Personal digital / data assistant

Personal digital assistant (PDA; aka 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 [like handheld PCs] were largely discontinued in the early 2010s after the widespread adoption of highly capable, in particular iOS? and Android-based, smartphones?."
