Sources of Information: - Internet: - http://www.google.co.in http://www.computing.net http://www.wikipedia.org http://www.qarchieve.org http://www.pdaselect.com Project Details Overview of PDA : Definition A personal digital assistant (PDA) is a handheld computers, also known as a palmtop computer. 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. Overview of PDA Overview of PDA : History 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 January 7, 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". PDA Operating System Linux, PalmSource’s OS, Pocket PC (Windows CE) from Microsoft, Research in Motion and Symbian OS (formerly EPOC) are major PDA operating systems Overview of PDA CASIO PF-3000 Overview of PDA : Typical features Touch screen: Memory cards: Wired connectivity: Wireless connectivity Synchronization: Overview of PDA Uses of PDA : Automobile navigation Many PDAs are used in car kits and are fitted with differential Global Positioning System (GPS) receivers to provide realtime automobile navigation. PDAs are increasingly being fitted as standard on new cars. Uses of PDA PDAs are used to store information that can be accessed at any time and anywhere Uses of PDA : Educational uses Educational institutes have commenced a trend of integrating PDAs into their teaching practices (mobile learning). With the capabilities of PDAs, teachers are now able to provide a collaborative learning experience for their students PDAs and handheld devices have recently been allowed for digital note taking. Uses of PDA Uses of PDA : Sporting uses PDAs are used by glider pilots for pre-flight planning and to assist navigation in cross-country competitions. They are linked to a GPS to produce moving-map displays showing the tracks to turn-points, airspace hazards and other tactical information. Uses of PDA Uses of PDA : PDA for people with disabilities PDAs offer varying degrees of accessibility for people with differing abilities, based on the particular device and service. People with vision, hearing, mobility, and speech impairments may be able to use PDAs on a limited basis, and this may be enhanced by the addition of accessibility software (e.g. speech recognition for verbal input instead of manual input). What are PDAs most commonly used for? 1)Calendar/Date Book, 2)Address Book/Phone Book, 3)To do/Lists, 4)Memos/Notes, Traditional Word and Excel documents Not enough? Dictionary, Games, eBooks, Navigation, Encyclopedia, Universal Remote Control, Music, Movies, Internet List goes on…….. Uses of PDA Working Mechanism Of PDA : Microprocessors Like standard desktop and laptop computers, PDAs are powered by microprocessors. The microprocessor is the brain of the PDA and coordinates all of the PDA's functions according to programmed instructions. The Operating system The operating system contains the pre-programmed instructions that tell the microprocessor what to do. Memory A PDA doesn't have a hard drive. It stores basic programs (address book, calendar, memo pad and operating system) in a read-only memory (ROM) chip, which remains intact even when the machine shuts down. The data and any programs that are added later are stored in the device's RAM. This approach has several advantages over standard PCs. Batteries PDAs are powered by batteries. Some models use alkaline (AAA) batteries, while others use rechargeable batteries (lithium, nickel-cadmium or nickel-metal hydride). Working Mechanism Of PDA Working Mechanism Of PDA : LCD Display PDAs have some type of LCD display screen. Unlike the LCD screens for desktop or laptop computers, which are used solely as output devices, PDAs use their screens for output and input. Input Device PDAs vary in how the mode of inputting data and commands. Hand-held computers typically use a miniature keyboard in combination with a touch screen. Input/output Devices Because PDAs are designed to work in tandem with a desktop or laptop, they need to work with the same information in both places. If an appointment is made on the desktop computer, it needs to be transferred to the PDA; likewise if a phone number is noted on the PDA, it should be uploaded to ones PC. Everything on the PDA has to be saved to a desktop computer in case the batteries go dead in the PDA. So, any PDA must be able to communicate with a PC. The communication between PDA and PC is referred to as data synchronization or syncing. This is typically done through a serial or USB port on the PDA.

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. Future Trends In PDA Development Future Trends In PDA Development : Some of the widespread PDAs used are Acer N Series, BlackBerry, HP iPAQ, iPhone and Nokia E Series.
