The full name of PDA is personal digital assistant, that is, personal digital assistant. It is generally called a handheld computer.
PDA is a self-developed industry. There are also handheld computers with only PDA functions without mobile phone functions on the market.
There are several simple standards for dividing PDA mobile phones and ordinary smart phones.
1. The current PDA mobile phone should be a Windows Mobile phone or a Palm OS Operating System mobile phone.
2. The screen must support handwriting
3. Support for extended memory cards
4. Windows Mobile Phones must have a resolution of 240*320 or 480*640. I don't know much about palm.
Some smartphones and PDAs are not very different, but there is something to tell you carefully. PDA (or PDA mobile phone) is very powerful. For example, you can type word or Excel on a PDA. Ordinary smart phones have very weak functions, or it cannot be done at all.
The two mobile phones are mainly software differences. For Sony Ericsson P800/900 series machines, they use the Symbian system. The screen can be hand-written or the memory card can be added, but compared with the two systems mentioned above, the software support provided by the Symbian system is far inferior to that provided by the Palm OS and Windows moblie. Especially for Windows Mobile systems, the number of software has gained the upper hand over the past one or two years.
In fact, it is difficult to determine whether a smartphone or a PDA is used in a general sense. A pda mobile phone is also a smart phone. It is more intelligent and easier to use than a smart phone. Software is its strength. The main reason to buy a PDA mobile phone is to expand the software in the future. The screen of the PDA mobile phone is also superb (generally 3.2 to 4-inch, I don't have the mobile phone function of the PDA is 4-inch, it looks great)
Currently, da is a famous mobile phone manufacturer. The product is 600/800 series mobile phones. It should be noted that the Windows Mobile system is used for mobile phones of the 500 series, but it is a phone edition, which is far from the PDA version. It cannot be regarded as a PDA mobile phone.
The full name of PDA is Personal Digital Assistant, which is a digital device used to process personal transactions. PDA products on the market can be divided into electronic dictionaries and electronic notebooks. The handheld computer is called palmsizepersonalcomputer. It is a member of the Computer family and can be placed on the palm of your hand. It provides various software and communication devices that can be used by users. It is a real PC with the Internet browsing function.
I basically agree with the upstairs statement. However, the full name of the handheld computer is Pocket PC (PPC for short), which is more functional than PDA. Generally, PDA can send and receive emails, schedule, and other functions, PPC now generally supports Wi-Fi, also known as the 802.11b standard. As long as it is within the range of hot spot signals, it can access the Internet free of charge. The theoretical bandwidth can reach 11 m.
