Portals are gateways or openings that connect two different locations or dimensions. In science fiction and fantasy, they often allow characters to travel instantaneously between worlds, such as from Earth to a magical realm. These portals can take various forms, including doors, gates, or even swirling energy fields. In technology, the term "portal" refers to a website or platform that serves as a gateway to a variety of resources and services. For example, a web portal might provide access to news, email, and social media, all in one place, making it easier for users to navigate the internet.
