Every one of us is familiar with what a radio is. Our grandparents have heard the news and music through the local radio broadcasting channel from a huge radio receiver box. We have now moved on to CD players and internet cloud music and iPods. Wireless networks have changed the way we store data, listen and watch audio and video and communicate with the rest of the world. You will be surprised to know that the word ‘radio' and ‘wireless' is synonymous and are largely the same technology. In fact, there is proof that radio was initially referred to as ‘wireless telegraphy' which was shortened to wireless. This article will shed more light to beginners on the basic difference (if there is one) between both these words.
