PDA or personal digital assistance has been a boon for the busy professionals and the tech savvy users. The device is a hand held computer that is enabled with some advance features to effectively manage contacts, tasks and appointments. This includes specific information like address database, calendar, to-do list and note taker.
PDAs are also wireless at times. A wireless PDA can offer features like e-mail, Web browsing and cellular phone service. For synchronisation of data between PDAs and desktop computer, cabled connection is needed, or it may happen through a wireless connection.
PDAs first came into existence in 1993, with Apple’s MessagePad. It was commonly known as “Newtonâ€. However, Palm Pilots improved upon the technology and made the device popular after couple of years. And with Blackberry’s synchronized e-mail in 1999, the PDA escalated to becoming a mobile office.
PDAs are extremely useful for storing heavy information. PDAs can be operated in two ways – PDAs may use a pen or keys. In the pen-based PDAs, the users operate the device using a stylus. Stylus is a thin pencil shaped device, the users select the menu on the screen by gently tapping with the stylus. This also means that most PDAs have a feature called handwriting recognition. Lightweight, full-size, folding keyboards can be connected and used when a desk surface is available.
Key-based units have tiny physical keyboards and various cursor keys and scroll wheels. Blackberry’s Thumbwheel is an example of such a device.
There are a vast number of PDAs available in the market today. Some have basic functionalities while others are enabled with many hi-end features. There are some PDAs which can even recognize voice. Thus, A typical PDA can function as a cellular phone, fax sender, Web browser and personal organizer.
PDAs are also called hand held computers, palmtops, and pocket computers.
