2. Internet : Characteristics

Do not mix up the World Wide Web and the Internet. They are not the same thing.

What is it?

The Internet is a vast computer communication network spanning the globe using a common protocol called TCP / IP which is short for Transmission Control Protocol / Internet protocol.

Does anyone own it?

No one actually owns the Internet because it is a 'network of networks'. Individual organisations, companies and governments own their particular particular network which are connected to thousands of other networks to form the Internet. The key is that they all use the common TCP/IP protocol so they can communicate.

What makes it work?

There are companies called Internet Service Providers who provide every-day users with the connectivity they need to get on the Internet. Connection can be made by normal telephone line using a home router.

Businesses wanting a faster connection use a leased line. Connection can also be made through the mobile phone network.

There are major telecom companies who provide the 'backbone' of the system. They own the communication equipment, cabling, satellite and undersea data links that make it all work.

Then there are 'content providers' in the form of web sites, video services, telephone services that are the reason people want to use it in the first place.

Think of the internet as an 'enabling technology'. It does nothing of itself, but brings people, companies and organisations together so they can interact.

The Internet is an 'open' network because any computer with the appropriate communication equipment can connect to it.
