What is the function of PDA?

Pocket PC is an intelligent terminal device, small enough to be carried around in your pocket. It has its own operating system, allowing users to select and install various applications.

There are mainly three popular operating systems for PDA.

OS once occupied the largest market share, and Microsoft's PPC ranked second, and some manufacturers adopted Linux system.

With the development of smart phones, now, the stand-alone PDA has completely withdrawn from the market. Smart phone can be regarded as a follow-up product to replace PDA.

The most basic application of PDA is personal information management, such as schedule, notes, address book and so on. , but users can also install all kinds of software to expand their functions. Palm operating system has tens of thousands of applications, PPC has thousands of applications.

The smartphone I am using now uses the Palm operating system. In addition to its telephone and SMS functions, I use it to manage my schedule, keep accounts, take notes, record encrypted secret diaries, read novels, locate my mobile phone by GPS, carry a password book with me, install more than ten large dictionaries in Chinese and English, consult office documents, process information with a simple database, surf the Internet, listen to songs and watch movies, and install some gadgets. I also installed a few small games to play occasionally.

An important feature of PDA is that it can synchronize with PC. The input efficiency of PDA is slightly lower than that of computer, and its processing ability is also weak. Therefore, complex data are processed on PC and then synchronized to PDA, which can be consulted with you at any time.

Pocket PC has a small screen, slow input and low processing power, so it can't completely replace PC. But it is a good extension of the computer, which allows some functions of the computer to be put in your pocket and carried around at all times.
