PDAs: Palm‐size computing power Available to Purchase

PDAs — Personal Digital Assistants — are pocket‐size computing devices that are capable of performing tasks similar to those of personal computers. The basic strength of PDAs is that they are conveniently portable. This strength is enhanced by adding communication capabilities to these devices. Most PDAs are capable of transferring files to personal computers over cable connections, or via infrared links, or both. Some PDAs are able to communicate over telephone lines, using built‐in or plugged‐in modems. A few are able to operate over radio‐frequency wireless links in much the same way as paging devices.
