Virtual worlds are computer-generated environments where users can interact with each other and the surroundings through avatars. These spaces can range from simple 2D platforms to complex 3D simulations, allowing for social interaction, gaming, and creative expression. Popular examples include Second Life and Minecraft, where players can build, explore, and engage in various activities. In virtual worlds, users often create their own content, such as buildings, landscapes, and even entire communities. These environments can be accessed through computers or virtual reality headsets, providing immersive experiences. Virtual worlds are used for entertainment, education, and socializing, making them versatile platforms for diverse activities.
