Technology refers to tools, machines, techniques and methods used to solve problems or perform tasks. Over recent decades, technology has rapidly advanced and expanded into every field. Smartphones now function as computers, and technology has transformed medicine, allowing treatment of previously fatal diseases. While technology has made lives easier and allowed new discoveries, it also presents some risks like nuclear war, negative impacts of cell phone use, and environmental issues from pollution.

2. Technology is the making, modification, usage, and knowledge of tools, machines,
techniques, crafts, systems, and methods of organization, in order to solve a problem,
improve a pre-existing solution to a problem, achieve a goal, handle an applied
input/output relation or perform a specific function.

3. Over the last few decades, technology has been rapidly
changing and expanding in every field imaginable.
 Smart phones are now capable of acting as standalone
computer devices .
 Technology has changed our lives in so many ways it
is hard to perceive. If you look in the field of
medicine alone, technological advances have allowed
doctors to treat diseases and illness that were
otherwise at one time fatal.
 Technology is making our lives easy. We are
organized and fast with help of Technology. It is
helping us to discover and invent new things.
 One way that technology has changed our culture 3

auscultation –listening to chest sounds and
heartbeats by pressing the ear to the chest –to
assess cardiac health.
Rene Laennec in 1816, invented
STETHOSCOPE has become the singular
symbol of physicians and has become one of
the most trusted tools that physicians use for
physical diagnosis.

control the access to information and
according to him we expected.
But nowadays the technology helps us to access
and process information.

6. NEW TECHNOLOGIES ARE COSTLIER, ARE THEY WORTH IT ?
New technologies often substitute for older technologies.
The unit cost of new technologies may be higher or lower
than the cost of the older technologies they replace.
But the cost expended in the older one is totally
unworthy.

7. It Kills People.
• By Nuclear War:
• In 1945, an estimated 200,000 people
Killed as a result of two atomic
bombings in Japan.
• There is also no telling how many
nuclear weapons have been lost, sold
to other nations, or simply failed to
be accounted for. All it takes is one
person (or hacker) to change the
world forever.

8. Cell Phones:
• Wastage of Time and Money
• Negative Effects On Students
• ACommunication Tool For Criminal Purposes
• Negative Effects On Teenagers
• Negative Effects of Mobile Phone Use On Our Environment
Global Warming:
• Oil leaks in the ocean
• Gas guzzling vehicles on the road
• Smoke from the factories
• Unstoppable cutting of tries
• Threat to Ozone layer 8

9. Isolation
•Isolation means lack of contact with other people in
normal daily living, such as, the workplace, with
friends and in social activities. We isolate ourselves
by walking around in our own little world, listening
to our iPods or staring at the screen of the latest
mobile device even when we are around other
people.
• Studies have shown that people who are
socially isolated will live shorter lives.
Depression:
• Technology creates the perfect recipe for
depression with the lack of human contact,
overeating and lack of exercise.
•Some people could cure their depression by
living a healthier lifestyle. 9

10. CONCLUSION :-
There are clearly both pros and cons of adolescent technology
use. The fact is, it is important for adolescents to learn and
understand technology. Its’s become a part of daily life for all
people to use a computer or a cell phone. It is necessary in
most situations, especially for when they are older and have
jobs. However, technology use must not be excessive. Extreme
technological use in adolescent can cause all sorts of problems;
socially and physically. It is important for adolescent to
understand that yes, technology is an amazing thing: but at the
same time, it should not be used all of the time. They should
not be overly dependent on it. Adolescents need to learn that
sometimes, technology is not the right answer for a situation.
