How the Web Works
The modern life would have been impossible without the modern technologies and especially without the Internet. This is what made our life and out economies to grow and to develop so quickly. We all can make business today with people who live all around the world. We can share ideas, find new methods to solve problems, work and have fun together.
So, how the internet works and why is it so popular these days?
The internet is a technology that connects different computers all around the world. The information that they share however, is not on the web, like many people think, but it is on big computers with amazingly big memory called servers. These servers are the base each web site uses to function. So, when you upload something on Youtube or on Facebook, you actually upload that image or video on the server and it stays there till the moment you delete it or the moderators delete it.
And this is how the web works:
Your computer is connected to server that is connected all the others. This way everyone share information with the others and the place where this happens is virtual, it does not exist in the real world. However, despite that, we can see it and we can communicate because of it. So, it may does not exist but it changes our world for real.
Now, when we know how the Internet works we can explain exactly how the cheap international calls from mobile can be made by using the Internet.
Your mobile phone can be connected to system on the web by dialling a special number. This way your call is directed to the server of the telecommunication company. After that, when you dial the number you want to call, the system redirects you and makes your call. This technology is called VoIP.
So, next time when you use VoIP to make your cheap international calls from mobile, you will know how the system works.
