A PDA is a small, portable computer used for administrative tasks, communication, education, and more. PDAs evolved from early devices in the 1980s and 1990s to include features like full keyboards, mobile phone connectivity, and applications for businesses, healthcare, education, sports, and vehicle navigation. Modern PDAs integrate components like microprocessors, operating systems, memory, batteries, and input devices to power applications and wirelessly connect to the internet.

(Personal Digital Assistant)

4. 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.

5.  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

6.  Businesses and
Enterprises
 Medical use
 Educational use
 Sporting use
 Automobile navigation

7. PDAs help
businesses to track
and store details and
in supply chain
management in
warehouses and
package delivery.

8. 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

9. With PDAs students
can digitally note
down points, which
can be reviewed
immediately using the
built in dictionary and
spell checker.

10. 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.

11. 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 .

12.  Microprocessors
 Operating System
 Memory
 Batteries
 Input Device

13. 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.

14. The operating system is a
program which act as
an interface between the
user and the hardware.

15. 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.

16. 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.

17. 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.

18.  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.

19.  Motherboard
 Communication
Hardware
 Organizational Tools
 Telephone Service
 Multimedia Players
 Web Browser

20. 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.

21. 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.

22. 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.

23. 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.

24. Most PDAs now come
equipped with
multimedia players that
allow users to view
videos, pictures and
listen to their favourite
music.

25. 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.

26.  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.
