The Launch of the Smartphone

For many years, telephony was dominated by fixed lines, then wireless handsets and now, finally, the cell phone. Many people who were used to using public pay phones saw the mobile phones as the revolution. It would be for about another decade or so that people would use the cell phone and still marvel at its ingenuity. The cell phone of yester years was a basic device, compared to the gadgets that are currently on the market. They allowed for making and receiving calls, texting, playing games and a host of other useful functions.

However, the advancement in technology was still progressing and so the smartphones were invented. This device is a superior model of the cellular device in very many aspects. For one, it is able to do all the functions that the cellular phone does, but has other unique and sophisticated functionalities those basic mobile phones cannot do. For instance, the smart devices are able to run applications such as word processors, have GPS tracking capabilities, use touchscreen technology for input and many other state-of-the-art functions that computers do. Smart devices come with a processor, RAM and wireless capabilities that the ordinary cellular phones does not have.

A popular version of the smart device has been invented, this is a gadget called the Tablet pc. A tablet is an advanced version of a smartphone, which uses touchscreen technology exclusively for input. Whereas some of the smart devices have a fully functioning QWERTY keyboard, tablets only have a touchscreen. The features of these devices are almost the same as those of smart devices and are sometimes considered to be one and the same thing. However, tablets are more advanced in the sense that they are designed primarily to be a bridge between a mobile phone and personal computer.

One feature that is becominincreasingly common as the cellular phone technology advances is the use of touch screen technology. This technology has enabled the rapid growth of the touch phone and other similar devices that use touch sensitive screen for input, instead of the conventional keypad. Touch screens were invented to replace the QWERTY keyboard, as it made more sense to have a virtual keyboard that disappears when not in use. This allows for the design of compact and robust gadgets which can have an extra large screen to power multimedia, as the gadgets do not need to use actual keyboards that eat up space.
