A computer keyboard mouse is a device that allows computer users to point and click to access and open things like files, browsers, programs and websites. A typical mouse will consist of two buttons, a wheel and a cable. The cable is to be connected to the correct port so that the mouse will be able to be used. The left button is typically used for various things such as selecting and opening files, browsers, web pages and programs. The right button is used for various things such as copying text, deleting text and performing various tasks in certain word processing programs. The wheel is typically used to scroll up and down on web pages and it is sometimes used as a third button. A computer keyboard mouse is operated by a persons hand and most mice are designed for those who are right handed. Left handed mice can be purchased and some mice can be programmed to be used by the persons dominant hand.
A computer keyboard mouse comes in several different varieties. There are USB mice, port mice, laptop mice, ergonomic mice and wireless mice. The USB mouse is just a mouse that is plugged into a USB port either on a desk top or a lap top computer. A port mouse is a basic desk top mouse. A laptop mouse is typically built into the laptop, underneath the keyboard and uses a persons fingers instead of a ball. An ergonomic mouse is supposed to be good for supporting the wrist and hand. A wireless mouse is a mouse without a cable that is connected to a computer by a separate device that is typically plugged into a USB port. Wireless mice typically use infrared technology to work. All mice are made of plastic and they have a rubber ball on the bottom of them that allows them to move. A computer keyboard mouse can be purchased at office supply stores, electronic stores and most super stores (online and offline). Laptop mice are built into the laptop, but consumers can purchase separate mice that connect to a USB port if desired. Mice vary greatly in price depending on the type of mouse. Basic computer mice can cost anywhere from $5.00 to $50.00. More sophisticated mice can cost anywhere from $25.00 to over $100.00. Most computer mice will work with just about any computer, but some wireless mice will only work with computers with newer operating systems so it is important to read the system requirements before purchasing one. The computer keyboard mouse has been an essential part of the computer since its debut in 1972. They allow computer users to access things easily and have many different functions. If the mouse was never invented, computers would most likely be=2 0far less sophisticated.
