Pixels are small squares on a computer screen that reflect lights of color. They are the basic units of a digital image or display, representing a single point of color. Each pixel can be individually controlled to display different colors, allowing for the creation of images and videos on a computer screen.

The file extension commonly used for photographs and most images online is "jpg". This format is widely supported and compatible with various devices and platforms. It offers a good balance between image quality and file size, making it ideal for sharing and displaying images on the internet. PSD is a file extension used for Adobe Photoshop documents, while PPT is for Microsoft PowerPoint presentations. GIF is a format mainly used for animated images.

HTML stands for Hypertext Markup Language. It is a standard markup language used for creating web pages and applications. It is the foundation of the World Wide Web and is responsible for structuring and presenting content on websites. HTML uses tags to define the structure and formatting of the content, allowing for the inclusion of text, images, links, and other media. By using HTML, web developers can create interactive and visually appealing web pages that can be viewed and accessed by users across different devices and browsers.

The highlighted words that take you to another part of a website when clicked are called hyperlinks. Hyperlinks are typically underlined or displayed in a different color to indicate that they are clickable. They are used to navigate between different web pages or sections within a website. Navigation buttons and navigation bar refer to elements that help users navigate within a website, but they do not specifically indicate clickable links. Metatags, on the other hand, are snippets of code that provide information about a web page but do not directly relate to clickable links.

A form is the best way to create the object pictured on a web page because forms allow users to input data and interact with the webpage. This object likely requires user input or selection, and a form provides a structured way to collect that information. XML code, Perl script, and DHTML code can all be used in conjunction with a form, but a form itself is the most appropriate choice for creating this object.

The tags

The correct HTML for inserting an image is "". The "IMG" tag is used to insert an image in HTML, and the "SRC" attribute is used to specify the source or location of the image file. In this case, the image file is "yourimage.jpg".

A Uniform Resource Locator (URL) is the unique address for every web page on the internet. It specifies the protocol to be used (such as HTTP or HTTPS), the domain name or IP address of the server, and the specific location or path of the resource. URLs are used to locate and retrieve web pages, files, images, or any other resources available on the internet.

A web browser is a special software that interprets files to display web pages on the screen. It allows users to access and navigate the internet by rendering HTML documents, images, videos, and other multimedia elements. Web browsers provide a user-friendly interface for browsing websites, interacting with web applications, and accessing various online services. They interpret the code of web pages and present the content in a visually appealing and interactive manner, enabling users to browse and interact with the internet effectively.

Every URL on the internet is converted to a number address known as the Internet Protocol (IP). The IP address is a unique identifier assigned to each device connected to a computer network. It allows devices to communicate and send data across the internet. The IP address consists of a series of numbers separated by periods, such as 10.21.1.3. The IP address is essential for routing data packets and ensuring that information reaches the correct destination on the internet.

When you see a tag that begins with

Cloud computing refers to the practice of using remote servers hosted on the internet to store, manage, and process data instead of using local servers or personal computers. It allows users to access and use software applications and files stored on a web server from anywhere with an internet connection. In this case, the correct answer is "Cloud Computing" as it accurately describes the concept of storing software or files on a web server rather than on one's own computer.

To make a website accessible to people on different computers, it needs to be hosted on a web server. A web server is a computer that stores the website's files and delivers them to users when they request it. It acts as a central hub for hosting and serving web pages over the internet. A web proxy, on the other hand, is an intermediary server that retrieves web content on behalf of users, while a web page refers to a single document or page within a website. A web name typically refers to a domain name or URL that identifies a website.

Tables are a system that allows us to organize objects and text orderly on a page. They provide a structured format with rows and columns, making it easier to present information in a clear and organized manner. Tables are commonly used in various contexts such as data representation, scheduling, and comparison charts. They enable efficient organization and presentation of data, enhancing readability and comprehension for the audience.

A hardware device that works as a 'traffic cop' and directs signals to other computers is known as a router. A router is responsible for directing network traffic between different devices on a network. It analyzes the destination address of incoming data packets and determines the most efficient path for the data to reach its destination. Unlike a firewall, which is designed to protect a network from unauthorized access, a router primarily focuses on routing network traffic. A web proxy, on the other hand, is a server that acts as an intermediary between clients and web servers, handling requests on behalf of the clients. A motherboard, while an essential component of a computer, does not perform the specific function of directing signals to other computers.

All of the mentioned file types, including Flash-based SWF files, JPEG images, and GIF images, are accepted by HTML-based pages.

The correct tag to use to make the smallest heading possible is

. Headings in HTML are used to identify the hierarchical structure of a document, with

being the highest level and

being the lowest level. Therefore,

is the correct tag to use for the smallest heading.

The recommended filename for the main web page is "index.htm". This is because "index" is a commonly used default name for the main page of a website. When a visitor enters a website's domain name without specifying a specific page, the server will typically look for a file named "index" to display as the default page. Therefore, using "index.htm" as the filename ensures that the main page is easily accessible and displayed as the default when visitors access the website.

Dreamweaver is the correct answer because it is a popular Adobe software specifically designed for web designing and editing. It provides a user-friendly interface and a wide range of features that make it easy for users to create and edit websites. Dreamweaver offers both visual design tools and a code editor, allowing users to work with HTML, CSS, JavaScript, and other web technologies. It is widely used by professionals in the field of web design and development.

The attribute "direction" is not a code used with FONT tags to change the text. The FONT tag is used to specify the font, size, and color of the text. The "direction" attribute is used to specify the direction of the text, such as left-to-right or right-to-left, but it is not used to change the appearance of the text itself.

Comments in code are not visible in the browser view. They are used to add notes or explanations to the code for developers to understand the purpose or functionality of certain sections of code. They are ignored by the browser when rendering the webpage, so they do not appear in the browser view. This allows developers to include additional information or instructions without affecting the display or functionality of the webpage.

A drop-down box would be the best input type to create when there are 15 options to choose from. This is because a drop-down box allows for a compact and organized display of the options, making it easier for the user to navigate and select their desired option. Compared to radio buttons or checkboxes, which could become cluttered and take up more space on the screen, a drop-down box provides a more streamlined and user-friendly interface. A textarea field, on the other hand, is more suitable for longer text inputs rather than selecting from a list of options.

The given website, http://www.webdesignclass.com, is an example of a domain name. A domain name is a unique address that identifies a website on the internet. In this case, "webdesignclass.com" is the domain name of the website.

Tiling is the process of repeating an image to fill the background dimensions of a web page. It involves creating a seamless pattern by duplicating and arranging the image in a grid-like fashion. This technique is commonly used to create visually appealing and cohesive backgrounds for websites. The other options, such as repeated, matrixing, and duplicating, do not accurately describe the specific process of repeating an image to fill the background dimensions.

Checkboxes would allow a user to select several options from a list of possibilities. Unlike radio buttons, which only allow for a single selection, checkboxes allow for multiple selections to be made simultaneously. Form fields and drop-down boxes are not specifically designed for selecting multiple options, making checkboxes the most suitable input type for this purpose.

A Cascading Style Sheet (CSS) controls the way your content looks or is presented on a web page. It defines the styles, such as colors, fonts, layout, and positioning, that are applied to HTML elements. The term "cascade" refers to the hierarchical nature of CSS, where styles can be inherited and overridden at different levels. This allows for consistent and organized styling across multiple pages of a website.

The correct answer is "It matches and connects domain names to IP addresses." The Domain Name System (DNS) is responsible for translating domain names (such as www.example.com) into IP addresses (such as 192.168.0.1) that computers can understand. It acts as a directory that allows users to access websites by typing in a domain name instead of the complex numerical IP address. It plays a crucial role in ensuring that users can easily navigate the web by connecting them to the correct IP address associated with a specific domain name.
