Communication: email, chat rooms, social networks and video-conferencing.
Sharing information: text, images, maps...
Playing games: online and downloadable games.
Banking and shopping.

HOW TO USE THE INTERNET:
What do you need to connect to the Internet? A telephone line, a router, an Internet service provider (ISP), a web browser.
What's a browser? A browser is a computer program that we use to connect to the Internet: Internet Explorer, Chrome, Firefox...

You introduce a keyword and the search engine gives you a list of links: words or images that take you to web pages with information pages, shopping pages, photos...

HOW DO COMPUTERS WORK?

A computer is a machine that can be programmed with instructions. Computers receive information (input), they carry out a process and they produce output.
HISTORY OF COMPUTERS: The first computer was invented in 1943. It was used to break the codes used by the German army to send messages during World War II. It's name was Colossus because it occupied a whole room.

TYPES OF COMPUTERS:
General purpose machines: they can perform many functions: mobile phones...
Special purpose machines: they perform one specific function: GPS...

HOW HAVE INVENTIONS CHANGED ART AND MUSIC?

Many artists now use computer software to produce their work. Musicians digitalise music, so they can change the pitch and tone of the music by using modern technology. Digital recording makes it possible to mix different tracks to produce a new version of as ong. Instruments can be added or removed from the recording.

Other artists use modern software and technology to produce digital images. They use stylus and touch-sensitive pads to draw or to edit digital images.

WHAT INVENTIONS DO WE USE IN OUR DAILY LIVES?

Inventors design machines to solve problems or to make something easier to do.
Modern machines have changed the way we live in many ways:

• Food production: machines have changed the way the food is prepared in large factories, sometimes it has been frozen or packaged in a tin, so it stays fresh for longer periods of time.

• Clothing: most of our clothes contain synthetic fabrics (nylon, viscose). So they're cheaper, more resistant to temperature than natural fabrics and they do not wear out so quickly. 
• Healthcare: Doctors use microscopes, computers, X-ray machines and scanners...
