Working of Wireless Keyboard
Wireless communication can be defined as the transfer of data or information from one source to another without using any type of cords and wires. In this type of communication data or information is transferred over the air in the form of special waves commonly known as electromagnetic waves. These waves are the necessary part of electromagnetic spectrum that exists in the atmosphere. In the first step of this process data is encoded in special codes at the sender’s point, then they are allowed to travel over the air and then they are decoded back to their original form at the receiver’s point. This type of wireless communication is commonly used in most of the electronic devices available in the market at the present time. In today’s world people are widely using this mechanism of wireless devices in their daily lives like wireless remote controls, wireless keyboards and printers etc.
Nowadays computer has become one of the basic needs of every person. Computers are used almost everywhere like schools, colleges, hospitals, industries, shops, homes, airports etc. but the wires attached to that computer sometimes create big problems for the users of computer. New technologies are coming up day-by-day, which are reducing the use of wires or cords and providing more comfort to the users. Laptop is the most beneficial and easy to use wireless device for most of the people. You may have seen a lot of businessmen, employees and even students having laptops but peripherals attached to a normal desktop PC are also coming without wires like wireless web cam, wireless keyboard, wireless printers and wireless mouse etc. which are facilitating the use of these devices from a good distance from a desktop PC.
Nowadays there are a number of wireless keyboards available in the markets. These wireless keyboards are just like an ordinary keyboard except for one key difference. These wireless keyboards transfer data from the keyboard to the CPU using IR infrared rays or beams. When you hit a button on the keyboard a beam of information is send from the keyboard to a receiver that is already attached into the computer. With the help of this wireless technology you can place your wireless keyboard in a position that a normal keyboard may not reach. But the infrared keyboard receiver should be placed in a place where the infrared beam or rays can easily reach.
If in case the wireless keyboard is not pointed accurately in the direction of the receiver or if the path of beam is blocked then the data will not be transmitted to the computer. This is a big disadvantage with wireless keyboards and it can cause a serious problem for the users if the keyboard is not placed correctly or someone is walking between the keyboard and the receiver. This distance of the receiver and the wireless keyboard vary from brand to brand and model-to-model, so it is better to read the features of the keyboard before purchasing it.
