CAS enables atomic updates without locks. Frame the concept in practical terms so you can explain it during interview discussion.
CAS (Compare-And-Swap) allows atomic updates to variables by comparing the current value with an expected value and updating only if they match. This contributes to non-blocking algorithms as it avoids the need for locks, reducing contention and increasing throughput. For instance, in a high-throughput system managing user sessions, CAS can efficiently handle session counter updates without delays caused by locking.
