Which term describes a change in circuit state that is not governed by a clock?

• A. Asynchronous
• B. Synchronous
• C. Clocked
• D. Data-type Latch

Answer: (A)

State changes that happen without a clock are called asynchronous. In asynchronous circuits, outputs respond directly to input changes or events, not to a clock edge. This is in contrast to synchronous (clocked) designs, where all updates occur at defined clock transitions, ensuring timing coordination. A latch is a storage element that can be level-sensitive, often used in various timing schemes, but the question’s focus is on clock governance, which is captured by the term asynchronous.
