Concurrent Access

Definitions

1. The situation in which multiple threads, tasks, users, or systems access the same resource at the same time. Concurrent access must be managed carefully when the resource is mutable or expensive, otherwise races, contention, and inconsistent results can occur.

   In plain English: Multiple operations accessing the same thing at the same time.

   Example: "The cache corruption only appeared under concurrent access when multiple requests tried to populate the same missing key simultaneously."
