OPTICAL MOUSE Meaning and
Definition
-
Optical Mouse - A type of computer mouse that uses optical technology to track and detect movement. It operates by emitting a beam of light, usually a red LED (light-emitting diode), onto the surface below it, and uses a small camera to capture images of the surface at a rapid rate.
The images captured by the camera are analyzed by the mouse's internal processor, which determines the mouse's position and movement. Unlike traditional mechanical mice that use a rubber ball and rollers, optical mice do not have any moving parts that can be affected by dirt or dust. This makes them more accurate, reliable, and less prone to mechanical failures.
Optical mice offer improved sensitivity and precision, allowing for smoother and more responsive movement compared to their mechanical counterparts. They can work on a variety of surfaces including desks, mouse pads, and even on irregular or reflective surfaces.
Most optical mice have two buttons along with a scroll wheel placed between them, which can be used for scrolling through documents or websites. Many also feature additional buttons on the side or top that can be programmed for specific functions, such as launching applications or executing shortcuts.
Overall, optical mice have become the standard input device for modern computer systems due to their efficiency, convenience, and ease of use.

Etymology of OPTICAL MOUSE
The etymology of the term "optical mouse" can be broken down as follows:
1. Optical: This word derives from the Greek word "optikos", meaning "of sight" or "of the eye". It is related to the Greek word "opsis", which means "sight" or "vision". In modern usage, "optical" refers to the branch of physics that deals with light and vision.
2. Mouse: In the context of computer technology, a "mouse" is a device used to control the movement of a cursor on a computer screen. The term "mouse" was coined by Douglas Engelbart, one of the inventors of the computer mouse, and it was inspired by its physical resemblance to a rodent.
Hence, "optical mouse" refers to a computer mouse that uses optical technology (typically a light-emitting diode and a sensor) to track and detect its movement.
