PDAs are generally not equipped with keyboards, and use handwritten input or voice input. the main operating systems used by PDAs are Palm OS, Windows CE, and EPOC.
Palm OS is a 32-bit embedded operating system for handheld computers. This system was developed by the Palm Computing division of 3Com. (Palm Computing is now a separate company.) The combination of Palm OS and the synchronization software HotSync allows the synchronization of information on the Pocket PC and the PC, extending the functionality of the desktop to the palm of the hand.
At present, Palm OS-based PDAs are mainly 3Com's series of products, such as Palm IIIx, Palm V, Palm VII, and the IBM WorkPad c3, which also uses Palm OS. Sony and other companies have also obtained a license from Palm Computing to develop Palm OS-based PDAs. The battle between Palm OS and Windows CE is unfolding.

Windows CE is an embedded operating system developed by Microsoft for use in handheld devices and information appliances. The system can be seen as a simplified version of Windows 95, and as such is very similar to the latter, especially in terms of its GUI (Graphical User Interface). This makes it easy for users familiar with Windows 95 to get to grips with Windows CE.
Compared to its competitor, Palm OS, Windows CE is more powerful, especially in multimedia. The downside is that it is quite bloated, requires a lot of hardware, and consumes a lot of resources, such as power. In addition to Microsoft Handheld PCs, there are also handheld devices from Casio, Hewlett-Packard, NEC, and Samsung that use Windows CE.

EPOC is an operating system from Psion Software that specializes in mobile computing devices, including Pocket PCs. Earlier releases of EPOC16 were 16-bit operating systems that have been embedded in many handheld devices for many years. The new EPOC32 is 32-bit and supports multitasking.
In the PDA market, EPOC is a strong competitor to Windows CE and Palm OS. Currently, EPOC is supported by Ericsson, Motorola, Nokia, Panasonic, and Psion PLC, which ****together formed Symbian, a company dedicated to EPOC development.
The beginnings of PDAs can be traced back to Apple's Newton Message Pad, introduced in 1993, and similar products were introduced by manufacturers shortly thereafter. At present, the price of PDA is still high, but experts believe that it will eventually come into the "common people's homes" and become a real "personal digital assistant".
The above is a broad definition of a PDA, and at the moment, there is a narrower understanding of PDAs.
Narrowly defined PDA refers to what can be called an electronic organizer, which has a single function, mainly to manage personal information, such as address book, notes and memos, scheduling, notes, calculator, audio recording, and thesaurus and other functions. And these functions are cured, can not add new features according to the user's requirements.
Broadly speaking, PDA refers mainly to palmtop computers, but of course also includes other small digital devices with similar functions. The term PDA also has different interpretations. PDA in the narrow sense does not have a keyboard, using handwriting input, voice input or soft keyboard input. The broader definition of PDAs includes both keyboard-less and keyboarded ones. However, in the Chinese market, almost all PDAs do not come with a keyboard.
Both PDAs and Pocket PCs of interest to the PDA era are broadly defined. Of course, the information we provide comes from different sources, so each article may have a different understanding, definition, or usage of the terms used. In addition, more and more people are understanding the term PDA in a broader sense, both domestically and internationally on the major PDA websites.

Digital Digital Assistant is an acronym that literally means "personal digital assistant". This handheld device combines computing, telephony, faxing, and networking functions. It can not only be used to manage personal information (such as contacts, plans, etc.), but more importantly, can browse the Internet, send and receive Email, can send faxes, and can even be used as a cell phone. What's more, all these functions can be realized wirelessly. Of course, not any PDA has all of the above features; even with, but also due to the lack of appropriate services and can not be realized. However, it can be predicted that the trend of PDA development is the trend of computing, communications, networking, storage, entertainment, e-commerce and other multi-functional integration.
