Imagine that you are sitting in a park and suddenly remember that you need to send an urge

Imagine that you are sitting in a park and suddenly remember that you need to send an urgent email. You have your laptop computer with you and you connect it to a wireless access point and access the Internet. Then you send your email. This wouldn’t have been possible if there were no wireless Internet for laptops. Wireless Internet has come into our life in so many ways that we don’t even realize what a necessary part it has become of our day-to-day lives.
How do we connect to a wireless Internet service for laptop computers? There are two ways to do this. They are Wi-Fi connection and Bluetooth connection. Wireless networking is very easy. You just switch on the Wi-Fi button that has been provided in the laptop for Wi-Fi scanning. Once that is done, the computer will connect to the Internet.
An interesting fact about Wi-Fi networking is that you can create a network between similar wireless equipment. Consider a situation where you and your friend both have Wi-Fi laptops, and there is some data you want to exchange. Traditional networking architecture demands that you have a wireless router (路由器). But the beauty of Wi-Fi networking technology is that you can set up a network between you and your friend’s laptop, and share all the data you want.
Broadband (宽带) Internet connection is typically preferred by any user as it provides better speed for Internet surfing. Up until the invention of 3G mobile phones, Internet speed on mobile phones was very slow. 3G has the promise of changing the entire face of broadband technology. Just imagine browsing at speeds of more that 2MB per second. To give you a measure of the speed, 3G enables you to watch high quality live videos on the Internet.
It is amazing to see how technology changes and the rate at which it changes. There may come a time when you may be able to browse using mobile wireless Internet for laptops anywhere in the world.
