1. What is PDA? PDA (or Personal Digital Assistant) is a tiny computer which can be held in one hand. The term PDA refers to a wide variety of handheld devices, palmtops and pocket PCs.
2. Some history. The first PDA was released in 1986 by Psion. Followed by Psion's Series 3, in 1991, which began to resemble the more familiar PDA style. The term PDA was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas. Today, almost all PDAs are smartphones. Over 150 million smartphones are sold each year, while "stand-alone" PDAs without phone functionality sell only about 3 million units per year.
3. Special features. For input, you type at a small keyboard or use a stylus - a special pen used with a touch screen to select items, draw pictures, etc. Some models incorporate handwriting recognition, which enables a PDA to recognize characters written by hand. Some PDAs recognize spoken words by using voice recognition software.
3. Special features. Handhelds can also function as mobile phone and GPS receivers. Another very useful feature of handhelds is that they are able to synchronize data with other computers.
3. Special features. A basic handheld usually includes a clock, date book, address book, task list, memo pad, and calculator and is very useful for everyday tasks. These computers can be used to access the Internet via WI-FI or Bluetooth technology, to send and receive e-mails, to store and listen MP 3 audio files, to store data.
4. Users. Individual users, who often need access to Internet and store information.
