A computer mouse is an input device that is most often used
with a personal computer. Moving a mouse along a flat surface can move the
on-screen cursor to different items on the screen. Items can be moved or
selected by pressing the mouse buttons (called clicking). It is called a
computer mouse because of the wire that connects the mouse to the computer. The
people who designed the first computer mice thought that it looked like the
tail on a mouse. Today, many computer mice use wireless technology and have no
wire. On most computers, the user can move the mouse to move the cursor in the
same direction. To choose something that is on the screen, the user can move
the cursor to it and "click" the left mouse button. The right mouse
button is used to open menus that are different depending on where the cursor
is. The other mouse buttons can do different things, depending on the software.
Most mice have two buttons to click. Most mice also have a "scroll
wheel"—a small wheel found between the two main mouse buttons. The user
can move the wheel back and forth to "scroll" through things like a
website or folder. "Scrolling" means moving the words or pictures up
or down on the screen, so another part of the page comes into view. The wheel
can also be pressed, to click it like another button.
A computer mouse is an input device for a computer that provides information onto the x and y coordinates of the icon being moved around by this mouse (referred to as a cursor) based off of the hand movements of the user moving the mouse. Mouses also have three other button inputs. These are the left, right, and middle mouse buttons. The left button is typically used as the primary button, and is used to select, drag, open, and similar function. The right mouse button is usually intended for opening menus for additional options to be performed by the program being right-clicked on. The middle mouse button is actually a wheel that is used to move pages that extend beyond the boundaries of your screen up and down for easier viewing. Hope that helped! =)
