Question 1

Platform neutrality was a critical factor in the rapid spread and widespread acceptance of the Web.

Accepted Answer

Platform neutrality, which allows content to be accessed from any device or operating system, was a key factor in the success of the Web as it made it accessible to a wider audience. This is in contrast to proprietary systems that only work on specific devices or platforms.

Question 2

The rejected e-mails in a white list spam filter are deleted.

Accepted Answer

The purpose of a white list spam filter is to allow only approved e-mails to reach the inbox, while rejecting all others. Rejected e-mails are not deleted, but instead are either bounced back to the sender or redirected to a spam folder.

Question 3

Software applications that generate information are located in the first tier of n-tier architectures.

Accepted Answer

In n-tier architectures, the first tier is typically the presentation layer, which is responsible for interacting with the user, not generating information. Information generation and business logic are usually handled in the middle tiers.

Question 4

When people use Web browser software to become part of the Web, their computers become Web client computers on a worldwide client/server network.

Accepted Answer

Web browser software allows users to access the World Wide Web, which is a client/server network. When someone uses a browser to access a website, their computer becomes a client computer and communicates with a server computer that hosts the website.

Question 5

Very small companies can run Web sites on desktop PCs.

Accepted Answer

It is possible for very small companies to run their Web sites on desktop PCs, especially if their traffic is low and hardware requirements are minimal. However, as the company grows and traffic increases, it is recommended to invest in dedicated Web servers to ensure better performance and security.

Question 6

Linux is a closed-source operating system software.

Accepted Answer

Linux is an open-source operating system software, which means that the source code is available for anyone to view, modify and distribute.

Question 7

The entity body of a response message returns the HTML page requested by the client machine.

Accepted Answer

The entity body of a response message can contain different types of data, depending on the type of request and response. It can be HTML, JSON, XML, images, video, audio, etc. It is not always an HTML page.

Question 8

A black list spam filter cannot be implemented at the individual level.

Accepted Answer

A black list spam filter can be implemented at the individual level. These filters are often used by email providers and can also be installed as plugins in email clients used by individuals.

Question 9

The basic Web client/server model is a three-tier model.

Accepted Answer

The basic Web client/server model is a two-tier model consisting of a client (such as a web browser) and a server (such as a web server). However, more complex Web applications may involve a three-tier model, which includes a middle tier (such as an application server) that provides additional processing and communication between the client and server.

Question 10

The three main elements of a Web server are the hardware, operating system software, and Web server software.

Accepted Answer

The three main elements of a Web server are indeed the hardware (such as the computer or server), the operating system software (such as Windows or Linux), and the Web server software (such as Apache or Nginx). These three components work together to serve web pages to users who access the server through the internet.

Question 11

In dynamic page-generation technologies, server-side scripts and HTML-tagged text are used independently to create the dynamic Web page.

Accepted Answer

In dynamic page-generation technologies, server-side scripts are combined with HTML-tagged text to create the dynamic Web page, not used independently.

Question 12

A single client request always results in dozens or even hundreds of separate server responses to locate and deliver information.

Accepted Answer

A single client request typically results in one server response that contains the requested information, although complex requests may involve multiple interactions, they do not inherently result in dozens or hundreds of separate responses for a single request.

Question 13

The challenge-response content-filtering technique uses a black list as the basis for a confirmation procedure.

Accepted Answer

The challenge-response content-filtering technique uses a white list as the basis for a confirmation procedure. It only allows access to pre-approved content and blocks everything else.

Question 14

Computers that are connected to the Internet and make some of their contents publicly available using the HTTP protocol are called Web servers.

Accepted Answer

This statement is true.

Question 15

A two-tier client/server architecture is sufficient for delivering dynamic content and processing transactions.

Accepted Answer

A two-tier architecture is not sufficient to handle the demands of modern web applications, which require handling large amounts of data and users simultaneously. A multi-tiered approach that includes a front-end web server, application server, and database server is typically required to effectively deliver dynamic content and process transactions.

Question 16

With remote server administration software, a Web site administrator can control a Web site from any Internet-connected computer.

Accepted Answer

Remote server administration software allows for remote control of a Web site from any Internet-connected computer.

Question 17

The computers that perform the server function usually have more memory and larger, faster disk drives than the client computers they serve.

Accepted Answer

Servers need to handle multiple requests from clients and thus require higher processing power, more memory and larger storage capacity than client computers.

Question 18

The two most commonly used Web server programs are Apache HTTP Server and Microsoft Internet Information Server, IIS.

Accepted Answer

Apache HTTP Server and Microsoft Internet Information Server, IIS, are the two most commonly used Web server programs.

Question 19

The Internet connects many different types of computers that are running different types of operating system software.

Accepted Answer

The Internet connects computers running different types of operating system software, including Windows, MacOS, Linux, and others.

Question 20

In client-side scripting, changes are  generated within the browser using software such as JavaScript.

Accepted Answer

Client-side scripting involves using languages such as JavaScript to manipulate the user's web browser and generate changes without requiring data to be sent back to the server.
