A mobile phone is a communication device, often also called as “cell phone”. It is a device mainly used for voice communication. However, technological developments in the field of communication have made the mobile phones smart enough to be able to make video calls, surf the internet, play games, take high resolution pictures and even control other relevant gadgets. Because of this mobile phones today are also called “Smart Phones”.
World’s first ever mobile phone was demonstrated way back in 1973, by the Motorola’s then President and COO, John Francis Mitchell and an American Engineer, Martin Cooper. That mobile phone weighed around 2 kilograms.
Since then mobile phones have evolved in technology and shapes. They have become smaller, slimmer and more useful. Today mobile phones are available in various shapes and sizes, having different technical specifications and are used for a number of purposes like – voice communication, video chatting, text messaging, multimedia messaging, internet browsing, e mail, video games and photography. They also have short range wireless communication like Bluetooth and infrared. Phones having wide range of advance functions and large computing abilities are called smart phones. They have an edge over other conventional mobile phones, which are used only for voice communication.
