21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better.

First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute¹ lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently².

Also, internet is another useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. The internet leads us to a place where we can find unlimited³ information and resources. It makes our life much easier and better.

The last technology is cellphone. Nowadays, many people have a cellphone. But it just appears on the market for about 10 years. It is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. Also, we can communicate with others by making a phone call instead of sending letters. It is very fast and useful way to communicate.

In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future.
