We often say that PDA, then what is the PDA, what the meaning of words, which of these categories, this last necessary to understand before you buy a PDA, and it is the first step before the purchase of PDA.
Term analysis PDA

Of course, as technology advances, some new features such as digital recording, etc. were added into the room. now is very vague definition of PDA, all the products are used in this collectively through the streets, and even referred to as many people put the PDA Pocket PC.
PDA classification
PDA In fact, should be broken down into electronic dictionaries, PDAs, handheld computer equipment and personal communications assistant, four major categories. the latter two because of technical and market development, has slowly fused together.
in electronic dictionary All the PDA products, this is a simple. Its main function is to provide a translation in English, phone number storage, the English word reading and other functions, it is characterized by all of its procedures are fixed in memory , and thus storage capacity is limited, and does not have a single function is also more scalable. but these products also has its unparalleled advantages. as they targeted are relatively strong, provides the necessary functions, such as games, computing, notebook and so on. In addition It also has small size, simple operation. Such representatives Electronic Dictionary Instant-Dict, celebrities, Wenquxing and so on. Of course, some new electronic dictionary also provides a communication function. through the additional connection kit and computers and you can exchange data between similar products. And also some electronic notebook market, will focus on such notes and daily business management. These products are often relatively large storage capacity, but its essence is, and electronic dictionary as the procedures are solidified in the storage chip, the same does not have expansion capabilities. typical of these products is that we are familiar with GUIDEC.
Pocket PC
Typically, the digital world will be such Pocket PC will be known as the PDA, the PDA is also representative of the true meaning. because it almost all the features of a typical home computer. The greatest feature of handheld computers is that they have their own operating system, usually fixed in ROM, The. The use of multiple storage devices are more expensive IC flash memory capacity is generally around 16MB. Pocket PCs generally do not have the keyboard, the use of handwriting and soft keyboard input, equipped with a standard serial port, infrared, and built-in access mode MODEM, so that personal computers and Internet connections. handheld computers and products in front of the biggest difference is its ability to extend the application. based on their operating system, anyone can use the programming language to develop the corresponding applications. You can also on your Pocket PC in any installation and uninstallation. because of its functionality is very comprehensive, it is also more complicated in operation, not for the primary computer users do not understand.
part in the Pocket PC, but also by different operating systems, Palm and PocketPC.Palm into the system using Palm OS, developed by the Palm; and PocketPC with WinCE series of systems developed by Microsoft. because of the difference between the body and system performance, these two still have a considerable body difference.
handheld handheld computer equipment computer equipment
the English name is HPC, meaning that Hand held PC. This is a range between laptops and Pocket PC products. Why do I say? because It has a common operating system, Pocket PC, but with a small keyboard. and its appearance is similar to a traditional laptop. its functions to the powerful than the Pocket PC, but the same size and weight should be increased, So in portable performance was worse than the Pocket PC.
personal communications assistant, personal communication assistant, in so many products is a most fashionable look. It's concept is to some of the effectiveness of handheld computers and mobile phones, pagers combination generated. this product is its most important feature of abandoned the general use of telephone lines and wireless data reception means, to make the product adaptable. although if one is concerned, the early products starting point for mobile phone designed for the product, and its business functions to be significantly inferior to PDAs in general, only about the function of general electronic notebook, and the current system and the Palm WinCE-based products developed, collectively referred to SmartPhone, its features and handheld computer flat or higher, and also has a communication function and wireless data exchange, but also represent the direction of future development of Pocket PC.
