A PDA is handheld computing device that allows I/O operations on data. A PDA normally contains at least one database with names and addresses book, to-do list, memo pad and notepad. It also holds a library of medical information and helps manage your patients and manipulate medical data. Additional features of a PDA usually include networking wireless communication features, voice recording and telephone/fax integration. The first PDA is considered to be the CASIO PF-3000 released in May 1983.GO Corp. was also pioneering in the field. The term was first used on January7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. PDAs are sometimes referred to as "Palms", "Palm Pilot", or "Palm Tops".

Usesareof to store information that can be accessed at PDA PDAs used

any time and anywhere.

Automobile navigation

Many PDAs are used in car kits and are fitted with differential Global Positioning System (GPS) receivers to provide real-time automobile navigation. PDAs are increasingly being fitted as standard on new cars. Many systems can also display traffic conditions, dynamic routing and roadside mobile radar guns. Some popular softwares for this functionality in Europe and in America are TomTom, Garmin, iGO etc. they are used for showing road conditions and 2D or 3D environments.

Ruggedized PDAs For many years businesses and government organizations have relied upon rugged PDAs also known as Enterprise Digital Assistants (EDAs) for mobile data applications. Typical applications include supply chain management in warehouses, package delivery, route accounting, medical treatment and record keeping in hospitals, facilities maintenance and management, parking enforcement, access control and security, capital asset maintenance, meter reading by utilities, and "wireless waitress" applications in restaurants and hospitality venues. A common feature of EDAs is the integration of Data Capture devices like Bar Code, RFID and Smart Card Readers.

Working Mechanism of PDA The working mechanism of a PDA is explained in terms of networking and database management as described below.

Wired connectivity While many earlier PDAs connected via serial ports or other proprietary format, many today connect via USB cable. This served primarily to connect to a computer, and few, if any PDAs were able to connect to each other out of the box using cables, as USB requires one machine to act as a host functionality which was not often planned. Some PDAs were able to connect to the internet, either by means of one of these cables, or by using an extension card with an Ethernet port/RJ-45 adaptor and ALSO

Wireless connectivity Most modern PDAs have Bluetooth wireless connectivity, an increasingly popular tool for mobile devices. It can be used to connect keyboards, headsets, GPS and many other accessories, as well as sending files between PDAs. Many mid-range and superior PDAs have WiFi/WLAN/802.11-connectivity, used for connecting to Wi-Fi hotspots or wireless networks. Older PDAs predominantly have an IrDA (infrared) port; however fewer current models have the technology, as it is slowly being phased out due to support for Bluetooth and Wi-Fi. IrDA allows communication between two PDAs: a PDA and any device with an IrDA port or adapter. Most universal PDA keyboards use infrared technology because many older PDAs have it, and infrared technology is low cost and has the advantage of being permitted aboard aircraft.

Components of PDA

The following softwares are some of the basic components of a PDA: Avira AntiVir Mobile for Pocket PC 6.41.00.09 PDAs, smart phones and mobile phones are increasingly becoming multifunctional devices. It has long been possible to store documents with them, to manage appointments, correspond by email and surf the Internet. This versatility makes them a rewarding target of viruses and malware. With Avira AntiVir Mobile security solutions, mobile terminals remain reliably protected against digital attacks.

Future Trends of PDA With an overall progress of a round figure of 25 years of development, PDAs are still looking further to the next generation of development. Since the first PDA which is considered to be the CASIO PF-3000 released in May 1983, till now PDAs have come up with a lot of advancements in the new-age technology, yet they are a growing or better to say an emerging technology. Some of the widespread PDAs used are Acer N Series, BlackBerry, HP iPAQ, iPhone and Nokia E Series. Some other popular PDAs are given below:
