Hand-Held Systems in Operating System:
Definition and Explanation:
Hand-held systems include a personal digital assistant or PDA. It is a remarkable, tiny, fully functional computer that can be held in one hand. PDA can hold downloaded email and play music.
The small computer organizers were available in 1980s. The idea of making hand-held computer for storing addresses and phone numbers, taking notes and keeping track of daily appointments originated in 1990s. One of the first PDAs that was commercially available was Apple Computer's Newton Message Pad. It was too big, expensive and complicated. Its handwriting recognition program was poor.
In 1996, the original Palm Pilot was introduced and was a hit with consumers. It was small and light enough to fit in a shirt pocket. PDA was originally intended to be simple digital calendars. It has evolved into machines for playing games or music and downloading information from the Internet. It complements a desktop or laptop computer.
