2. Invention of WWW (World Wide Web)
( )
• The World Wide Web (commonly
shortened to the Web) is a system of
interlinked hypertext documents
accessed via the Internet. With a Web
browser, a user views Web pages that
b b h
may contain text, images, videos, and
other multimedia and navigates
between them using hyperlinks
hyperlinks.
• The World Wide Web was created in
1989 b B i i h scientist Si Ti
by British i i Sir Tim
Berners‐Lee, working at the European
Tim Berners-Lee
Organization for Nuclear Research
weaves the Web for
Everybody (CERN) in Geneva Switzerland and
Geneva, Switzerland,
released in 1992.

12. Focus on Computer Graphic (Image)
Image Compression
• Lossy Compression: some information are loss,
de‐compression result not same with original
image. Example: JPEG
• Lossless Compression: no information loss, de‐
compression result same with original image.
Example: GIF, TIFF

• PostScript: a standard page-description
page description
language for describing text fonts, illustrations,
and other elements of the printed page
• Used by professional drawing programs such as
Adobe Illustrator and Macromedia FreeHand
• Built into many laser printers and other high‐end
output devices so those devices can understand
and follow PostScript instructions
• PostScript‐based drawing software constructs a

model, by means of computer programs. The model is a
description of three dimensional objects in a strictly
defined language or data structure It would contain
structure.
geometry, viewpoint, texture, lighting, and shading

26. CAD/CAM:
Turning Pictures into Products
• Computer Aided Design (CAD)
software:
– Allows engineers, designers, and
architects to create
– designs on screen for products
ranging from computer
– chips to public buildings
– Can test product prototypes
– Cheaper, faster, and more
accurate than traditional
– design‐by‐hand techniques
Arry Akhmad Arman | School of Electrical Engineering and Informatics ITB | 2008

27. CAM/CIM
/
• Computer‐Aided Manufacturing
p g
(CAM) is the process by which
data related to the product design
are fed into a program that
controls the manufacturing of
parts.
• Computer‐Integrated
Manufacturing (CIM) refers to the
combination of CAD/CAM and is a
major step toward a fully
automated factory.

28. Graphic as Presentation Tools
p
• Remember your goal.
• Remember your audience.
• Outline your ideas.
• Be stingy with words
words.
• Keep it simple.
• Use a consistent design.
• Be smart with art.
h
• Keep each slide focused.
• Tell them what you’re
going to tell them,
then tell them,
then tell them what you told them.
