PalmOS is the operating system for Palmtops and PDAs that runs on Palm products and under license on other handhelds. PalmOS, which has been available in various versions since its introduction in 1996, supports organizer functions and communication services.
Basic organizer functions include address management, scheduler, calendar, notebook, spreadsheet, and a simple word processor. These functionalities were adapted to the application and device-specific requirements in the various PalmOS versions and the ease of use was improved by additional functions. These included spreadsheet and presentation programs, support for color displays, and character recognition of handwritten notes.
The communication technology was first supported with an infrared interface, later radio modem, Bluetooth and WLAN connections according to 802.11b were added. This allows the user to use PDAs with PalmOS in mobile computing with direct access to corporate resources.
PalmOS functions were extended in later versions to include an HTML and WAP browser and an e-mail client. Higher resolution display, memory cards with flash memory, cell phone functions, data backup, built-in camera and multitasking are further development stages of PalmOS of versions 5 and 5.4. The variety of software applications is reflected in more than 20,000 programs for all imaginable industries. For science as well as for entertainment, for humanities, production, human resources and many other areas.
PalmOS was sold to the company Access and renamed by them to Garnet OS. The Palm company developed webOS as PalmOS successor, which supports Internet services more strongly. The successor operating system to Garnet OS is Nova OS.
