Description: Persistent storage refers to data storage that retains information even after power is turned off. Unlike volatile storage, such as RAM, which loses its content when disconnected, persistent storage ensures that data remains accessible and recoverable in future sessions. This type of storage is fundamental in various applications, from databases to file systems, and is used in computing environments, servers, and local devices. Key characteristics of persistent storage include durability, data recovery capability, and the ability to perform backups. Additionally, it can be implemented through various technologies, such as hard drives, solid-state drives (SSDs), and cloud storage. Its relevance lies in the need to maintain data integrity over time, which is crucial for businesses and users who rely on information for decision-making and business continuity.
