Internet and law refer to the intersection of legal principles and the digital world, addressing issues such as privacy, cybersecurity, intellectual property, online contracts, and digital rights. As the internet has become a central part of modern life, legal systems worldwide have had to adapt to regulate online activities, protect users, and ensure fair practices in areas like e-commerce, data protection, and online speech. Challenges in this field include dealing with cross-border jurisdictional issues, the balance between free expression and regulation, and the evolution of laws in response to new technologies like artificial intelligence and blockchain.
