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 their friends, also values like solidarity were more present.

Definition• The term ‘‘ technology’’is applied to the tools,

machines, and processes that use scientific advances in practical applications. Historically, it can apply to the tools and techniques employed by earlier human societies . Technology is a very broad concept that deals with human as well as other animals ‘ usage and knowledge of tools , and how it affects a species ‘ability to control and adapt to the environment a tool to make a task easier .

The Invention of Computers Computers are made up of many parts, and each one of them is a unique 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.

• 1936 : The First ComputerThe first freely programmable computer came into play.

• 1947 : The transistorThe transistor was invented by Bell Telephone Company. It wasn't a computer in itself'but it

was a vital computer component.• 1953 : IBM

• The Invention of cell phone With today's technology we can speak to people around the world almost anytime and 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.

download the pictures to a computer to be printed.

• 2007 :The Apple Iphone is releasedApple 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.

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.

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.

• 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.

Disadvantages of technology

• 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.

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.
