A URL, or Uniform Resource Locator, is the address of a document or "page" on the World Wide Web. It is used to locate and access resources such as websites, webpages, files, and images on the internet. URLs consist of different components, including the protocol (such as HTTP or HTTPS), the domain name, and the specific path to the resource. By entering a URL into a web browser, users can navigate to and view the desired webpage or document.

Google is a search engine that allows users to search for information on the internet. It indexes web pages and provides relevant search results based on the user's query. Macromedia Flash is a multimedia software, Netscape is a web browser, and Librarians' Index to the Internet is a directory of internet resources. Therefore, Google is the correct answer as it is the only option that functions as a search engine.

The Internet allows users to exchange information with friends and colleagues, access various media elements such as pictures, sounds, and video clips, find diverse perspectives on global issues, and post and respond to inquiries on a variety of subjects.

An IP address is a unique number assigned to each computer on the Internet. It serves as an identifier for the computer, allowing it to send and receive data over the network. An IP address consists of a series of numbers separated by periods, such as 192.168.0.1. This address is used to locate and communicate with the specific computer on the Internet.

The World Wide Web Consortium (W3C) is responsible for making and maintaining the Web standards. W3C is an international community that develops open standards to ensure the long-term growth of the Web. It consists of various organizations, individuals, and stakeholders who collaborate to create and update standards for web technologies like HTML, CSS, and JavaScript. Microsoft and Netscape are software companies that have contributed to the development of web technologies, but they are not solely responsible for making the Web standards.

Encryption is the correct answer because it refers to the security measure that hides the identity of sensitive information sent across Web servers. Encryption involves converting the data into an unreadable format using algorithms, making it difficult for unauthorized individuals to access or understand the information. This ensures the confidentiality and integrity of the data during transmission, protecting it from potential threats or attacks.

A script is a piece of computer code that is designed to perform a specific task or set of tasks. It is not an operating system or a language to display web pages. Instead, it is a set of instructions that can be executed by a computer or a web browser to achieve a desired outcome. Scripts are commonly used in web development to add interactivity, automate processes, and enhance the functionality of websites.

SQL Server or Oracle are both viable options for high traffic database-driven web sites. Both databases have robust features and can handle large amounts of data and high levels of traffic. The choice between SQL Server and Oracle ultimately depends on specific requirements, preferences, and budget constraints. Therefore, it is true that SQL Server or Oracle can be used for high traffic database-driven web sites.

Active Server Pages (ASP) is indeed a server-side scripting technology developed by Microsoft. It allows web developers to create dynamic web pages by embedding server-side scripts within HTML. These scripts are executed on the server before the page is sent to the user's browser, allowing for the generation of dynamic content. ASP is commonly used with Microsoft's Internet Information Services (IIS) web server and is widely supported on Windows-based servers.

HTML stands for Hyper Text Markup Language. It is a standard markup language used for creating web pages and applications. HTML uses markup tags to define the structure and layout of a web document, including headings, paragraphs, links, images, and other elements. The term "hyper text" refers to the ability to link different web pages together through hyperlinks. HTML is the foundation of the World Wide Web and is essential for creating and displaying content on websites.

TCP/IP is a fundamental protocol suite that allows devices to communicate over the internet. It provides a set of rules and procedures for establishing and maintaining network connections, ensuring reliable data transmission. Without TCP/IP, devices would not be able to communicate effectively, making it impossible to access and use the internet. Therefore, TCP/IP is indeed required for using the internet, making the given answer "False" correct.

XHTML (Extensible Hypertext Markup Language) is indeed a web standard. It is a stricter and cleaner version of HTML (Hypertext Markup Language) that follows XML (eXtensible Markup Language) rules. XHTML was developed to ensure compatibility with XML-based systems and to promote interoperability among different web browsers and devices. It provides a standardized structure for web pages, making it easier for developers to create and maintain websites. Therefore, the statement "XHTML is a Web standard" is true.

SQL stands for Structured Query Language. It is a programming language used for managing relational databases. SQL allows users to create, manipulate, and retrieve data from databases. It is widely used in the field of database management and is considered the standard language for interacting with relational databases.

to create a private network within the organization. It allows employees to access and share information, documents, and resources securely within the company. Unlike the internet, which is a public network accessible to anyone, an intranet is restricted to authorized users within the organization. It is often protected by a firewall to ensure the security and privacy of the company's data.

An HTML tag is a piece of code, or a small bit of standardized text, that tells a Web browser how to display a specific part of a Web page's text. Tags appear as letters or words in between a "" (greater-than sign).

In XHTML, all elements must be closed. This means that every opening tag must have a corresponding closing tag. Failure to close elements properly can result in errors and make the XHTML document invalid. Closing tags are necessary to clearly define the start and end of elements and ensure proper nesting. By closing elements, it helps maintain the structure and integrity of the document, allowing it to be correctly interpreted and displayed by web browsers.

This is not correct XHTML because the tags are not properly closed. The opening and closing tags for each element should be present, but in this case, the closing tags are missing for the "Coffee" and "Tea" elements. Additionally, the line breaks should be indicated with the "
" tag instead of using "".

An XHTML document must include a doctype declaration to specify the version of XHTML being used. It must also have an opening and closing html tag to enclose the entire document. The head element is used to contain meta information about the document, while the body element contains the actual content. Finally, the title element is used to define the title of the document, which is displayed in the browser's title bar or tab. Therefore, all of these elements are mandatory in an XHTML document.

The correct answer is the U.S. Department of Defense. The Internet was initially developed by the U.S. Department of Defense in the 1960s. It was created as a way to connect computers and share information between different military organizations. The project, known as ARPANET, laid the foundation for what would eventually become the modern Internet.

The Meta Description tag is weighted the highest as far as the Google algorithm is concerned. This tag provides a brief summary of the webpage's content and is often displayed in search engine results. Google considers the Meta Description tag as an important factor in determining the relevance and quality of a webpage, as it helps users understand what the page is about before clicking on it. Therefore, optimizing the Meta Description tag with relevant keywords and compelling descriptions can improve a webpage's visibility and click-through rate in search results.

A machine that contacts a server for information is referred to as a client. A client is a computer or device that requests services or resources from a server, such as accessing webpages, sending emails, or downloading files. The client initiates the communication with the server and sends requests for data or services, which the server then provides in response. The client-server model is a fundamental concept in computer networking, where the client is the user-facing device or software, and the server is the central system that stores and processes data.

All XHTML tags and attributes must be in lower case because XHTML is case-sensitive. This means that using uppercase letters for tags and attributes can lead to errors and the document may not be rendered correctly by the browser. To ensure compliance with XHTML standards, it is necessary to use lowercase letters for all tags and attributes.

XHTML stands for EXtensible HyperText Markup Language. It is a markup language that is used to structure and format content on the internet. The "extensible" part of the name refers to the ability to customize and extend the language to meet specific needs. XHTML is a stricter and cleaner version of HTML, and it combines the best features of HTML and XML. It is widely used for creating web pages that are compatible with different browsers and devices.

Server machines use ports to designate each of their services. Ports are virtual communication endpoints that allow different services to run simultaneously on a server. Each service is assigned a specific port number, which enables the server to differentiate between different services and direct incoming network traffic accordingly. By using ports, server machines can efficiently manage and organize the various services they provide to clients.

The statement is false because XML and HTML will not be replaced by XHTML. XHTML is a combination of XML and HTML, which is designed to be more strict and well-formed than HTML. It is an extension of HTML and follows the same syntax rules as XML. However, HTML and XML will still continue to exist as separate markup languages alongside XHTML.

MySQL is not typically used for high-cost database access. It is a popular open-source relational database management system that is known for its simplicity and ease of use. While it can handle large databases and high traffic, it may not be the best choice for extremely high-cost database access scenarios where performance and scalability are critical. Other database systems like Oracle or Microsoft SQL Server are often preferred for such cases. Therefore, the correct answer is False.

The statement is true because XHTML is an extended version of HTML that follows stricter rules and syntax. XHTML is designed to be more compatible with XML, making it easier for web developers to create well-formed and structured web pages. Therefore, it is correct to say that HTML will be replaced by XHTML.

The correct HTML tag for the largest heading is the

tag. This tag is used to define the main heading on a webpage and is typically displayed in the largest font size. It is important to use heading tags in a hierarchical order, with

being the highest level heading and

being the lowest level heading.

Subject directories are the best search tool for finding websites that have been handpicked and recommended by someone else. Unlike search engines or meta-search engines, subject directories are curated by human editors who review and categorize websites based on their content and quality. This ensures that the websites listed in subject directories are reliable and relevant to the chosen topic. Discussion groups, on the other hand, are platforms for users to engage in conversations and may not necessarily provide handpicked and recommended websites.

c. is the best option because it has the relevant keywords and if you keep the percentages in the range 5-8 for each of the keywords, it is likely to get incredible results. a. is not advisable because you risk a penalty for keyword stuffing. b. would be the right choice for a pets site for children, while in d. you miss a major keyword – “breeds” – and substitute it with a more general one - “animals”. Of course, you can optimize for more than 4 keywords, so the alternatives here are just samples but in any case you can't optimize for an unlimited amount of keywords, so you always need to make choices.
