Question

Which schedule ensures that transactions are executed in the same order as they appear without interleaving?

• A. Serial Schedule
• B. Serializable Schedule
• C. Strict Schedule
• D. Concurrent Schedule

Hint:

Which schedule runs transactions one after another with zero overlap?

Answer 1

The Correct Option is A

Step 1: A serial schedule runs transactions one at a time, from start to finish, with no overlap between them.

Step 2: There is no interleaving of operations, so each transaction completes fully before the next begins.

Step 3: A serializable schedule may interleave but be equivalent to a serial one; a concurrent schedule interleaves; a strict schedule adds recovery rules. Only the serial schedule literally has no interleaving.
