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.
Whatever you call it in your neck of the woods – mobile phone, cell phone, cellphone, handset, handy phone, or any other variation of these, this gadget has changed how the world lives, works, and plays. 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.
Smartphones, Phablets, and Tablets
A smartphone is a mobile or cellular device with voice and data capabilities, and which runs an operating system that allows the installation and running of third party native applications. In the past, many smartphones had a physical QWERTY keyboard, but over time, most are fitted with touchscreens for viewing of information, as well as data entry through an on-screen keyboard.
Some well-known smartphone operating systems (including those that are now history) are:
- Android OS
- BlackBerry OS
- Firefox OS
- Symbian OS
- Windows Phone OS
- Windows 10 Mobile
- Palm OS
The initial definition of a phablet is a large smartphone with a display of between 5 and 7 inches in size. It was a hybrid between a phone and a tablet. Phablets run the same operating systems that smartphones run. However, as mobile phone makers embraced big screen sizes, the name has died off. Most smartphones in existence today have big screens between 6 and 7 inches. The phablet is dead. Long live the smartphone.
A tablet is a new type of internet-enabled computer that works similarly 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 the same operating systems that smartphones run, but some others run full desktop operating systems.
