Nowadays, we live in rapid technological change, especially the small and simplify technology is loved by many people. Simplified techniques make the more people use the instruments of civilization easier. The USB and the iPhone may be examples.
Before the appearance of the USB devices, the ways of the connection was different each other to connect some devices to the computer. The installation process in computer is also complex. The USB technology provides the convenience and freedom of the extension to the computer. So many devices adopt the USB technology. Now we can see the various peripherals of USB interface to be easily accessible in our circumference, such as mouse, keyboard, speaker, camera, printers, and so on. To use the USB devices is very simple and just plugs a peripheral device into the computer without complex installation like before.
The biggest advantage of the iPhone is very easy to use among many points to be considered. Before the iPhone come out, the Windows Mobile operating system led the smart phone’s market. They gave us a lot of inconvenient points. In the Windows Mobile, the installation of the program was complicated and to find the Start button and the folder or path was very difficult and the speed of execution was also very slow. But the iPhone’s menu simply consists of only icons. So by only touching icon, we can download and install applications from the iTunes store. We can execute the application fast without having to click the folder or browse to the path.
In conclusion, I think that USB makes more easily using the peripheral devices to the computer and the iPhone provides everyone easy chance to get good information and use a lot of application simply. These things increase the quality of our life and give us more convenient life style.
