In the 19th and 20th centuries the World has faced the industrial and the computer ages, which optimized greatly our work with the help of machines and computers.

In the beginning it was a very difficult development, but once the progress started it continued increasing its speed and quality.

As a result the World has changed much more than people thought possible.

Ada Lovelace – the first computer programmer

in 1979 a modern computer programming language was named ADA

1930s Konrad Zuse made the Z1

Alan Turing was born in 1912 studied mathematics at

Cambridge University in 1939 began to work for the

• 1957 - IBM made the 610 Auto-PointThe history of PC

Bill Gates and Microsoft Was born in Seattle in 1955 Bill Gates and Paul Allen left university early and started Microsoft MS’s 1st big success came in 1981 MS made their own operating system which used pictures – they called it Windows MS became the most successful company in computer software

Humans against computers

Are they really more powerful and more intelligent than humans?Do they really think in the same way that humans think?Can they go wrong and start to do frightening and dangerous things?

They can:-do millions of calculations every second;-play chess and look at 200,000,000 different chess moves;- even create pieces of music, etc.!!!

Note:

No one computer has passed the Turing Test yet… created by man.

The InternetYear Inventor Invention1970s the Internet began as a way to send information from one computer to

another

early 1990s Tim Berners-Lee (UK) Web

1995 Pierre Omidyar (USA) Auction Web = eBay

1996 Larry Page and Sergey Brin (USA) Google

1997 Ilya Segalovich and Arkady Volozh (Russia) Yandex

1998 Tom Hadfield (USA) Soccernet

2005 Alex Tew (UK) Million Dollar Homepage

The Internet is great way to:

Share information and ideas

Copy music, video, pictures, etc.

Communicate

Find

Download documents

and lots of other cool things… but you should know how to get profit from the global net.

Buy and sell

Travel

Getting the message 1774 - the 1st telegraph machine 1840s - telegraph with Morse code 1920s – the telex 1980s – e-mail messages from

one PC to another by the same e-mail system

1990s – messages by the Internet

late 1990s – text messages by mobile phones

Mobile phones have changed the lives of people all over the world!

Let’s watch the evolution of the mobile phones…

Viruses

A virus is a kind of computer program, that moves from onecomputer to another anddamages the computer’smemory or other parts of the machine.

And we shouldn’t forget the history of Computer Gaming

Spacewar and Adventure started the 2 most important kinds of computer games: - with fast action- with stories and imagination

Computer crime

Usually they do it by e-mail…the e-mail pretends to be from a large, well-known company that asks the victim to go to a company website and put in their name, account number and other information.

Using the Internet criminals can get victims’ addresses, the numbers of their bank accounts and so on

Over the last 50 or 60 years the world has changed

greatly due to information technology.

It has changed much more than people thought possible,

and I don’t like it…

I really love it!!!
