This page provides useful information about mobile technology in general. The mobile phone has evolved from a voice apparatus to a multi-functional device that offers increasingly sophisticated applications. No other device has come close to the sophistication, the versatility and the power of the mobile phone.
Convergent technologies have now combined the mobile phone and various services – web, email, mobile TV, FM radio, card reader, camera, mobile computer, e-books, music player, voice recorder, flash drive, games, and GPS navigation, among others.
Actually, there’s no point calling it “phone” any longer. Perhaps just “mobile” will do.
Smartphones, Phablets and Tablets
A smartphone is a mobile device with voice and data capabilities and which runs an operating system that allows the installation and running of third party native applications. Smartphones have displays of 5 inches and less.
Some of the currently available smartphone operating systems are:
- Android OS
- BlackBerry OS
- Firefox OS
- Windows Phone OS
A phablet is a large smartphone with a display of between 5 and 7 inches in size. It is a hybrid between a phone and a tablet. Phablets run same operating systems that smartphones run.
A tablet is a new type of internet-enabled computer that works in a similar way to a smartphone, having a touchscreen display and downloadable apps, smaller than a laptop and bigger than a smartphone or phablet. Displays range between 7 and 14 inches. Most tablets run same operating systems that smartphones and phablets run, but some others run full desktop operating systems.
