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.
