Google’s core function is its search engine, which indexes billions of web pages to deliver the most relevant results based on user queries. When a search is made, Google analyzes hundreds of factors, such as keywords and site quality, to rank pages. The results are then displayed in seconds, providing links to websites, images, videos, and news. Google also works through its wide array of interconnected services. Users can access Gmail for email, Google Drive for cloud storage, and Google Docs for collaborative document editing. Each service is integrated, allowing users to move seamlessly between them for productivity, communication, and entertainment.
