hello rani fibre optics is A technology that uses glass or plastic threads fibers to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves. Fiber optics has several advantages over traditional metal communications lines: Fiber optic cables have a much greater bandwidth than metal cables. This means

well , Optical zoom uses the optics lens of the camera to bring the subject closer. Digital zoom is an invention of digital video cameras. It is not uncommon to see digital videocams with 300x digital zoom.Optical zoom is equivalent to you physically moving closer to the subject although your lens does the moving not you so you capture the actual image without any kind of digital manipulating

well, An optical mouse is a computer mouse which uses digital image processing technology to track the position of your cursor on the screen. In fact, an optical mouse includes a tiny camera that is able to take an astonishing 1,500 pictures per second. Optical mice are also quite beneficial in that they are easy to maintain and have no moving parts that are prone to failure.The goal of both laser

Optical mice are the de facto standard for mice to communicate between the end user and the computer. The optical mouse is a great improvement over the mechanical mouse that was created in the early 1970s.The Optical mouse was introduced in 1999 by Agilent Technologies; the technology uses a tiny camera that takes thousands of pictures per second to determine position and speed.The optical mouse

The Zoom telephoto function can either be digital or optical. Both allow you to get a closer view of your image before you take your picture. Though cameras do use both types of zoom, it is preferable to have a higher optical zoom to increase the quality of the image. Digital zoom will definitely also do the job right, but more often will enhance the magnification the optical zoom has already

A Optical mouse uses light to detect movement. It emits a light and senses its reflection as it is moved. Early optical mice required a special mouse pad, but todays devices can be rolled over 1999, the optical mouse actually uses a tiny camera to take 1,500 pictures every second. Able to work on almost any surface, the mouse has a small, red light-emitting diode LED that bounces light off

Hi Friend,The Three types of computer mouse are1.Mechanical2.optomecha nical3.optical...well, Three Basic Types Of Computer Mouse are :Mechanical:This type of computer mouse has a rubber or metal ball direction. A mouse pad should be used under the mouse to run on.Optomechanical: This type is the same as the mechanical mouse except that it uses optical sensors to the motion of the ball. A mouse pad should

Fiber optics optical fibers are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances.If you look closely at a single optical fiber, you will see that it has the following parts: Core - Thin glass center of the fiber where the light travels Cladding - Outer optical material

these are the special type of amplifier meant for use in optical transmission as they can directly amplify the light signal without need of change into electrical...An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from

Optical data storage refers to storage systems that use light for recording and retrieval of information. Optical recording was for a long time, and is still, considered a future replacement for magnetic recording. Optical recording systems potentially have much greater reliability than magnetic recording systems since there is a much larger distance between the read/write element and the moving
