Question 1

Critical Thinking questions (Multiple Choice) You just sent an e-mail message to your co-worker that looks as follows: HI MARY, CAN YOU PLEASE TELL ME WHEN YOU WILL HAVE THE REPORTS COMPLETED FOR ME? Your co-worker was offended by the message. Why?

Accepted Answer

Using all capital letters is considered shouting in the realm of netiquette, which can be perceived as offensive. In this case, the use of all capital letters in the message may have made the co-worker feel as though they were being yelled at, leading to offense.

Question 2

Critical Thinking questions (Multiple Choice) You want to include your boss on a message to your hired freelancer, but do not want the hired freelancer to see that your boss is included on the message. How can you achieve this?

Accepted Answer

Bcc (blind carbon copy) allows you to add a recipient without them being visible to the other recipients. This is the best choice for this situation as it allows you to include your boss on the message without the hired freelancer being aware. Cc (carbon copy) would show both the boss and freelancer the other's involvement in the message. Adding a priority to the message does not affect the visibility of the recipients. Choosing D would defeat the purpose of keeping the boss's involvement in the message hidden.

Question 3

Case Based Critical Thinking Questions Case 1 Marissa is concerned about Internet security for e-commerce. While researching the topic, she has learned about ActiveX controls and Java applets. To identify the creator of an ActiveX control, Marissa should look at the control's ____.

Question 4

Case Based Critical Thinking Questions Case 1 Marissa is concerned about Internet security for e-commerce. While researching the topic, she has learned about ActiveX controls and Java applets. The URL in the browser's Address box contains the domain name of the Web server that your browser contacts. Your browser opens a socket and connects to a similar open socket at the Web server. Next, your browser generates and sends an HTTP message through the socket. The server sends back the requested HTML document through the open sockets. What is the last step?

Accepted Answer

After sending the requested HTML document, the server closes its socket and the browser also closes its socket. This marks the end of the communication between the client (browser) and the server. The other options, such as sending the request to a printer or sending data to other browsers on the network, are not related to the last step of the client-server communication for retrieving HTML documents. And the browser does not need to go back to the server specifically to find images to display, as images are also included in the HTML document and are retrieved together with the document.

Question 5

Critical Thinking questions (Multiple Choice) If a Web page author includes meta keywords such as "free" and "money" even though the term has little to do with the information on the page, in what practice is this person engaging?

Accepted Answer

This is an example of keyword stuffing, which is a practice of including irrelevant or excessive keywords in order to manipulate search engine rankings. This can lead to penalties or lower rankings for the website.

Question 6

Critical Thinking questions (Multiple Choice) If a Web site can gather information that allows a Web server to present ad banners targeted to products you previously purchased at that Web site, it is using ____.

Accepted Answer

Cookies are small pieces of information stored on a user's computer by a website, enabling the website to remember the user and their preferences, and allowing for personalized advertising. Plug-ins, sockets, and style sheets do not perform this function.

Question 7

Case 2 Jessica does a lot of shopping online and has used an online shopping cart many times. Her major questions are is it safe to shop online, and how does e-commerce affect privacy by gathering information? She is justifiably worried about personal information and credit card numbers supplied in the course of an e-commerce transaction. Merchants who market goods and services are eager to get the attention of prospective customers, but they sometimes secretly gather information and also relay it to advertisers or other interested parties. Most shopping carts work because they use ____ to store information about your activities on a Web site.

Accepted Answer

Most shopping carts use cookies to store information about your activities on a Web site. Cookies are small text files that are placed on your computer by a website or online service that you visit. They can be used to collect information about your browsing history, preferences, and login information. While cookies can sometimes be used for nefarious purposes, they are generally harmless and are an essential component of many e-commerce sites. It is important to be vigilant when shopping online, however, and to only use reputable sites that have trustworthy security protocols in place.

B2C (business-to-consumer) e-commerce involves transactions between businesses and individual consumers, which is exactly what is happening when you purchase a ticket from SkyAir's website.

Question 9

A trade-off to the anonymity offered by anonymous ____ is that they tend not to operate at the same speed as your regular browser.

Accepted Answer

The trade-off mentioned in the statement refers to the slower speed of anonymous proxies compared to regular browsers. FTP sites, URLs, and indices do not offer anonymity, so they are not relevant to the statement. Therefore, the best choice is B) proxies.

Question 11

Critical Thinking questions (Multiple Choice) Java applets ____.

Accepted Answer

Java applets are executed within a restricted environment, known as the sandbox, which prohibits them from starting other programs to maintain security. This limitation is designed to prevent potentially harmful actions by untrusted code.

Question 12

Using fake sites and URLs to misdirect users is called ____.

Accepted Answer

Spoofing involves creating fake sites and URLs to trick users into thinking they are accessing a legitimate site or page. Lurking refers to observing online interactions without actively participating, pharming involves redirecting users to fake websites without their knowledge, and anonymizing involves concealing the identity of the user.

Question 13

Case Based Critical Thinking Questions Case 1 Marissa is concerned about Internet security for e-commerce. While researching the topic, she has learned about ActiveX controls and Java applets. Which of the following is NOT true?

Accepted Answer

Java applets run within the browser and are not installed on the computer like traditional applications. They are designed to be contained within the security sandbox of the browser to prevent unauthorized access to the system resources.

Question 14

Critical Thinking questions (Multiple Choice) Melissa has some digital pictures of the last party she and her friends attended and would like to e-mail them to all of the recipients in her address book. As people are worried about viruses, what can she do to assure her recipients of the e-mail attachments that the e-mail is from a reliable source?

Accepted Answer

By explaining all attachments in the body of the message, Melissa can assure her recipients that the email is from a reliable source and that the attachments are safe to open. Simply being polite or using smileys will not provide any assurance regarding the safety of the attachments. Not sending huge attachments may help to avoid technical difficulties, but it does not address the issue of virus concerns.

Question 15

Critical Thinking questions (Multiple Choice) While using your Web browser to search for a Web site, you get the HTTP status code 404 message. What is your computer trying to tell you?

Accepted Answer

The HTTP status code 404 message means that the requested resource does not exist. This can happen if the URL is incorrect or if the resource has been removed from the server. Option A is incorrect because a 301 or 302 status code would indicate that the resource has moved. Option B is also incorrect because it implies that the resource still exists, but is located elsewhere. Option D is incorrect because a 503 status code would indicate that the resource is temporarily unavailable.

Question 16

Critical Thinking questions (Multiple Choice) POP works by ____.

Accepted Answer

POP (Post Office Protocol) is designed to transfer messages from the email server to the user's computer's hard disk, allowing the user to access and manage their emails offline.

Fake sites are a key part of illegitimate ____ schemes.

Accepted Answer

Pharming is a type of online scam where criminals redirect victims to a fake website, which is designed to look legitimate, in order to steal personal information like login credentials or financial information.

Question 19

Case 2 Jessica does a lot of shopping online and has used an online shopping cart many times. Her major questions are is it safe to shop online, and how does e-commerce affect privacy by gathering information? She is justifiably worried about personal information and credit card numbers supplied in the course of an e-commerce transaction. Merchants who market goods and services are eager to get the attention of prospective customers, but they sometimes secretly gather information and also relay it to advertisers or other interested parties. A(n) ____ is designed to track who is reading the Web page or e-mail message.

Accepted Answer

A Web bug, also known as a pixel tag or clear GIF, is a small, invisible image used to track website or email activity. It can be used to gather information about a user's browsing or purchasing behavior, and this information is often shared with advertisers or other third parties. Client-side scripts, server-side scripts, and Java applets can all be used in e-commerce transactions, but they do not specifically track user behavior in the same way as a Web bug.

Question 20

Accepted Answer

Filters are rules or criteria that can be personalized to detect and categorize spam based on certain characteristics, such as keywords or sender information. Creating your own filters can help catch spam that the antispam software may miss. Quick checks, keys, and routes do not refer to specific spam-detection methods.
