A personal digital assistant (PDA), also known as a handheld PC, or personal data assistant, is a mobile device that functions as a personal information manager.

The term evolved from Personal Desktop Assistant, a software term for an application that prompts or prods the user of a computer with suggestions or provides quick reference to contacts and other lists. PDAs were discontinued in early 2010s after the widespread adoption of highly capable, especially iOS and Android-based smartphones.

Nearly all PDAs have the ability to connect to the Internet.

A PDA has an electronic visual display, enabling it to include a web browser, all models also have audio capabilities enabling use as a portable media player, and also enabling most of them to be used as mobile phones.

Most PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless Wide Area Networks.

Most PDAs employ touchscreen technology.
