What Is Internet?

I asked some peoples for this.
And their Answers are:

• ‌The internet is like a popular thing.
• ‌Some satellites up there.
• ‌I picture it in my head with like waves of internet going to the phone.
• ‌Somebody told me a cloud once.
• ‌The internet is a lot like plumbing it's always moving.

Most people don't have any idea where
the internet came from and doesn't matter, they don't need to. It's sort of like asking who invented the ballpoint pen,or the flush toilet, or the zipper.These are all things we just use every day we don't even think about the fact that one day somebody invented them.

Vint Cerf and Bob Kahn (1970)

So the internet is just like that. Many, many years ago in the early 1970s Vint Cerf and Bob Kahn began working on the design of what we now call the internet.It was a result of another experiment called the ARPANET which stood for Advanced Research Project Agency Network. It was a Defense Department research project.

Paul Baran was trying to figure out how to build a communication system that might actually survive a nuclear attack. So he had this idea of breaking messages up into blocks and sending them as fast as possible in every possible direction through the mesh network.So They built what eventually became a nationwide experimental packet network, and it worked.

A Distributed Packet-Switched Network System.

In simple words

It is a telecommunications network that uses telephone lines, cables, satellites and wireless connections to connect all to the World Wide Web. All modern computers can connect to the internet, as can many mobile phones and some televisions, video game consoles and other devices.

It can be used to:

• Access a huge 'library' of information from the millions of websites around the world that make up the World Wide Web
• Send and receive email messages
• Share photographs and video clips with your friends and family
• Buy goods and services (and often save money!)
• Carry out online banking
• Use Skype to make free phone calls to other computer users
• Play games with other people online
• Catch up on TV and radio programmes that you've missed – or watch them again
• Learn something new with an online course.
