The Advantage And Disadvantage Of Pda

The Personal Digital Assistant has plenty of functions and it is very easy to use PDA which can meet your daily needs such as reading, playing game, dictionary, recording or watching TV. It can not only be used for managing personal information like address list and agenda, but also can be used for surfing the Internet, writing and receiving email and fixing. What is more important is that it can be used as a cell phone. All of these functions are offered by WIFI.

Just like the name of palm computer, it is like to our computer in many ways. For example, it also has CPU, memory, VGA controller and operating system. And just like the computer has the Mac group and Windows group, PDA also has Palm group and PPC group. Obviously, the biggest difference is the operating system. In spite of this, the most functions of PDA are the same. The leading functions are recording, document editing, playing game and multimedia. And it can be used for reading and picture processing if users add some PDA gadgets.

The advantages of PDA are the powerful functions without doubt:

Recording: the PDA cab record the whole meeting, reporters interview or laughter in daily life. And it support two kinds of recording formats: PCM and Mobile Voice, the later can record voice for several hours.

Pocket size dictionary: this dictionary includes more than 15 million of words. Users can recite the English word at anytime and anywhere, they will find their vocabulary will become bigger and bigger.

Reminder: the PDA contains various kinds of functions like the reminder with blinking light-emitted diode, vibration, sound or reminder on the screen. Users can set up different music according to different things.

Recreation function: people can not work at all times, but some of them can not have enough time to relax themselves. So how to spend the pieces times is very important, and the PDA must the best choice. You can find many popular functions like reading, listening to music, playing games and watching movie in it.

I believe the most useful function is the Bluetooth technique which is used for replacing short-distance wireless connection in some electric equipment. The Bluetooth technique can help users to simplify the communication between computer, cell phone and PDA. Of course, the computer also needs to be equipped by some computer widgets.

However the disadvantage of PDA is the short standby time and unstable third-party software. Many people complain that they should use more than 10 hours for charging, but they can just use PDA for three hours at most.
