TExES Tech Apps Quiz: Internet Networks And Webmastery!

A WAN is a wide area network that spans a more broad geographical range.

Every computer that is connected to a network, including the internet, is assigned an identification number known as its IP address. This IP address acts as a unique identifier for the computer on the network, allowing it to send and receive data. The IP address is crucial for communication between devices on a network, as it helps in routing data packets to the correct destination.

As opposed to static IP addresses that never change.

thus the abbreviation "http://"

A web server is a specialized computer that is always connected to the internet and is responsible for delivering web pages to host computers that request them. This means that the statement is correct.

Firewalls are essential for keeping out hackers as they act as a barrier between a computer or server and the internet, monitoring and filtering incoming and outgoing network traffic. They can block unauthorized access attempts, prevent malicious software from entering the system, and detect and alert the user about suspicious activities. While antivirus software and spybots are also important for protecting against malware, firewalls specifically focus on preventing unauthorized access and are crucial for network security. Insulators, on the other hand, are not relevant to computer security and do not provide any protection against hackers.

The purpose of having an intranet is to limit access to certain information. An intranet is a private network that is only accessible to authorized individuals within an organization. It allows companies to restrict access to sensitive data, such as confidential documents, internal communications, and proprietary information. By limiting access to certain information, organizations can ensure that only authorized personnel can view and interact with sensitive data, protecting it from unauthorized access and potential security breaches.

The internet can be considered a Wide Area Network (WAN) because it connects multiple local area networks (LANs) across different geographical locations. It allows for the transmission of data over long distances, enabling communication and sharing of resources between computers and devices. The internet uses various networking technologies and protocols to ensure reliable and efficient data transfer, making it a prime example of a WAN.

Encryption is the process of converting data into a form that is unreadable to unauthorized users. It ensures the security and confidentiality of the data by transforming it into nonsense characters. These characters can only be understood and translated back into sensible characters by authorized individuals who possess the decryption key. Encryption is widely used in various applications, such as secure communication, data storage, and online transactions, to protect sensitive information from being accessed or intercepted by unauthorized parties.

To get multiple columns of text on a web page, it is best to use tables. Tables allow for the creation of rows and columns, making it easy to organize and display content in a structured format. By using table elements, developers can specify the number of columns and control the placement of text within each cell. This ensures that the content is displayed in a visually appealing and organized manner, making tables the ideal choice for creating multiple columns on a web page.

To achieve a uniform look on all pages of a website, it is best to use templates. Templates provide a consistent layout and design elements that can be applied to multiple pages. This ensures that the website maintains a cohesive and professional appearance throughout. Using tables or sliced images may not provide the same level of consistency and may result in a disjointed or cluttered look. Random colors also do not guarantee a uniform appearance. Templates, on the other hand, offer a structured and standardized approach to design, making them the ideal choice for achieving a consistent look across all pages of a website.

To ensure that an image on a web page appears the same for all users, it is necessary to use a web-safe color palette. This is because web-safe colors are a set of 216 colors that are supported by all web browsers and operating systems. By using these colors, the image will be displayed consistently across different devices and platforms, ensuring a consistent and reliable viewing experience for all users.

AOL, AT&T, and Earthlink are all examples of ISP's (Internet Service Providers). ISP's are companies that provide internet access to customers, allowing them to connect to the internet and access various online services. These companies typically offer different types of internet connections, such as dial-up, broadband, or wireless, and may also provide additional services like email accounts, web hosting, and virtual private networks (VPNs). AOL, AT&T, and Earthlink are well-known ISP's that have been providing internet services to customers for many years.

Bandwidth refers to the maximum amount of data that can be transmitted over a network in a given period of time. Just like water flowing through a pipe, bandwidth represents the flow of data through a network. Similar to how the size of a pipe determines the amount of water that can pass through it, the bandwidth of a network determines the amount of data that can be transmitted. Therefore, the comparison of bandwidth to water flowing through a pipe is the most appropriate analogy.

Using multiple folders on a webserver to store pages in a website helps in organizing and categorizing the files effectively. By separating the pages into different folders based on their content or purpose, it becomes easier to locate and manage specific files when making updates or modifications to the website. This improves the overall efficiency of managing the website's files and ensures a streamlined workflow for website maintenance.

Web-enabled programs run through browsers with the use of plug-ins. Plug-ins are additional software components that add specific features or functionality to a web browser. They allow the browser to display certain types of content, such as multimedia or interactive elements, that are not natively supported. Plug-ins are installed separately and can be activated or deactivated as needed, providing flexibility and customization options for the user.

FTP (File Transfer Protocol) is the correct answer because it is a protocol specifically designed for uploading and downloading files to and from a server. TCP/IP is a network protocol suite, HTTP is a protocol used for transferring hypertext documents, and ISP (Internet Service Provider) is a company that provides internet access. None of these options are specifically designed for file transfer like FTP.

They can, but they don't have to!

TCP/IP is the internet transfer protocol that sends, receives, and verifies the transmission of chunks of data called packets. Packets are small units of data that are sent over a network. They contain the necessary information for successful transmission, including the source and destination addresses, as well as the actual data being transmitted. By breaking down data into packets, TCP/IP ensures efficient and reliable communication over the internet.

A URL is the named location of a file on a web server. It is a specific address that allows users to access a particular webpage or resource on the internet. It consists of various components such as the protocol (http, https), the domain name (www.example.com), and the specific path or file name (/index.html). By entering a URL into a web browser, users can retrieve the desired file or webpage from the web server where it is hosted.

The correct answer is head & body. In HTML pages, the head section is used to provide metadata about the document such as the title, style sheets, and scripts. The body section contains the main content of the document, including text, images, links, and other elements that are visible to the user.

The given HTML code has three attributes associated with the `` tag. The attributes are `color=green`, `size=4`, and `face="Arial"`.

CSS= Cascading Style Sheets. This defines the styles of elements. The styles can be inline or reside as a separate file on the webserver that the end user never sees.

The common Boolean operators are: AND OR NOT. The "minus" sign is typically translated as NOT.

In a typical network, printers are assigned static IP addresses to ensure they always have the same address. On the other hand, workstations are assigned dynamic IP addresses that are leased or rotated every 30-90 days to allow for flexibility and efficient use of available IP addresses. The server responsible for assigning these dynamic IP addresses to computers is called the DHCP (Dynamic Host Configuration Protocol) server. This server manages the allocation and configuration of IP addresses, subnet masks, default gateways, and other network parameters for devices on the network.

Alt tags with all images should be included to make a web page accessible to students with limited vision. Alt tags, or alternative text, provide a textual description of the image, allowing screen readers to read the description aloud to the user. This ensures that visually impaired students can understand the content and context of the images on the web page. Audio descriptions may also be helpful for students with limited vision, but they are not mentioned as a requirement in the question. High-contrast colors and frames are not directly related to making images accessible for students with limited vision.
