3. How was life before technology ?
• Many years ago, life was just more
simple. The people was focus in others
activities and they had more time for
themself.The families were more united,
humble and the people were closed to

invention on its own. In this timeline we will take a look at many of these
parts, and how they contributed to the computers we have today.

anywhere. It wasn't always this way, and it was made possible in part by cell
phones. This timeline outlines how cell phones came to be.

Apple released its first iphone and it changed the cellular industry. It featured a touch screen
and allowed users to do almost anything they could do from a home computer, which
basically changed the way people lived.
16. What Has Technology Done for us?
• It makes it easier for people to
communicate with others. It also makes it
easier for us to buy and sell things. People
can take tests, do homework, listen to
music, drive instead of walk everywhere,
and talk to people over long distances.
Technology was made to make life easier for
humans and that's some of the ways it helps
humans.
17. How Has Technology Changed
Society?
• There are so many ways that technology has changed
society that it is hard to even count them all. Simple
things make everyday life easier for millions of people.
Computers provide entertainment and allow us to
communicate quickly with people around the world in
seconds . We can now communicate with anyone
around the globe by simply text messaging them or
sending them an email for an almost instantaneous
response. GPS allows us to know where we are on a
trail in the woods, while driving our car we can get
directions.
18. • Today, we can’t imagine ourselves without
technological advances such as cars,
medicine, microwaves, cell phones,
computers, and televisions. However,
technology won’t stop here, but develop
further. As technology develops, there are
not only advantages, but disadvantages
from them.
20. • Addiction: Several people, get addicted
to the technology and this is a big problem,
because they get a life based in material
things.
• Work: People will loose their jobs and
be replaced by machines that will do
the work for them. In addition,
machines and robots are too complex for
most people to use.
21. Where are we going?
• technology is making machines that
could help us with our works, for
example robots that could help to
save lives in accidents.
Also with the technology, we are going
with an advance future, for example,
technology able to open a new
world, with communications and to
discover even new planets.
