1. Users' rights regarding content usage and limitations.
2. Conditions for subscription changes and termination.

Geo-blocking restricts access to content based on the user's actual geographic location, determined by their Internet Protocol (IP) address. This mechanism prevents users in specific countries from viewing particular content, which may be subject to licensing agreements.

1. Maintain proper posture while working by sitting straight with your back supported.
2. Ensure your workspace is ergonomically set up to minimize strain, like adjusting chair height and monitor level.

Streaming allows immediate access to content without the need for substantial local storage space, reduces download times, and ensures users can view content without waiting for it to finish downloading.

Lossy compression will likely be used for VOD services to reduce file size while maintaining a reasonable quality for streaming.

Lossy compression is suitable for VOD content as it significantly reduces the file size, allowing faster streaming, which is essential for maintaining a smooth viewing experience, especially in conditions of varied bandwidths.

One way to determine if the payment platform is secure is by checking if the URL starts with 'https://', indicating the use of a secure protocol.

Encryption is needed to safeguard sensitive information, like credit card numbers, during online transactions, ensuring that it cannot be intercepted by cybercriminals.

1. The client initiates a secure session request to the server.
2. The server sends a digital certificate to the client for validation.
3. Upon validation, a session key is generated for secure communication.

Phishing is a common technique where cyber criminals send fraudulent emails that appear to be from legitimate sources, tricking users into providing sensitive information.

Scalability refers to the capacity of the VOD service to adjust and grow efficiently in response to increased user demand, ensuring seamless service provision without a decline in performance.

1. Load balancing, which distributes user requests across multiple servers to optimize resource use.
2. Cloud computing, where resources can be dynamically allocated or increased as needed.

I would recommend the replication approach as it ensures consistent data availability, allowing for better accessibility and reliability of service for users accessing from different locations.

Regular synchronization of databases can be implemented to ensure all instances of the database are updated simultaneously, using either a master-slave replication model or distributed algorithms.

Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, including learning, reasoning, and self-correction.

A significant advantage of using a chatbot is that it allows for 24/7 customer service, providing immediate responses to user queries without needing human intervention.

1. A real person can handle complex queries that require emotional intelligence and understanding.
2. Human representatives can provide a sense of trust and connection that a chatbot may lack.

1. Analyzing the data to identify trends in user preferences can help tailor content offerings, e.g., recognizing that certain age groups prefer specific genres.
2. Utilizing data visualization tools to present findings effectively can assist in making informed decisions for future content strategies.

1. Managing extremely large volumes of data that may exceed storage capacities.
2. Ensuring data privacy and security amidst increasing threats and regulations.

Relying on data analytics to curate content can lead to privacy concerns, as users may feel their information is being misused. Additionally, it may create a filter bubble, where users only see content that aligns with their past behavior, limiting their exposure to diverse perspectives.
