The days when restaurants could rely exclusively on good food, an enjoyable ambience and word-of-mouth advertising are quickly coming to an end - NSC Information Technology - Question 6 - 2018 - Paper 2

One major threat when using an unsecured hotspot is the potential for data interception. This means that unencrypted data being transmitted can be intercepted by malicious actors, risking personal information.

BitTorrent is a peer-to-peer protocol that allows users to distribute files over the internet by sharing the bandwidth among multiple users, which facilitates quicker downloads of large files.

1. Security Issues: BitTorrent can expose the network to malicious software and unauthorized access.
2. Congestion: The use of BitTorrent can significantly slow down the network due to high bandwidth consumption.

VPN stands for Virtual Private Network.

A VPN allows users to connect securely to a private network over the internet, providing the same security as a local area network (LAN) by encrypting data.

This is a dynamic web page because it is generated in real-time, usually based on user interaction or database queries, which allows for changing information each time it is accessed.

The URL would typically change to include an 'm.' prefix, becoming something like 'http://m.mydinnersite.com/product.asp?id=12345' or use .mobi as the domain extension.

1. Turn off devices when not in use to save energy.
2. Use automatic power-saving features that put the device to sleep after a period of inactivity.

The restaurant could send old electronic equipment to e-cycler recycling programs, which properly recycle electronic waste while protecting the environment.

The technique is called Search Engine Optimization (SEO), which involves optimizing the website to improve its visibility in search engine results.

A DDoS attack involves multiple devices or 'bots' sending excessive requests to the restaurant's website, overwhelming its servers and making the site unavailable to legitimate users.

1. Use strong passwords and regular updates of software to enhance security.
2. Implement firewalls and antivirus solutions to protect against unauthorized access.

A connected app is an application that requires an internet connection to function, allowing access to services and data stored on a remote server, typically enhancing functionality and user engagement.

1. User Experience: Apps usually provide a smoother, more responsive user interface than web pages.
2. Access to Features: Apps can utilize device features, such as GPS and notifications, making them more engaging.

GPS technology is responsible for enabling location-based services that provide personalized content based on the user's geographic location.

1. Customer Engagement: Users who check-in can receive promotions or notifications about new offers.
2. Data Capture: Check-ins provide valuable data on customer preferences and trends that can guide marketing strategies.

A data warehouse serves as a central repository for storing large amounts of data collected from various sources, allowing for efficient data processing and analysis to support business intelligence.

1. Data Analyst: Responsible for interpreting data to identify patterns and trends.
2. Data Scientist: Develops data mining algorithms and performs complex data analysis.

Data mining aims to identify trends and insights within restaurant sales data, enabling management to make informed decisions regarding inventory and marketing strategies based on customer behavior.

1. Accessibility: Users can access the application anywhere there is an internet connection, leading to flexibility.
2. Reduced Resource Needs: It doesn't require local installations on devices, saving storage space.

The desktop package may offer more powerful resources for processing intensive tasks, making it suitable for complex applications where performance is critical.
