What is PDA::?
The main purpose of a personal digital assistant (PDA) is to act as an electronic organizer or day planner that is portable, easy to use and capable of sharing information with your PC. It's supposed to be an extension of the PC, not a replacement.
PDAs, also called handhelds or palmtops, have definitely evolved over the years. Not only can they manage your personal information, such as contacts, appointments, and to-do lists, today's devices can also connect to the Internet, act as global positioning system (GPS) devices, and run multimedia software.

The Birth of the PDA::::


Predecessors of the modern PDA include the Psion Organiser and the Sharp Wizard. These early devices, which were intended to be portable computers, came out in the mid- to late 1980s. They included small keyboards for input, a small display, and basic features such as an alarm clock, calendar, telephone pad and calculator. Support for specialized software such as games and spreadsheets was also included. The Psion Organiser II, released in 1986, was especially popular and more than half a million were sold.

In 1993, Apple introduced the Newton MessagePad at a price of $700. It provided users with an electronic notepad, to-do list, calendar, telephone log and address file applications. Some of the Newton's innovations have become standard PDA features, including a pressure-sensitive display with stylus, handwriting recognition capabilities, an infrared port and an expansion slot. However, the Newton MessagePad was too big, expensive and complicated, and its handwriting recognition program was poor. Apple discontinued the Newton in 1998.

The original PalmPilot was introduced in March of 1996 by Palm Computing (owned by U.S. Robotics at the time). It cost less than $300, ran on its own Palm operating system, fit in a shirt pocket and synchronized with consumers' PCs. The PalmPilot ran for weeks on AAA batteries, was easy to use, and could store thousands of contacts, appointments and notes. Part of its small size was due to the lack of a keyboard. Users used a stylus and the Graffiti language to input data.

Not to be outdone, Microsoft had been working on various forms of portable computing, including PenWindows and tablet computers. In November 1996, Microsoft released Windows CE, its first operating system for mobile devices. A number of manufacturers, such as HP, Compaq and Casio, adopted it for what was dubbed the Handheld PC -- the first Windows-based competitor for the PalmPilot.

Answer 3

PDA's (Personal Digital Assistants) are handheld computers that originally were designed as personal organizers, and they do this really well. The basic features of any PDA are a date book, address book, task list , and memo pad. While these features are very helpful at keeping someone organized, the feature that clinched their utility for any busy person who uses a desktop computer is that of easy synchronization of information with the desktop. For example, I can easily work on my desktop, make a new appointment and cut some directions out of an e-mail someone sent me and paste it into a memo using my PDA's desktop software. The next time I put the PDA in the cradle and synchronize, that new information ends up on my PDA.

Answer 4

PDA = Personal Digital Assistant

All cellphone companies offer a variety of them.
Most popular/common PDAs are:
- Palm Pilot
- BlackBerry
- Treo

They are used like planners. You can plan stuff, make phone calls, organize calenders, and go on the internet. I like to think of them as "hand-held computers."

Most have a large screen, that's touch screen & a "wand" that looks like a pen, so you can write/tap the screen to make it do as you command.
