Wireless Communication

Wireless communication is among technology’s biggest contributions to mankind. Wireless communication involves the transmission of information over a distance without help of wires, cables or any other forms of electrical conductors.

 

The  transmitted distance can be anywhere between a few meters (for example, a television’s remote control) and thousands of kilometres (for example, radio communication).Some of the devices used for wireless communication are cordless telephones, mobiles, GPS units, wireless computer parts, and satellite television. The growth of wireless network has enabled us to use personal devices anywhere and anytime.

Microcontroller

A microcontroller is a small and low-cost computer built for the purpose of dealing with specific tasks, such as displaying information in a microwave LED or receiving information from a television’s remote control. Microcontrollers are mainly used in products that require a degree of control to be exerted by the user.

Microcontroller has an input device in order to get the input and an output device (such as LED or LCD Display) to exhibit the final process.  The architecture of a microcontroller depends on the application it is built for. For example, some designs include usage of more than one RAM, ROM and I/O functionality integrated into the package.
