The technology responsible for translating web pages into multiple languages is called machine translation, often powered by artificial intelligence and natural language processing algorithms. Tools like Google Translate allow users to convert text from one language to another, increasing accessibility to information. This technology enables businesses to reach a global audience and enhances user experience by providing content in the reader's preferred language. However, it’s essential to note that while machine translation is advancing, nuances in language and context may sometimes lead to inaccuracies.
