Gaming Entertainment? Or training killers?
1.) Moore is reported to have told police, "Life is like a video game. Everybody’s got to die sometime." His brother Steve, a Methodist minister, wants the video game industry to pay: "Why does it have to come to a point to where somebody's life has to be taken before they realize that these games have repercussions to them? Why does it have to be to where my brother's not here anymore," says Steve Strickland. "There's not a day that goes by that I don't think about him."
2.) Doug Lowenstein, who represents the video game industry. "I don't think video games inspire people to commit crimes," says Lowenstein. "If people have a criminal mind, it's not because they're getting their ideas from the video games. There's something much more deeply wrong with the individual. And it's not the game that's the problem."
3.) Violent video games shouldn't be sold to minors and that the states should consider laws that would ban the sale of violent games to those under 17.
4.) They should think twice before the game designers or companies to create such a violent game. They have all the responsibility upon every teenagers behavior since they created the game in the first place and now anyone can have their hands on the game even youngsters.

Social/Ethical Issues of online games:
Privacy and anonymity:-
Usually using online gaming one must create an account that identifies the user. This would become quite an issue if anyone were to get their hands on someone's account information. Usually your account is hacked and even credit card numbers are stored on accounts (for the online billing, so privacy and anonymity are major issues in almost every online aspect.
Equality of Access:-
not everyone is able to access the internet. It may be due to the country, or perhaps even just the area. Limited Internet access may be inaffordable.
People and Machines:-
The relationship between people and machines shift as you rely more on technology for entertainment and pleasure. The increasing popularity of online gaming is increasing human reliance upon machines.
Issues in regarding of online games is that people tend to get sick especially "pulling an all nighter" on Runescape which causes lack of sleep, lack of focus, fatigue and weakness. Also, many "act" like the characters on the game and which may result of violence. These are some issues related to games .

#3. image resolution and pixel depth
#4. A paint program and a photo program both operate on pixels. The are discrete points in an image whether captured from a camera or generated in a paint program. The differences are related to the effects and image processing you employ. In photo processing you often want to correct color, brightness, crop, and clean up an image. In painting you use brushes and other tools to create an image.
#5. CAD software:
-Architectural design: buildings/ bridges
-Floor plans: interior design/ remodeling/ buildings
-Mechanical design: Machinery/ parts/ milling
-Electrical Design: circuit design
3D Modeling:
-Medical: modeling of human organs for learning
-Convey Ideas: can create something that doesn't exist yet, so people have an idea of what it will look like.
-Video game development
-Simulators: flight/ training/ research and development
#6. Since an image is made up of pixels. The mega pixel rating on a camera contains approximately that many millions of pixels. Those quickly add up on your camera's memory card allowing to take pictures in the day or night.

Social consequences of the release of sensitive data stored in databases
If your sensitive data is taken by someone it can be a really big problem. You might lose money, privacy and might even be falsely accused for a crime you never committed. As people have become more aware of identity theft, they are realizing the necessity of the protection of their personal information. It is important to protect our information.
Sensitive data are information that adversely affect a person, the national interest and etc through unauthorized access, or modification. Here's a list of some aspects of Sensitive Data:
1.) Social Security number (SSN)
2.) Credit card number or banking information
3.) Tax information
4.) Credit reports
5.) Anything that can be used to facilitate identity theft (e.g., mother's maiden name)
Sensitive data still exist on discarded or second-hand computer hard disk drives. Most of the people are unaware that sensitive data remain in a hard drive and can be easily recovered. It is very easy to get information about a person. When you visit the web sites, all information is in browser’s history. Even if you delete those temporary Internet files, not all of them are deleted completely. For example word processing creates temporary files when you are working on the programs.
When we delete a file, the file is not actually “deleted.” We all know that the file first goes to the Recycle Bin. But even when we delete files in the Recycle Bin, the files still remain in your computer disk. What happens when you delete a file is that the pointers to the file are removed from the space where it is stored on disk becoming reusable.Even if you format the hard drive, the data are still there. If someone is going to take away your sensitive data, all he/she has to do is to take your hard drive and recover all the data. It is that easy to steal the data. We have to be aware that sensitive data can be easily taken away and we had better take some actions to protect our sensitive and personal information.

7.) It allows you to arrange records in alphabetic or numeric order based on values in one more fields.
8.)In the database design you can add default constraints on columns to avoid data entry errors but usually the front end application that is used to capture the data does most of the validation and disallows saving of that which means the database is left untouched until the correct information is entered.
9.) Record matching compiles profiles by combining information from different database files by looking for a shared unique field.
10.) Yes based on the U.S. Laws Protecting Personal Privacy from Fair Credit Reporting Act to Health Insurance Portability and Accountability act.
11.) Since the computer has all of you information which may be obtained by hackers.

#2. A file manager is a program that enables users to manipulate files on their computers. A database-management system manipulates data in a large collection of files.
#3. All databases have a structure that outlines how data will be stored in the database.
#4. A query is an information request.
#5. For a web application there are certain guidelines that needs to followed:
A. Define the ODBC connection that would associate to your database.
B. You need a server side technology
C. Create a SQL query using the syntax of the server side technology to search your database.
D. Assuming that the search result set is not blank, you would loop through the result set to display the report. The most convenient way would be using a table.
6.) if you write something down on paper it has a better chance of getting lost using management software which makes it easy to find things and you will always no where it is, but storing stuff on a computer is just as insecure as hackers could steal all of your information.

Discussion Questions (Chapter 13) pg. 490
1.) Discuss why you believe e-commerce is important in today's business world. What impacts do you think e-commerce is having on consumers?
E-commerce presents a world of opportunity for doing businesses, reaching global markets and purchasing without leaving the home or office. E-commerce can provide opportunities to improve business processes, just as phones, faxes and mobile communications have in the past.
3.) E-commerce in today's business world because business now revolves around the web. Most people shop on the internet and most businesses make most of their money on the internet. The universities have their own private internet network only accessible to students and staff members. If our school formed a B2B to have a more efficient transaction with other businesses, because they would not be disturbed by other schools or businesses.
6. Privacy is the best way t secure your identity from hackers online. I would pay extra to keep my identity safe because anyone can have access to my account and it would be under my name. Privacy, especially in this world, needs to stay personal because one who steals privacy can do so much with it to their own use.

1.) Why Computer based translations perform translations badly:
The reason is that for instance Google translator translates word for word to another language which may have a different meaning then from the original text. Some words may have more than one meaning and this can require very complex processing.
2.) How a markup language works?
Is a text based language- particularly in web pages.

4.) I believe that everybody should have the right of security on the web especially through email.
5.) I would not mind working in a business where all employees were required to wear active badges. As a matter of fact, in some ways I do. By knowing where all of the employees are located in the building, the employee can be located if they receive an emergency phone call. Also, let's say there is a fire in the building. Security would be able to tell if anyone was trapped inside. I think it's a great idea!
6.) How do the issues raised in the debate over the missile defense system apply to other large software systems? How do you feel about the different issues raised in the debate?
It seems reliably and fair and the issues raised in the debate seems quite fair.

10. Computer security can help protect private information by keeping viruses and other information stealing things out of our computer. But, such virus protection can be carried too far, preventing the computer user from getting any work done.
11. Smart weapons are missiles that use computerized guidance to locate their target. These weapons locate their target without being controlled from a third party. The advantage is that they can be extremely accurate to the target. A risk is that it reduces the amount of time people make to make life and death decisions.

7.) computers have two inherent characteristics that leave them open to attack or operating error: A computer will do exactly what it is programmed to do, including revealing sensitive information. Any computer can do only what it is programmed to do.
8.)One way to reduce the risk of security breaches is to make sure that only authorized personnel have access to computer equipment. Depending on the security system, you might be granted access to a computer based on something you have&endash;a key, an ID card with a photo, or a smart card containing digitally encoded identification
something you know&endash;a password, an ID number, a lock combination, or a piece of personal history
something you do&endash;your signature or your typing speed and error patterns
something about you&endash;a voice print, fingerprints, retinal scans, or other measurements of individual body characteristics, known as biometrics

When Security Threatens Privacy:
*Active badges can simultaneously improve security and threaten privacy by:
*Identifying who enters a door or logs onto a machine
*Finding an employee’s current or earlier location
*Remembering: At the end of the day, an active-badge wearer can get a minute-by-minute printout listing exactly where and with whom he or she has been.
Rules of Safe Computing :
*Share with care.
*Beware of BBS risks.
*Don’t pirate software.
*Disinfect regularly.
*Treat diskettes with care.
*Take your password seriously.
*Lock sensitive data.
*Use backup systems.
*Consider encryption for Internet activities.
*Prepare for the worst.
