Also, the information must be secure before published so the wrong ideas aren't implied to people. That way if someone stole that idea it would be even worse because the wrong ideas will be told to the public.

S/E Issues:The need to authenticate information
Information needs to be authenticated so that people won't steal others information and say it to be as their own. That way peoples ideas wont be safe and can make money off others ideas. It is not fair to those who make up the actual idea. Like clothing fashions, A designer might make a new type of clothing and want to make money off of it, but if someone steals that idea and makes money off it, its not fair.

1- Is the Turing test a valid test of intelligence? Why or why not?
2- List several mental task that people do better than computers. List several mental tasks that computers do better than people. Can you find any general characteristics that distinguish the items on the two lists?
2- List several mental task that people do better than computers. List several mental tasks that computers do better than people. Can you find any general characteristics that distinguish the items on the two lists?
- I don't think the turning test is a valid test of intelligence because i do not think the question you have to figure out is valid enough. Having to distinguish the humans questions from the computers questions is just s weird task. A math question would be better or so.
- People are better at doing tasks which involve logic, such as solving an argument and such. Computers are better at solving math problems and getting rid of viruses. As for characteristics, computers have a database of information such as 2+2=4. They will never forget such things so they are better at that. But things such as poems which rely on reading between the lines, and analyzing stuff, humans are better at that.

Ch 15 Review Questions
1. Artificial intelegence is the "moving frontier" because it can lead to high improvements in technology to make life easier for mankind. It can makes computers percieve things and help get more logical answers.
2. The disadvantages to AI is that it shortens peoples attention span and it makes us rely more on technology to do our daily jobs. An alternative might be to onhly rely on technology for those things which are to tedious to do by ones self. Although withb the world we live in today, that might be almost impossible.
4. Early machine translation didn't work so well because it translated works literally. Phrases which weren't ment as they were said, came back in weird translations. As an example, "out of sight, out of mind" because "invisible idiot." Basically, a fail.
5, The reason it is hard for a robot to understand the meaning of "time flies like an arrow" is because the meaning of this isn't a literal one. The meaning is in between the lines and a robot can't think like humans. The quote means that time goes by so fast, that it can be compared to an arrow. Time flies by without us even realizing it.
6. Syntax is the arrangement of a sentence while semantics is the underlying meaning of a word. It is impossible for a sentence to have proper syntax but not semantics. The sentence has to include both to have a proper sentence.
7. A knowledge base contains a system of rules for determining and changing the relationship among facts in a database, while a expert system is designed to replicate the decision-making process of a human expert. It requires a knowledge base so that when a robot is trying to make ethical decisions, it can look to the knowledge base and make sure it isn't going against any morals.
9. What made machine vision so challenging was the fact that it took alot of memmory processing power to make sence of the image.
14. The main difference between a robot and a desktop computer are the input and output peripherals. A computer sends output through printers, while a robot sends output through arm movements and gestures.

If someone discovers a cure for the common cold, should he or she hide it to protect the jobs of allt he people who work in the huge cold-medicine industry?
Identify reasons why so many people react negatively to advances in technology that eliminates some jobs.
Identify reasons why so many people react negatively to advances in technology that eliminates some jobs.
Honestly, i think that by finding the cure to the common cold, people should publicized it. Because with finding the sure, sure some jobs might be eliminated but new jobs will come up. Like the distribution of the cure to different countries. So people should not be upset because curing the common cold will help save lives. Any thing done with a good intention, will genuinely have a good effect
.
The reason people react negatively to advances in technology is
- they're lazy to learn how to use it
- they might loose their jobs that require work, that technology can do itself. By the loss of jobs, people wont be able to pay their bills.

- Do computers increase or decrease efficiency? Explain.
- What are some fears generated by the use of tech/computers in the work place?
- List 3 jobs/skills that have become obsolete in the 21st century and 3 jobs/skills that have taken their place.
- Computers increase our efficiency because they help us save time with our work. They help sort information and can help find what you want faster then going through all the files manually. Also, we can email information in faster ways rather then having to print out a file and hand it to a coworker.
- Some fears generated might be the fear of computers and worries of wrist problems or eye problems and head aches and back aches. People might be fearful because they don't want to ruin their health or they might be intimidated by the new technology. A seemingly old person might not know how to properly function a computer when working and might be to shy to ask someone of a younger age.

Chapter 9 Review Questions
2. It is hard to determine how big the internet is because it is growing so quickly by the minute to measure its growth. Also, the internet doesn't have boundaries and is decentralized. It's inability to have limits make it hard for us to measure exactly how big it can be.
3. TCP/IP's are very important for the functioning of the internet because it allows cross-network communication. Without this, the TCP/IP wouldn't be able to do its job.
4. The type of internet connection you have influences the things you do with the internet becasue depening on the connectio, you can either do more or less things. With a direct connection, computers give quick responces, and have all the files stored on the computer. Where as with dialup connection, the connection is limited.
5. With the client/server model, people can share information and files, but its mainly the server who distributes the files while the client can only look at them. The server has more power in this and both users see the information differently.
6. Email addresses and URL's are similiar becuase they both have, in a way, a domain name. email addresses and URL's both take you to the main website. Email addresses follow the host name while URL's follow the domain name (such as .edu and .com).
9. File compression is important on the internet because you want to be able to send your files easily. By compressing the files, it takes up less space and travels faster.
11. Push technology is used to have information delivered automatically to the clients computer. This is better then standard web page delivery systems, becasue the stadnard system would have to ask a request to send information, where as push technology sends it automatically.
12. By the commercialization of the internet, we are able to do better things like digital chas transactions online and search whatever we like online. There are problems with these methods though. When searching on the internet, inappropriate content might pop up, or hackers can access your bank code. These problems must be put down with passwords and filtering software.

Suppose you have an important message to send to a friend in another city, and you can use the telephone, email, real-time teleconference, fax, or overnight mail service. Discuss the advantages and disadvantages of each. See if you can think of a situation for each of the five options in which that particular option is the most appropriate choice.
1. Phone calling. The advantage for this would be that you can get responces from your friend at that very moment. The disadvantage would be that maybe your friend might not pick up.
2. email. The advantage would be that you can write a message as long as you want when ever you have time. The disadvantage would be waiting for the reply.
3.realtime conferencing. This would be good for relaying the message and being able to talk, the disadvantage would be that if your friend doesnt have video conference then it won't work.
4. Fax: advantage: you can send the message easily but not every one has fax and the message might get lost along the way.
5. mail. advantage: you know that your friend will receive your message and it will be saftly carried. disadvantage: you would have to wait for your mail to reach the person
Each of these option are good but some might be more reliable then others. Not everyone has money to buy real time conferencing or fax machines. This leaves phones, email, and mail. Mail would take to long, while email and phone calls would be wayu easier. With ohone calls you can talk to the person directly, and with emails you can send as big of a message as you want. Emails are better because you can send emails when ever you and your friend have time and they are more convenient.

3/9/11
1. DQ: What have you done this week that directly or indirectly involved a database? How would your week have been different in a world without databases?
This week i used Google to help find ideas for my Theory Of Knowledge essay. Google is a database that i use almost on a daily basis. It has a bunch of data you can find by simple searches in the search box. You can also find a wide arrangement of data from 'how to plant flowers' to 'where to buy a new computer'.
If we did not have databases then the world would be different because there would be no main source to go to for information. There would not be anywhere to store large amounts of information either. We would have to find out a new way to store information easily that would be accessible to.

Chapter 6 Graphs, Digital Media, and Multimedia
1.What is the difference between graphics and digital media, and multimedia?
Graphics refers to pictures and images, digitial media refers electronic media that works on digital codes, and multimedia refers to videos.
-wanted to create an open-ended hypertext system with no boundaries so scientists everywhere can work together
-invented the world wide web
-works at MIT
-heads the world wide web Contortion (W3C)
-paint pixels on the screen with a painting device
-pointer movements are translated into lines on the screen-stores images at 300 dots per or higher
Define Bitmapped graphics.
Pixels: tiny dots of white, blackl, or color that makes images on the screen
-Far more powerful then traditional photo-retouching techniques
--> can distort and combine photos --> can fabricate images so there's no show of evidence of tampering
3. What does digital management software do?
Digital mamagment software sorts out tasks and helps the user do common tasks like editing.
-Memory demans on storage are not as high as for bit-mapped images
-Many drawing tools-line, shape and text tools- are similar to painting tools in bitmapped programs
4. Define object- oriented and vector graphics. Whats the difference?
They're the same thing. they are collections of lines and shapes.
PostScript: a standard page-description language for describing text fonts, illustrations, and other elements of the printed page
- used by professional drawing programs such as adobe illustrator article on adobe illustrator and Macromedia freehand.
Bit-mapped Painting (pixels) gives you these advantages
-lines are cleaner and shapes are smoother
Some programs merge features for both in a single application
-blurs the distinction between types
-offers possiblities for ammiturs and professionals
-borrow from the best
-choose the right tools for the job
-protect your works
5.What is the difference between drawing and painting?
Drawing uses simple tools to make pictures, while painting has much better results.
-can test product prototypes
-cheaper faster, and more accurate
6.whats the difference between CAM and CIM?
CAM is when data is fed into a program that controls the parts of the program, while CIM is a almost completed full factory.
-Computer aided manafacturing: is the process by which data related to the product design are fed into a program that control the manafacturing of parts
-Computer intergrated manufacturating: refers to the combination of CAD CAM and is a major step toward a fully anomated factory.
-creates slideshows directly on computer moniters or LCD projectors, including dtill images, animation, and video clips
-rmbr your audience
-be stingy with words
-outline your ideas
-keep it simple
-use a consistent design
-be smart with art
-keep each slide focused
-tell them what youre going to tell them. then tell them, then tell them what you told
-animation
-desktop video
-audio

-Tweening: instead of drawing each frame be hand, the animator can cfreate key frames and objects and use software to help fill in the gaps
-->a video digitizer can convert analog video signals from a television broadcast or videotape into digital data
-any video digitizers can import signals from televisions, videotapes, video camersa and other sources.
-digital video cameras can capture foootage in digital form
-digital vdieo can be copied, edited, stored. and played back without any loss of quality
-digital video will soon replace analog video for most applicants
7.question what is a video digitizer?
a device that converts videos from tvs to digital data
8.what does nonlinear editing mean?
when you can editi any frame of a video
-video editing software: such as adobe premire makes is easy to eliminate extensive footage, combine clips from multiple takes, splice together scenes, create specific effects and preform a veriety of other activities
-morph: are video clips in which one imafe met

Tim Berners-Lee Weaves the Web for everybody
-born in London in 1955-wanted to create an open-ended hypertext system with no boundaries so scientists everywhere can work together
-invented the world wide web
-works at MIT
-heads the world wide web Contortion (W3C)
Painting: Bitmapped Graphics
Painting software:-paint pixels on the screen with a painting device
-pointer movements are translated into lines on the screen-stores images at 300 dots per or higher
Define Bitmapped graphics.
Pixels: tiny dots of white, blackl, or color that makes images on the screen
Palette of tools mimics real-world painting tools
Bitmapped graphics are pictures that show how the pixels are mapped on the screen
Color depth: the number of bits devoted to each pixel
Resolution: the density of the pixels
2. Define color depth, resolution, and pixels.
Color depth is the ammount of pixels in a image
Resolution is the quality of the pixel.
Pixels are the small dots which make up the picture.
Image Processing: Photographic Editing by computer
-Allows the user to manipulate photographs and other higher resolution images with tools such as Adobe Photoshop-Far more powerful then traditional photo-retouching techniques
--> can distort and combine photos --> can fabricate images so there's no show of evidence of tampering
Focus on computer graphics
-Digital Photo Management software programs such as apple iPhoto and Microsoft PictureIt! simplify and automate common tasks associated with campturing, organizing, editing, and charing digital images3. What does digital management software do?
Digital mamagment software sorts out tasks and helps the user do common tasks like editing.
Drawing: Object
oriented Graphics
-drawing software stores a picture as a collection of lines and shapes called object-oriented or vector graphics-Memory demans on storage are not as high as for bit-mapped images
-Many drawing tools-line, shape and text tools- are similar to painting tools in bitmapped programs
4. Define object- oriented and vector graphics. Whats the difference?
They're the same thing. they are collections of lines and shapes.
PostScript: a standard page-description language for describing text fonts, illustrations, and other elements of the printed page
- used by professional drawing programs such as adobe illustrator article on adobe illustrator and Macromedia freehand.
Bit-mapped Painting (pixels) gives you these advantages
-more control over textures, shading and fine detail
-approximate for screens displays, simulating natural paint media, and embellishing photographs
-approximate for screens displays, simulating natural paint media, and embellishing photographs
Object-oriented drawing gives you these advantages:
-better for creating images-lines are cleaner and shapes are smoother
Ø
Some intergrated programs contain both drawing and painting models
---> allows you to choose the right tool for each jobSome programs merge features for both in a single application
-blurs the distinction between types
-offers possiblities for ammiturs and professionals
Rules of thumb: Creating Smart Art
-Reprogram yourself-borrow from the best
-choose the right tools for the job
-protect your works
5.What is the difference between drawing and painting?
Drawing uses simple tools to make pictures, while painting has much better results.
Computer Aided Design software:
-allows engineers, designers, and architectures to create design on screen for products randging from computer chips to public buildings-can test product prototypes
-cheaper faster, and more accurate
6.whats the difference between CAM and CIM?
CAM is when data is fed into a program that controls the parts of the program, while CIM is a almost completed full factory.
-Computer aided manafacturing: is the process by which data related to the product design are fed into a program that control the manafacturing of parts
-Computer intergrated manufacturating: refers to the combination of CAD CAM and is a major step toward a fully anomated factory.
