Top 5 Gadgets That Changed The World

5.Computer

Computers have changed the world in many ways.  They allow huge amounts of information to be stored in a small space.  They also allow a person to calculate mathematical problems with ease.  Finally, computers allow people to communicate with one another through internet sites such as Facebook, My Space, and Twitter.

Personal computers today can hold up to 32 gigabytes of memory.  They can be used to store music, pictures, documents, videos, and much more.  Computers are able to be reprogrammed to suit any user's needs.  This is one of the key traits of a computer today.

Computers were first designed to help a person calculate numbers; this function can be seen as far back as 2000 B.C. with the use of the abacus.  Modern computers are simply very advanced calculators.  Almost any mathematical function can be plugged into a computer, and the computer will solve almost instantaneously.  The use of a computer as a calculating device takes away the monotonous task of calculating by brute force.

Finally, computers have changed the way that we communicate as a society.  People can now talk to one another in almost no time at all through the use of social networking sites, and people can even live video chat with applications such as Skype.  Imagine, if this idea had been presented to scientist 50 years ago, the presenter would have been laughed out of the conversation.







4.Hypodermic Syringe

The hypodermic syringe, along with the needle have helped change our world in both bad and good ways. It has given us so many more medical opportunities and health advances. Whether you're a doctor, diabetic or even heroin addict, the hypodermic syringe has helped you get to where you are today.




3.Television


The impact of TV is that it brought information right to your house.People were able to communicate better, address issues faster and become aware of things happening around the world by watching things like the news. The down part is that it made people lazy(not that they weren't before) but it increased our chance of sitting at the couch and watching TV for hours and hours. people are less active, distracting kids from doing their home work and making them lazy not going outside and play and exercise. people also consume junk foods while watching TV and u know that is part of the reason that people are NOT being healthy

2.Radio

Radios have been one of the more important technological devices for more than a century. From their beginnings in the early 1800's until the new developments in recent years, radios have helped to provide communication as well as entertainment throughout the society of many cultures.
The early years of the radio technology began early in the 1800s, but the actual invention cannot be attributed to only one person. During this time period, several inventors created and improved upon the technology that became the radio as we know it today. Once referred to as “wireless telegraphy,” radio technology has always included electronic signaling between a transmitter and one or more receivers. In order to accomplish this, there are many several pieces of technology that fit together.
The first major breakthrough in the radio technology occurred in 1895 when the first patent for the radio was granted to Guglielmo Marconi. Though the idea was around, the actual devices that made the technology possible was not readily available until 1901. For this era, the radio technology was limited to communications with ships in case of an emergency. In 1907, the first commercial transatlantic radio service was created. From there, the technology continued to draw interested engineers and inventors from all sorts of industries.




1.Smart Phones


Smartphones have changed the way Americans communicate. More than a phone, a Smartphone is considered as a handheld computer which has multiple features to run the applications. With the always on and fast internet connection, gone are the days, where people had to access the internet only at homes. A smartphone is considered as a phone which performs the functions of both camera phone and a Personal Digital Assistant (PDA).

There are many companies which provide Smartphone mobile services. Apple, Android, Windows Mobile, Palm, Blackberry and Symbian are few such applications which provide smartphone services using different platforms and different operating systems. With the introduction of iPhones from Apple, the smartphones have become affordable and being used by large number of people. There are varieties of applications available in these smartphones. The users of iPhone and Blackberry can call a Toll-free number and record memos, seeking for area code listing , scheduling appointments, etc. The software recognizes the message and sends reminder notes through IM or emails. Apart from this, iFitness, fast food calorie counter, iBreath, Memory Jogger, etc are some of the applications which can prove to be very helpful for Smartphone users.
