2. What is the history of the Internet?
• The design of the Internet was done in 1973 and published in 1974.
• The Internet is a worldwide network of thousands of computers and computer
networks.
• The Internet has revolutionized the computer and communications world like
nothing before.
• The invention of the telegraph, telephone, radio, and computer set the stage for
this unprecedented integration of capabilities.
• The Internet got its start in the United States more than 50 years ago as a
government weapon in the Cold War.

3. Reasons why people use the internet!
• 1st Reason. To be a part of society.
• 2nd Reason. To get information they need.
• 3rd Reason. To communicate with each other.
• 4th Reason. To relax and to have fun.
• 5th Reason. To watch movies, to read books etc.

4. Who invented the internet?
• The initial idea is credited as being Leonard Kleinrock's after he
published his first paper entitled "Information Flow in Large
Communication Nets" on May 31, 1961.
• In 1962, J.C.R. Licklider became the first Director of IPTO and gave his
vision of a galactic network. In addition to ideas from Licklider and
Kleinrock, Robert Taylor helped create the idea of a network.

5. How was the 1st generation of computers like?
•
• The 1st generation of computers was from 1940 to 1955. Computers were powered by vacuum
tubes and used magnetic drums to store data and memory.
• The vacuum tube controlled the electric current through a sealed container.
• The magnetic drum is a metal coated cylinder with magnetic iron-oxide material which stored
data and programs.
• There were many problems with the first generation computers, like many things when they
start out.
• They were very expensive to make and run, slow and had limited application capabilities.
• They also generated a lot of heat and used large amounts of electricity, the ENIAC used 160
kilowatts of electrical power.

6. The 2nd Generation
• Then in 1956, the second generation of computers hit.
• The vacuum tubes were no longer the best thing for running a
computer, the latest component to replace the vacuum tubes is a transistor.
• The transistor had a major influence on the development of electronics as it
was more reliable than the first generation.
• It made the computers smaller, faster, cheaper and more efficient to run.
• They were still generating a lot of heat which resulted in the damage of
sensitive internal parts of the computer

7. The 3rd Generation
• The era of transistors was short lived because in 1964, integrated circuits
became the next great thing in developing semiconductor technology.
• Computers were made to be more accessible and affordable to a mass
audience.
• Punched cards and printouts were replaced by keyboards and monitors and
the first operating system was created to allow multiple applications to run
on one computer.

8. The 4t
h 4th Generation
• The 4th generation is still the present generation of computers.
• When microprocessors where invented in 1971, the era of mass usage of
computers began!
• The 4th generation was started by the Intel 4004 chip.
• Microprocessors have thousands of integrated circuits on one silicon chip.
• This chip contained the CPU, memory and input/output controls – a lot
more advanced that the last 3 generations. 10 years later, IBM introduced
the first computer that was dedicated to the home user

9. How do computers look like today?
• Now computers are very thin and weight nothing for example some
two or three pounds.
Some of the newest computers are:
• Samsung - Series 5 Ultrabook 13.3" Touch-Screen Laptop - 4GB
Memory - 500GB Hard Drive
• Apple 27" iMac Desktop Computer
• My favorite is the Microsoft RT Surface

10. Where is the internet used in daily lives of
people?
• In different places such as schools, hospitals, offices, homes, etc…
• In a smart phone internet is the main point, because if it doesn’t have
internet then there isn’t that much you can do
• I pads, tablets, etc…
• Stores to keep things running
• Something I found awesome is that now you can even order your
subway sandwiches online with the free subway app.
