PDA Mobile Phones
Since the day of its inception, the mobile phone has constantly evolved with newer technology and repackaged itself with more and more features. PDA Phones (personal digital assistant
) is a very special type of phone. that have the features of mobile phones , computers . Apple was the first company that
introduces PDA Phones . PDA is also called as palmtop or palm computers.
PDA Phones
or Personal Digital Assistants are hand held
devices that act as mini computers. For this reason PDAs are also
called Pocket computers or Palm Top computers. The PDAs were originally
designed as Personal organisers and over the period of time been
endowed with many hi-end features.
PDAs have built their reputation on their ability
to accommodate versatile usages. A PDA can be used as a calculator,
clock, calendar, for accessing internet, sending / receiving messages
& emails, typwriting, word processing, playing games, video
recording, making documents and spread sheets and taking the advantage
of GPS etc. Almost everything that your desktop computers are
capable of handling, but with a much greater mobility.
Unlike the first PDA, the newer models of this
genre are empowered with colour screen and audio capabilities.
This enables the PDAs to assume a 3fold personality, such as that
of a smartphone web browser and portable media player. Many PDAs
are such a make that they can access the internet/ extranet/ intranet
through the Wi-Fi or wireless Wide Area Network (WWANs).
One of the most significant feature of a PDA is
the existence of a touch screen. Other typical features of a PDA
includes memory card slot for data storage and IrDA port for connectivity.
The newer PDAs also comes with a Wi-Fi and Bluetooth power.
The Touch screen PDAs, have a detachable stylus
that is used to operate the device. Interaction is done by tapping
the screen to activate Menu or button choices. For text input,
there is either virtual keyboard, where input is done by tapping
the letters, or there is the power of letter or word recognition.
PDAs for the serious business usage include Blackberry Phones
and Treo. These handsets have full QWERTY keyboard and have scroll
wheels or thumb wheels to facilitate data entry and navigation.
There is also the advantage of full sized folded keyboard, and
push based email support.
Newer PDAs such as iPhone uses a novel technique
for inputs such as Multi-Touch, where fingers are used to type.
Most of the newer PDAs also have memory card slots in them. In
terms of connectivity, the modern PDAs are enabled with Bluetooth
wireless connectivity. As one peruses through the mid range PDAs,
one will find Wi-Fi as well. Here it should be observed that most
universal PDAs will use infrared as the option, as it is economical
and all PDAs have it.
Most PDAs come with the ability to synchronize
to a PC. This is done with the help of synchronization software
provided with the handheld, such as HotSync Manager. These softwares
also help PDA to be synchronized with a Personal information manager.
For instance the BlackBerry PDA Desktop Manager program which
can synchronize to both Microsoft Outlook and ACT!. While still
the others come with their Proprietary softwares.
Just as a personal computer, it is also possible
to customise the PDAs. Which means that you can put in additional
softwares in the device. With such power, it is but evident how
the PDAs have carved a niche for themselves. As per a survey,
the overall market for PDAs grew by 20.7% in the third quarter
(Q3) of 2005.
