What is a PDA (Personal Digital Assistant)?

A personal digital assistant (PDA) is a handheld device designed to facilitate organizational ability from a mobile platform. While the original PDAs were somewhat limited to keeping address, phone, calendar, and task lists, today’s PDA can function as a cellular phone, fax, provide Internet connectivity, and much more. There are many different types of PDAs, but most models work with either Palmtop software or a special version of Microsoft Windows called Windows Mobile. All models can interface with a laptop or desktop system, though optional accessories may be required. Synchronization between computer and PDA is one of the most popular features of this digital device.

Some PDAs work only with a stylus, while others incorporate a miniature keyboard. A PDA might include handwriting recognition software, voice recognition, and a digital voice recorder. Some models come with a suite of software programs preinstalled, while others offer optional programs if desired.

A PDA might also incorporate cellular phone functionality and wireless local area network (LAN) capability. Connect to the Internet to check email, send messages, or watch the stock market. With flash card capability, a PDA can store, access, and transfer virtually any kind of data, including maps, spreadsheets, presentations, and dockets. 

A PDA can even function like a mini-computer to make those last minute changes while en-route to the office or to a client. Windows Mobile runs a variety of mobile applications, including Excel and Microsoft Word. If you have a few minutes, use your PDA to kick back and listen to your favorite music, watch videos, or play games.

PDAs range in price from about 100 US Dollars (USD) to 500 USD or more. In general, the more expensive the PDA, the more features it incorporates. Some models have permanent rechargeable batteries, while others use replaceable batteries. Display type and size also play into price.

If in the market for a PDA, it is best to consider many models before choosing. Specific features that push up the price tag may not be required for your particular needs. Important considerations are ease of use and screen resolution, size, and brightness. In terms of functionality, look for a model that will serve your needs without incorporating too many unnecessary features.

A PDA can be an extremely useful tool, replacing the cell phone while adding the functionality of an organizer, planner, and mini-computer node. It is highly likely that once you use a PDA, you’ll wonder how you ever got along without one.
