What is PDA?

A personal digital assistant (PDA), also known as a handheld PC,[1][2] is a variety mobile device which functions as a personal information manager. PDAs were largely discontinued in the early 2010s after the widespread adoption of highly capable smartphones, in particular those based on iOS and Android.[3]

Nearly all PDAs have the ability to connect to the Internet. A PDA has an electronic visual display, letting it include a web browser. Most models also have audio capabilities, allowing usage as a portable media player, and also enabling most of them to be used as telephones. Most PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless Wide Area Networks. Sometimes, instead of buttons, PDAs employ touchscreen technology. The technology industry has recently recycled the term personal digital assistance. The term is more commonly used for software that identifies a user's voice to reply to the queries.
