3.1 When setting up an office network, some possible essential pieces of equipment could include cables and routers - NSC Information Technology - Question 3 - 2019 - Paper 2

The purpose of a router is to direct data traffic between different networks. It determines the best path for data packets to travel, allowing devices on different networks to communicate effectively. Routers also help manage the data flow, ensuring that information reaches its destination efficiently.

Two benefits of a wireless network include:

1. Flexibility: Wireless networks allow users to connect multiple devices without the need for physical cables, enabling easier relocation of devices.
2. Cost-Effectiveness: Setting up a wireless network can be more affordable as it reduces the need for extensive cabling infrastructure.

An access point is a device that allows wireless devices to connect to a wired network using Wi-Fi or other standards. It acts as a sender and receiver, facilitating communication between devices and the main network. Access points can extend the range of wireless coverage and support multiple users.

Piggybacking refers to the unauthorized use of someone else's internet connection without their permission. This can occur in wireless networks when a neighbor or passersby access the connection without the owner's knowledge, potentially leading to bandwidth depletion and security risks.

Two ways to protect a network from piggybacking include:

1. Changing the Default Password: Replacing the router’s default password with a strong, unique password can prevent unauthorized access.
2. Enabling Network Encryption: Using WPA2 or WPA3 encryption ensures that only users with the correct credentials can connect to the wireless network.

A dynamic website provides a personalized experience for users by generating content based on user preferences and interactions. This adaptability enhances user engagement and delivers tailored information. Additionally, dynamic websites can easily update content, making them more interactive and efficient in meeting user needs.

To ensure your website appears in search listings, implement Search Engine Optimization (SEO) strategies. This includes using relevant keywords, optimizing meta tags, and creating high-quality, valuable content that attracts visitors and encourages backlinks from other reputable sites.

A protocol is a set of rules and conventions for communication between network devices. It defines how data is transmitted, received, and interpreted, ensuring coherent and functional interaction among different systems.

Using the HTTPS protocol is advisable because it provides a secure connection by encrypting data transmitted between the user's browser and the web server. This encryption protects sensitive information from interception and attacks, making it essential for securing transactions and maintaining user trust.

A Personal Area Network (PAN) typically has a very limited range, usually within a few meters. This limitation makes it unsuitable for accessing files stored on a home network from remote locations, as users need a more extensive and reliable connection.

Two reasons why a VPN (Virtual Private Network) is more suitable are:

1. Enhanced Security: A VPN encrypts internet traffic, providing a secure connection even over public networks.
2. Remote Access: VPNs allow users to connect to their home network from any location, enabling access to business files and resources securely.

Rich Internet Applications (RIA) are web applications that offer features and functionalities similar to traditional desktop applications. They typically provide a more interactive user experience by utilizing advanced web technologies like JavaScript, HTML5, and Ajax, enabling rich content and multimedia integration.

An example of a Rich Internet Application is Google Docs, which allows multiple users to collaborate in real time on documents through a web interface.

Two reasons to consider creating an app for your business include:

1. Increased Accessibility: An app allows customers to access your services easily at any time, promoting user engagement and loyalty.
2. Marketing Opportunities: Apps can effectively promote your business through notifications, offers, and integration with social media, driving more user interaction.

Location-based computing refers to services and applications that utilize the geographic location of a device to provide relevant content, context, and functionalities. It enhances user experiences by delivering information tailored to the user's current location.

Technologies used for location-based computing include GPS (Global Positioning System), cell tower triangulation, and Wi-Fi positioning systems. These technologies allow devices to determine their location and interact with services based on geographic data.

A podcast is an audio program or recording that is available for streaming or download on the internet. It can cover various topics and is typically released as a series, allowing users to listen at their convenience.

Streaming refers to the real-time delivery of media content from a server to a receiving device, allowing users to access audio or video without having to download the entire file. For instance, playing a podcast directly from an online platform while the file is temporarily stored on the device.
