1. Copyright protections that outline usage rights and restrictions for content accessed through the VOD service.
2. User obligations regarding the number of devices that can be linked to a single subscription, ensuring users understand their limits.

Geo-blocking restricts content access by checking the user's Internet Protocol (IP) address. This address provides information about the user’s geographical location, allowing the service to block or allow content based on regional licensing agreements.

1. Maintain an appropriate posture with back support to prevent strain during prolonged periods of work.
2. Take regular breaks to stretch and reduce muscle fatigue linked to extended periods spent at a workstation.

VOD content is streamed to enhance user experience by enabling immediate access without the need for large storage space. Streaming reduces wait time and allows users to begin watching almost instantly, rather than waiting for a full download.

Lossy compression will likely be used for VOD content because it significantly reduces file sizes while maintaining acceptable quality for streaming.

Lossy compression is most suitable for VOD services as it allows for faster streaming and reduced data usage, which is essential for users with varying internet speeds and bandwidth capacities.

One way to ascertain a secure connection is by checking that the URL begins with 'https://' which indicates that SSL encryption is in use.

Encryption is crucial during online payments to protect sensitive financial information from interception by unauthorized parties, thereby maintaining user trust and safeguarding against fraud.

1. The user's browser requests a secure connection to the server by initiating a handshake.
2. A session key is generated to encrypt the data for that session.
3. The secure connection is established, allowing for encrypted data transfer until the session ends.

Phishing is a common technique where cyber criminals send fraudulent emails resembling legitimate communication to trick users into providing sensitive personal and banking information.

Scalability refers to the ability of the VOD service to adjust and manage increased user demand effectively by expanding resources or capabilities without compromising performance.

1. Utilizing cloud-based virtual servers increases processing power based on demand.
2. Implementing load balancing allows distribution of user traffic efficiently across multiple servers.

I recommend replication/duplication as it ensures data availability across multiple locations, allowing access even when one server fails, thus enhancing reliability for users.

Regular synchronization of databases ensures that all instances of data across various servers are consistently updated, implementing changes in real time or at scheduled intervals to maintain uniformity.

Artificial Intelligence (AI) refers to the ability of a computer or machine to mimic human cognitive functions such as learning, reasoning, and problem-solving.

One advantage of using a chatbot is that it facilitates seamless communication, allowing users to have their queries answered 24/7 without human intervention.

1. Real people can handle complex queries involving emotion and judgement more effectively than chatbots.
2. Users may prefer human interaction to foster trust and rapport, especially in sensitive situations.

1. Data cleaning involves removing outdated preferences from users to maintain current and relevant data; for example, filtering out aged user data that doesn't align with active viewing trends.
2. Analyzing data could involve assessing age demographics to tailor content for the most active user segments on the VOD service.

1. Data storage becomes a challenge as the volume of required data increases, necessitating greater resources to store and manage it efficiently.
2. Analyzing vast amounts of data poses difficulties in deriving meaningful insights, leading to potential misinterpretations.

The practice of using data analytics to provide personalized content may lead to privacy concerns, as users might feel their data is excessively monitored. Additionally, it can foster a restrictive viewing experience by limiting access to diverse content based on algorithmic predictions.
