Which term refers to a memory register with special features; a flip-flop interconnection having an input that enables binary counting?

• A. Register
• B. Latch
• C. Flip-Flop
• D. Counter

Answer: (D)

Counters are memory devices that store a binary value and automatically advance that value with a control input. They are built from multiple flip-flops wired together so that each clock or enable pulse increases the stored binary number by one, producing a true binary counting sequence. The essential feature is that input that triggers counting—usually a clock edge or an enable line—which differentiates a counter from a simple register or a single flip-flop. A register can store data but doesn’t inherently count or advance its value on each event. A latch holds data when its enable is active and is level-sensitive, not designed for reliable binary counting. A flip-flop stores a single bit and toggles on a clock edge, but by itself it doesn’t provide multi-bit counting. When you connect several flip-flops in the right way with a counting input, you get a counter that increments its binary value with each pulse.
