4. Electronic Numerical Integrator And Calculator (ENIAC)
Built at the University of Pennsylvania between and 1945 by two professors
On the premise of replacing all computers!
Women employed calculating the firing tables for the army's artillery guns
Filled a  6 by 12 meter room, weighed 30 tons!
A “Female Computer”: “I was astounded that it took all this equipment to multiply 5 by 1000”

5. Circumference = 3.14 * diameter
To perform
Circumference = 3.14 * diameter
on ENIAC you had to rearrange a large number of patch cords and then locate three particular knobs on that vast wall of knobs and set them to 3, 1, and 4

8. MIT Media Lab in Boston
One of the first and best known institutes that studied multimedia
Innovative applications
Personalized newspapers
Life-sized holograms
Telephones that chat with callers
– ...

9. Great Impact of Multimedia
Integrating all media in the computer allows using the existing computer power to represent information interactively.
This can, also, be transmitted over computer networks.
