How Wireless Keyboard Mouse & Headphone Works?

In these days you all knows, there is revolution in technology sector everywhere in the world. There is also improvement in IT sector. Computer technologies changed in to latest technology, you all people use who already use computer (PC) they know wired Keyboard, Mouse, Headphone and mice. They all observed difficulty using these wired but before few year there is no option to replace this problem but now technology improved and we have wireless technology to replace old technology. Scientists and engineers together made Wireless, Keyboard, Mouse and Headphone. These products are easily available in local market in cheap price.

What's Wireless Keyboard Mouse & Headphone?

These are computer hardware component already available in market easily but old component are wired, this is new wireless technology. It is also available now in market. They allow computers/laptops or tablets to interact with the human using different medium (Example Bluetooth, infrared, laser technology etc...).
Wireless keyboard is very popular in these days because a lot of other feature also attached in wireless keyboard. Some keyboards are like laptop panel in which include mouse moving button and laptop mouse panel too. And some has included also thumb impression panel.
Headphone is used normally for listening music, communication using mice from one place to other but in old days it is only wired headphone but now wireless headphone is the latest technology in these days, in many counties didn't have this technology very common until now but with the passage of time wireless component will improve their rating in every country like old technology.

How they Work's?

Wireless Keyboard, Wireless mouse, Wireless headphone are usually working on same technique medium there are different medium used by different companies example Bluetooth, infrared, radio frequency (RF), optical, laser, LED & sensors etc... In these days two types of instrument available in market optical and laser.

In optical keyboard LED and sensor embedded, LED use concept of "electro luminescence" & photoelectric sensor catch emitting light rays from other device. When user press any key every key have unique light ray’s angle & type so sensor detect what user want.
In laser keyboard use metal-oxide semiconductor (CMOS), image of keyboard keys projected on straight surface and CMOS monitored moving finger on virtual Interface using infrared sensor.

In mouse two major components are required transmitter & receiver just like keyboards but in optical mouse LED lights & sensor work together. Red light produced by LED captured by CMOS & track movement using Digital Signal Processor (DSP), they send data to computer and computer follow instruction. In which also use Dots per Inch (DPI) technology to produce refine movement on pixel, normally optical mouse use 400 to 800 DPI.
In laser mouse working like optical mouse but little technology improved in laser mouse minimum DPI used by laser mouse is 2000 DPI it is much better than optical mouse. They use invisible laser rays for detect the movements & transferring data to its destination.

Wireless headphone normally work with Bluetooth technology, receiver and transmitter communicate both source and destination, it is also used with mobiles and TV's, there is a lot of people who have difficulty to during connection with mobiles TV's and computer but it is latest technology it is easy to use as compare to wired headphone.
Keyboard, Mouse & Headphone are major component for giving input to ant computer. If you want to buy any component of computer, you should buy best Keyboard/Mouse or Headphone. They are easily available in your near market and Enjoy....
