BTT 10 - The Internet
How do computers communicate?
Think about all of the computers that are connected in your school. Such a group of computers is called a network. Computers in a network can communicate with one another. Many schools around the world have networks. So do businesses, universities, and governments. All of these networks are connected to one another in a huge worldwide network.
This network of networks is called the Internet.
What is the internet?
The internet is a world-wide network of computers through which users can access a wide range of information, services and communicate electronically with people all over the world via telephone lines, cable lines, satellites, with their mobile device, or a variety of other ways. The
Internet is made of millions of computers around the world.
How does the Internet work?
Being connected is not enough. Computers must also understand one other. Just like people, they must speak the same language in order to communicate. They use a language called hypertext mark up language, or “html”. Computers connected to the Internet exchange instructions that allow them to “talk” to one another.
How do we connect to the internet?
We connect to the internet by paying a subscription fee to an internet service provider, or an ISP.
An Internet service provider (ISP) is a company that provides access to the Internet. ISPs directly connect customers to the Internet via telephone lines, cable lines and satellites or wirelessly . The
ISP provides us with the ability to connect to the internet through them for a price that they determine.
When connected to the internet, we send and receive data every time we click a mouse button. Every time you stream a youtube video, you are in effect using up bandwidth .
Bandwidth is the amount of information you are allowed to transfer over the internet.
Who owns the Internet?
People, schools, and businesses own different parts of the Internet. These parts include computers, cables, and other equipment. However, nobody owns the whole Internet. The
Internet is shared. Anyone who pays a fee can use it.
