Computer memory VS Human memory

*How much time do you need to memorise this text?

“walking westward in the morning the sun follows me from behind.

walking, I follow my drawn-out shadow before me.the sun and I don't argue about which one of us creates

the shadow.the shadow and I don't argue about which one of us must

lead the way.”

*And for how long can you remember it?

*How fast can you calculate this:

23 + 45 x 25 – 105 ÷ 15 = ?

= 1141

*Or this

392 x 432 = ? = 2 812 329

Computer calculation VS Human calculation

*How fast can you calculate this:

Kasparov VS Deep Blue

Do you think that computer is

smarter than human?

Computer cannot memorise or remember anything after being

turned off. Computer save data by writing it in storage (i/o device),

not memory.

Storage

Memory

Computer or calculator can calculate quickly because it

process all the numbers in binary using arithmetic and logic unit

Artificial Intelligence is a method to put human knowledge into computer

In some Sci-fi movies you might find artificial intelligence took control of the world. Do you think it’s

possible?

Computer is a machine

*Just like people can go faster with a car or motorcycle, people can do a lot of things easier using a computer. It means…

Computer is machine

using semiconductors

to manipulate electricity
