What does a Personal Digital Assistant (PDA) primarily achieve?

A Personal Digital Assistant (PDA) is specifically designed to manage personal information in a compact, handheld format. This type of device typically includes features such as a calendar, address book, task manager, and note-taking capabilities, allowing users to organize their daily activities and access important information easily.

The core functionality of a PDA focuses on making personal management more efficient and accessible. Unlike desktop computers or servers, which may run large-scale applications or connect multiple workstations, PDAs are intended for individual use, prioritizing portability and convenience. While they can perform simple calculations, their primary role is not as a calculator but as a tool for organizing and managing personal data. This makes the selection of managing personal information the most appropriate answer when considering the main purpose of a PDA.
