Answer
Isolation levels define the degree to which the operations in one transaction are isolated from those in other transactions.
Isolation levels help manage concurrent transactions by defining how/when the changes made in one transaction are visible to others. Higher isolation reduces concurrency issues but can slow performance. For instance, setting an isolation level to SERIALIZABLE in a checkout process prevents others from seeing uncommitted changes, avoiding anomalies like dirty reads.
