Simply put, the Internet is a collection of millions of computers around the world that are connected between each other. Media connections that can be used through a phone line, fiber optic (fiber optic), coaxial cable (coaxial cable), satellite or wireless connection.
When we logon (in this case connected) with the Internet, we are given the right of access to other computers around the world connected to the internet also. With the rapid advances in technology, the current Internet can be contacted with a wireless connection from the handheld PC or a notebook computer.
Once connected to the internet you can do several things, such as: send and receive email, chat with text or voice media, surfing (surfing) on the World Wide Web, or anything else with a particular software application.
Simply put, the way the Internet works the same as the postal system or parcel delivery system, but the Internet works very quickly.
For example, if we are now in Surabaya and will send an email to America, after we press the Send (Send) before the next email we will be heading to the mail server. (Mail server is a computer that is normally not we use today, but part of the services available on the Internet, so we can just get out of the Internet after pressing the Send button without interrupting the process of sending the email). Then, the mail server we are going to try to contact the mail server in the U.S. through the route Jakarta - Singapore - Japan - United States or if the route can save a busy route Australia - America.
Data packets in the Internet has a certain size so that when we had quite a large email may be divided into several packets and each packet can be sent by a different route. After arriving in America, the mail server there will rebuild our email into one whole piece ready to be served.
When the satellites used in the routes the mail server busy we will try to post back after a while to actually sent. When up to a maximum of up to 4 days (depending on our mail server settings) the email can not be sent the email will be sent an email notification that we did not get.
The route should pass the data packets on the Internet is very long and involves a lot of computers around the world, so that when we submit the data are personal data and / or important, you should use a secure server, the server is equipped with data encryption before sending data facility to another computer and decrypted when it receives a packet from another computer.
