Internet Concepts: Understanding Web Technologies

1. A university research team in City A needs to collaborate with scientists in City B on a classified defense project. They require a network that remains operational even if a portion is physically destroyed. Which historical network model directly addresses this requirement, and what year did it become functional?

ARPANET, 1969

ARPANET, 1975

Internet backbone, 1969

WWW, 1991

ARPANET, developed in 1969, was the first packet-switching network and laid the groundwork for the modern Internet. Its design prioritized resilience and redundancy, allowing communication to continue even if parts of the network were damaged or destroyed. This decentralized structure was crucial for military and defense applications, making it suitable for classified projects requiring reliability in adverse conditions. The ability to maintain connectivity despite physical disruptions directly addresses the needs of the university research team in their collaboration with scientists in another city.

2. A rural business owner wants high-speed internet but has no access to cable TV infrastructure or telephone DSL lines. However, they have a clear line of sight to a nearby tower. Which connection type is most appropriate, and how does it transmit data?

Satellite internet — via a dish communicating with an orbiting satellite

Fixed wireless — via a dish-shaped antenna communicating with a tower using radio signals

Wi-Fi hotspot — via radio signals from a nearby public location

Dial-up access — via standard telephone lines using analog signals

Fixed wireless is the most appropriate connection type for the rural business owner due to the clear line of sight to a nearby tower. This technology uses a dish-shaped antenna to establish a direct link with the tower, transmitting data through radio signals. Unlike satellite internet, which relies on orbiting satellites and can introduce latency, fixed wireless offers lower latency and higher speeds, making it a suitable choice for areas lacking traditional cable or DSL infrastructure.

3. A student types 'https://www.nps.gov' into a browser and a web page loads. Identify the role of each component in this process: the URL, the web browser, and the web server.

URL identifies the page address; browser retrieves and displays the page; web server delivers the requested page

URL encrypts the request; browser stores the page locally; web server indexes the content

URL identifies the ISP; browser translates IP addresses; web server hosts the domain name

URL is the IP address; browser is the access provider; web server is the backbone carrier

In this process, the URL serves as the specific address that points to a particular web page on the internet, enabling the browser to locate it. The web browser acts as an interface that retrieves the requested page from the web server and renders it for the user to view. The web server is responsible for storing the web page's content and delivering it back to the browser upon request, ensuring that users can access the information they seek. Each component plays a crucial role in facilitating seamless web navigation.

4. A company publishes short employee updates of 150 characters each on an internal platform, while a separate team maintains a journal-style site where only the original author can post entries that users cannot modify. Which web site types match each platform respectively?

Wiki and Blog

Microblog and Blog

Blog and Wiki

Portal and Microblog

The internal platform for short employee updates aligns with a microblog, as it allows for brief, frequent posts limited to 150 characters. In contrast, the journal-style site, where only the original author can post and users cannot modify entries, fits the definition of a blog. Blogs typically feature longer, more detailed entries and maintain a single-author format, distinguishing them from wikis, which allow collaborative editing.

5. An e-commerce startup sells handmade goods directly to individual customers through its website. A separate platform allows customers to sell used items to each other. Classify each business model using the correct e-commerce type.

Both are B2C e-commerce

First is B2B; second is C2C

First is B2C; second is C2C

First is C2C; second is B2B

The first business model involves selling handmade goods directly to consumers, which characterizes a Business-to-Consumer (B2C) model. This is where businesses sell products or services directly to individual customers. The second model allows customers to sell used items to each other, fitting the Consumer-to-Consumer (C2C) classification, as it involves transactions between individual consumers without a direct business intermediary. Thus, the classification accurately reflects the nature of each e-commerce model.

6. A web developer is building a site that allows any registered user to add, edit, or delete content collaboratively, and all recent edits are logged for accuracy review. A colleague argues this is the same as a blog. Is the colleague correct, and what is the key distinction?

Correct — both allow public modification of all posts

Incorrect — a blog allows full content editing, while a wiki only allows additions

Correct — both are collaborative and open to public editing

A wiki and a blog serve different purposes in content management. A wiki is designed for collaborative editing, enabling registered users to add, edit, or delete content, fostering a community-driven approach. In contrast, a blog typically allows only the original author or designated contributors to modify posts, maintaining a more controlled content structure. Thus, while both can feature user-generated content, the key distinction lies in the level of user interaction and modification rights, with wikis promoting collaborative editing and blogs focusing on individual contributions.

7. A media company wants users to begin listening to a live concert broadcast immediately without waiting for the entire audio file to download. Which technology enables this, and what additional software would a user need if their operating system player does not support the file format?

Podcasting; the user needs to subscribe via RSS feed

Streaming; the user needs to download a compatible player such as iTunes or RealPlayer

FTP uploading; the user needs a VoIP router

Streaming; the user needs to install a newsreader application

Streaming technology allows users to access audio content in real-time without waiting for the entire file to download, making it ideal for live broadcasts like concerts. To enjoy this content, users may need a compatible media player, such as iTunes or RealPlayer, especially if their default operating system player does not support the specific audio format being streamed. This ensures that they can seamlessly listen to the broadcast as it happens.

8. A systems administrator is deploying a newly created company website. Arrange the following web publishing steps in the correct sequential order: (1) Maintain the web site, (2) Deploy the web site, (3) Plan the web site, (4) Create the web site, (5) Analyze and design the web site.

3 → 5 → 4 → 2 → 1

5 → 3 → 4 → 2 → 1

3 → 4 → 5 → 1 → 2

1 → 3 → 5 → 4 → 2

The sequence begins with planning the website (3), which outlines the objectives and requirements. Next, the design phase (5) translates the plan into a structured layout. Following this, the actual creation of the website (4) occurs, where the content and functionality are developed. After the website is completed, it is deployed (2) to make it accessible to users. Finally, ongoing maintenance (1) ensures the website remains functional and updated over time. This logical progression ensures a comprehensive approach to web publishing.
