👉 In computational science and mathematics, "redundant" refers to a situation where there is a redundant component or element that can be used multiple times in a process or system. In other words, redundancy allows for efficient use of resources by minimizing duplication. For example: 1. A computer has two hard drives: one for primary storage and another for backup. 2. If one drive fails, the computer will not be able to access data from the other drive; redundancy ensures that the secondary drive
