• What Is Computer Science?

12
Computer Science is about problem solving

• Lets solve a problem!
• In computer science we build Algorithms
• a sequence of steps/instructions to solve a
  problem

13
Problem Solving
A farmer has to get a sheep, a carrot and a wolf
over the river to the grassy field. BUT he can
only take one of them with him at a time
14
Problem Solving
BUT if left alone,

• The wolf will eat the sheep
• The sheep will eat the carrot

15
Internet Safety
16
Who Uses the Internet?
Who Uses E-mail and IM?
Who has Internet connection at home?
17
Some Examples

• Purchasing music, movies, and t.v. shows
• Managing money (online banking)
• Ordering food
• Getting directions
• Playing games
• And SO many others

18
Heres the BAD news

• Crime has followed the same trend and gone online
  as well
• Introducing CYBERCRIME

19
Artificial Intelligence (computer bots)vs Humans
How CAPTCHAs weed out the bots
The CAPTCHA reCAPTCHA projects was developed by
computer scientists from the Aladdin Center at
Carnegie Mellon http//www.captcha.net

are made by Computer Scientists
40
Computer Scientists take this...
41
And make this!
42
Can Computer Science...

• Help solve crimes?
• Help athletes perform better?
• Create pieces of art?

43
Can Computer Science...
YES!

• Help solve crimes?
• Help athletes perform better?
• Create pieces of art?

44
Human Computer Interaction
Does your computer ever make you feel like this?
45
Human Computer Interaction
Computer scientists working in human computer
interaction work to make
computers easier to use.
46
Human Computer Interaction
So that hopefully you feel less frustrated when
using your computer
47
What is Programming?

• A computer can only do what it is told to do
• A program is a set of instructions telling a
  machine what to do
• Programming involves learning how to write
  instructions that do specific tasks
• COMPUTER SCIENCE IS SO MUCH MORE!

48

• Lets program Anthony the Robot to make a jelly
  sandwich!
