How does data travels from one country to another?
Most of what you see on the internet, including possibly this article, travels to you from underwater. In fact, 99\% of all international data is transferred through a labyrinth of cables stretching across the floor of the world’s oceans. There are 229 of them, each no thicker than a soda can.
How does the internet reach other continents?
Undersea cables are responsible for moving data between countries and continents at high speeds, making everything from photo sharing to financial transactions possible. These cables use fiber optics to move data at high speeds to land, where the data is then conveyed via fiber optics to homes and businesses.
Which is the fastest data transfer?
The world record for fastest internet speed has been utterly shattered as Japanese engineers have demonstrated a data transmission rate of 319 Terabits per second (Tb/s) through optical fibers.
Which data communication is used to connect abroad?
Home and visited networks “Visitor network” refers to the network a subscriber roams temporarily and is outside the bounds of the “home network”.
How are messages transmitted over the Internet?
Data travels across the internet in packets. When you send an e-mail to someone, the message breaks up into packets that travel across the network. Different packets from the same message don’t have to follow the same path. That’s part of what makes the Internet so robust and fast.

| Characteristic | Fixed broadband internet speed in Mbps |
|---|---|
| Denmark | 226.13 |

Yes, it is possible. You can get international dedicated high speed lines from anywhere in the United States to most countries. You can contract with an ISP in one of those countries for internet service. You could also establish a dial up internet connection to an ISP in another country.
Is there WiFi in every country?
Thanks to new innovations, we can now access the internet nearly everywhere in the world. It is in our reach in many places in big cities, small towns, in the woods, in the mountains, in the air, and at sea. Currently, however, internet access while traveling abroad, especially on mobile devices, comes at a premium.
Do satellites travel wirelessly in the air?
No, they don’t travel wirelessly. They travel through optical fibre cables that are laid on the floors of oceans and are called Submarine communications cable. Data travels through these at high speeds (like tens of terabits of data per second or even less) to reach their destination.

How do internet service providers (ISPs) work?
Internet Service Providers (ISPs) pick up the bandwidth and deliver it to customers, sort of like milkmen getting the milk at the dairy and delivering it to people’s homes. The larger IXPs are, the more bandwidth they produce; the closer they are to the customers, the faster the ISPs can deliver the bandwidth at a given price.
