The device that assigns timing to sequence operations is the ______.

• A. Timer
• B. Counter
• C. Sensor
• D. Relay

Answer: (A)

A timer is used to assign timing to sequence operations. It provides a controlled delay or interval, so after a set amount of time, the next step in the sequence is triggered. This time-based control is what lets a program or machine step through actions in a precise order.

A counter counts how many events or items have occurred, not how long to wait. A sensor detects a condition or state, signaling when something happens but not setting durations. A relay acts as a switch to turn circuits on or off; it handles power control rather than timing the sequence.
