CONCLUSION
Overview
A PDA ( Personal Digital Assistant) is basically a small computer that can be used
for administrative applications, communication
and collaboration, and teaching and learning
applications. A PDA may also be referred to as a handheld device, a Palm, or a Pocket
PC.
HISTORY The first PDA was released in
1986 by Psion, the Organizer II. It also had a full keyboard. The term PDA was first used on
January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada.
In 1996, Nokia introduced the first mobile phone with full PDA functionality, the 9000 Communicator.
Uses of PDA
Businesses and Enterprises
Medical use Educational use Sporting use Automobile
navigation
Businesses and Enterprises
PDAs help businesses to track
and store details and in supply chain
management in warehouses and package delivery.
Medical
PDA enhances the communication between
patients and doctors. With PDA, doctors can easily track patient data and history. This
helps in easy and fast diagnosis of any ailments.
Patients, on the other hand, can use PDAs to record their
symptoms, which helps doctors to provide treatment
immediately
Education
With PDAs students can
digitally note down points, which can
be reviewed immediately using
the built in dictionary and spell checker.
Sports
PDAs are very useful in cross-country
competitions be it road rally, bike rally, or
trekking. It serves as the 'third eye' as it helps to
navigate in unknown places and locations.
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 and dynamic
routing .
Working Mechanism of PDA
Microprocessors Operating
System Memory Batteries Input Device
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.
Operating System
The operating system is a program which act as an interface between
the user and the hardware.
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.
Batteries
PDAs are powered by batteries. Some models
use alkaline (AAA) batteries, while others use
rechargeable batteries. The battery life depends on what kind of PDA one
has and what it is used for.
Input Device
Hand-held computers typically use a miniature keyboard in
combination with a touch screen. Palm-sized computers use a stylus and touch screen
exclusively in combination with a handwriting recognition
program.
Future Trends
The uses of PDA has visibly increased.
It is the PDA’s ability to enable work in different environment and different purpose.
The wireless connectivity of the next generation of PDA using Wi-Fi and Bluetooth supports the extension and direction of future application.
Components Of PDA
Motherboard Communication
Hardware Organizational Tools Telephone Service Multimedia Players Web Browser
Motherboard
It allows all other components of the PDA to communicate with one another and regulates any
user commands that tell the PDA what to do. The motherboard
contains the processor and other components necessary for the
PDA to function properly.
Communication Hardware
Communications hardware for wireless Internet and Bluetooth technology is increasingly common in modern PDAs. Most PDA manufacturers also make antennas and modems for
such communications.
Organizational Tools
Personal digital assistants were first created as a means of
organizing contact information, scheduling meetings and keeping
track of work and daily schedules. PDAs offer a variety of organizational tools. They contain calendars that can be updated by
users to remind them of upcoming meetings,
appointments and events.
Telephone Service
Personal digital assistants have evolved to include other services such as telephone service. Most people have a combined phone
and PDA, also known as a Smartphone. These devices allow
users to place calls, receive voicemail and send text
messages.
Multimedia Players
Most PDAs now come equipped with
multimedia players that allow users to view videos, pictures and
listen to their favourite music.
Web Browser
PDAs come with a pre-installed Web
browser that will let you check email and
surf the Web. Because of this, most PDAs require you to sign up for a data
plan.
CONCLUSION
Computers are the guides to the Information Age. Over the years, they have assumed the role as administrators of data
PDAs are the solution to this vision of ubiquitous computing
These devices represent a new step in computer technology.
PDAs are no different. But, eventually, they will fulfill their original purpose of being "all-knowing" and "all-doing" devices.
