How the Personal Digital Assistant works

The Personal Digital Assistant (PDA) is also known as palmtop computer. It is a hand held device with the combination of fax, telephone, computing, networking features and internet. One can use the PDA Phones like a simple mobile phone, web browser, personal organizer and fax sender. Most PDAs are run by pen based accessories in place of keyboard in the case of a portable computer. This pen-like device called as stylus, which can be used instead of your thumb to scroll, write, type, play games, and otherwise. The stylus is sleek, sexy, and offers natural but sophisticated feel to PDA use.

So, this type of mobile has the ability of handwriting recognition. Handwriting Recognition is a technique by which the computer system recognizes the natural handwriting generated by the stylus’s pressure applied to the touch screen. It can recognize the symbols and characters written by the stylus. The system recognizes the writing wrote by using the stylus and turns it into actually digital text. A modern miracle of electrical engineering, really!

Different PDAs are available in the market with voice input facilities, also. These types of smart phones use the technologies of voice recognition to enhance ease of use. In such types of PDAs, the system recognizes the word spoken with advanced artificial intelligence centers in the operating system. The system takes the dictation to match it up to a computerized bank of dictations in order to produce text to match the speech. So does it process natural language in one-of-a-kind text-to-speech integration.

Apple was the first company to introduce the PDA. In 1993, Apple computer introduced the PDA named Newton Message Pad. Shortly thereafter, many manufacturers made similar products. Today most popular PDA brand is manufactured by Palm, Inc.

Nowadays PDAs are a very attractive product among mobile device customers. Unlike a simple computer, it is with you all the time (as it is the hand held device) and designed to fit in your pocket, but is just like a powerful computer with a strong processor and a large memory capacity of up to 128 MB. The PDA has all the functionalities which a simple phone has but apart from that, such types of smartphones also have some more advanced features. For example, it is capable of connecting with and communicating to other electronic devices like digital cameras or personal computers. So, by using PDAs we can manage a large amount of data by connecting it with the other devices, as opposed to the integration-limited simple cellular phone.
