Search engines use algorithms to scan indexed web pages based on keywords entered by users. They retrieve relevant results by ranking pages according to relevance and importance.
Metadata provides descriptive details about data, making it easier to organise, locate, and retrieve information within databases or search systems.
Cloud storage is a model where data is stored on remote servers accessed via the internet. It allows for scalable storage solutions without the need for physical hardware management by users.
Data redundancy involves duplicating critical data across multiple locations or systems to prevent loss due to hardware failures or corruption. It ensures data availability and reliability.
Indexing creates a structured map of stored data that allows quick lookups instead of scanning entire datasets. It improves speed by enabling direct access paths to required information.
