Final answer:
RAID Level 1 is commonly referred to as disk mirroring, which offers high data redundancy by duplicating the data onto two separate hard drives to provide continuous system operation and prevent data loss.
Step-by-step explanation:
RAID Level 1 is commonly called disk mirroring. This type of RAID configuration is designed to provide a high level of data redundancy by duplicating the same data on two hard drives simultaneously. In the event that one hard drive fails, the system can continue to operate using the other drive, which contains an exact copy of the data. This redundancy is crucial for preventing data loss and ensuring continuous system operation.
RAID, which stands for Redundant Array of Independent Disks, uses multiple hard drives to achieve various goals such as improved performance, increased data security or both. RAID Level 1 is one of the simpler RAID configurations and is a popular choice for systems where data integrity and reliability are top priorities, like in critical applications or servers.
