limit the usefulness of the mouse but can be helpful if you need to perform a certain task many times.
