π Topic Summary
This activity explores the concept of data recovery through simulation. Data recovery is the process of retrieving lost, damaged, or inaccessible data from storage devices. This activity allows you to understand the principles behind data storage and recovery without using computers, using physical objects to represent data and methods to recover lost information. It helps in understanding how redundancy and backup strategies are crucial for data preservation.

π Part B: Fill in the Blanks
Complete the following paragraph using the words: backup, redundancy, data loss, recovery, storage.
When a system experiences ____, having a recent ____ is crucial. ____, such as RAID configurations, helps prevent data loss in the first place. The process of retrieving the data is called data ____, and it involves accessing the _____ medium where the data is kept.
Answer:
When a system experiences data loss, having a recent backup is crucial. Redundancy, such as RAID configurations, helps prevent data loss in the first place. The process of retrieving the data is called data recovery, and it involves accessing the storage medium where the data is kept.
π€ Part C: Critical Thinking
