A Personal Digital Assistant (PDA) is a handheld device, originally designed as a personal organizer, but which has become much more versatile over the years. PDAs can can be used as a clock, calendar, address book, or spreadsheet, or for calculating, playing computer games, accessing the Internet, sending and receiving E-mails, taking pictures or videos, or recording notes. Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (PDA Phone), web browsers, or media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs).
