PDAs, or Personal Digital Assistants, were once a popular technology item for organizing personal and professional schedules. Today, this term is not as commonly used, but there are plenty of synonyms that describe similar devices. For example, smartphone or mobile phone is a common replacement for PDAs, as both have the ability to connect to the internet and manage schedules and contacts. Other synonyms include pocketPC, palmtop computer, and handheld computer. These devices have become smaller and more powerful over time, making them almost indispensable for modern life. Regardless of which term you use, these devices are incredibly useful for managing your busy life on the go.
