1. Users' rights regarding the use of content.
2. Restrictions on the number of devices on which the service can be used.

Geo-blocking restricts access to content based on the user's IP address. By identifying the geographical location, providers can block users in certain regions from accessing specific content, thus enforcing licensing agreements.

1. Ensure your workstation is set up to keep your back straight and your arms parallel to the ground when typing.
2. Take regular breaks to stretch and reduce eye strain from screen time.

VOD content is streamed to allow immediate access without consuming significant storage space on devices. It also permits content to be delivered in real-time while incorporating DRM protections against unauthorized distribution.

Lossy compression is typically used for VOD services as it reduces file sizes significantly by removing some data deemed less critical to overall quality.

Lossy compression is suitable for VOD services since it balances quality and storage efficiency, allowing faster streaming without overwhelming network bandwidth.

Users can check for 'https://' in the URL, indicating that the site uses a secure connection.

Encryption protects sensitive user information during transactions, ensuring that data is safeguarded against interception or unauthorized access.

1. The client connects to the server and requests a secure session.
2. The server sends its SSL certificate to prove its identity.
3. A session key is generated for encrypted communication between the client and the server.

Phishing is a common technique where criminals send fraudulent emails that mimic legitimate sources to trick users into providing personal banking information.

Scalability refers to the system's ability to handle an increasing number of users by efficiently expanding its resources and services to meet demand.

1. Load balancing across multiple virtual servers to distribute user requests more evenly.
2. Creating additional virtual instances on-demand to meet spikes in user activity.

Replication is recommended since it ensures that users can access the same data from multiple locations, improving availability and reducing latency.

Regular synchronization of databases ensures that any changes in one database are replicated across others in real-time, maintaining data consistency.

Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems, enabling them to perform tasks typically requiring human intellect.

A chatbot can handle multiple user inquiries simultaneously, providing quick responses and improving customer service efficiency.

1. Humans can offer empathy and understand complex emotional responses better than a chatbot.
2. Real people can answer diverse queries beyond the routine responses a chatbot can provide.

1. Analyzing the cleaned data to identify trends in user preferences, such as which genres are more popular.
2. Making predictions about future content offerings based on historical viewing data.

1. Managing vast amounts of data requires significant storage and processing capabilities.
2. Ensuring data quality and relevance is challenging due to the volume and rapid growth of incoming data.

Personalized content recommendations may limit users' exposure to diverse genres, fostering a narrow view of available content. Users might also feel uncomfortable with privacy concerns regarding data usage.
