Description: The term ‘redundant’ refers to memory or resources that are not strictly necessary for the current operations of a system but are maintained as a backup or to ensure service continuity. In the context of memory management in operating systems, redundancy may involve the existence of copies of data or processes that, although not actively used, can be crucial in case of failures or errors. This strategy of maintaining redundant resources is fundamental to increasing the resilience and availability of systems, allowing them to quickly recover from unexpected failures. In many computing environments, redundancy can be used to ensure that systems and applications have access to additional resources in case one fails. In distributed systems, redundancy manifests in how data and operations are replicated across multiple nodes, ensuring that information is available and reliable, even if some nodes fail. Redundancy, therefore, is a key concept in the architecture of modern systems, where data availability and integrity are essential for the effective functioning of applications and services.
