In microprocessor status architecture, what do we call the single-bit indicators that are set or cleared to reflect the results of arithmetic or logical operations (e.g., zero, carry, sign)?

Introduction / Context:
Every classic microprocessor, including the Intel 8085A, maintains one-bit indicators reflecting the outcome of ALU operations. These indicators enable conditional branching and efficient program control based on computation outcomes.

Given Data / Assumptions:

• The question asks for the standard term used for one-bit status indicators.
• Typical indicators include zero, carry, sign, parity, and auxiliary carry.
• These bits are grouped in a dedicated status or flag register.

Concept / Approach:
After each arithmetic/logic operation, the ALU updates one or more status bits. Instructions such as JZ (jump if zero) or JC (jump if carry) read these bits to decide the next control flow.

Step-by-Step Solution:

Verification / Alternative check:
Trace an addition such as 0xFF + 0x01: the carry flag sets; a compare that finds equality sets the zero flag. Observing branching behavior confirms the role of flags.

Why Other Options Are Wrong:

• Registers: too general; flags are bits within a specific register.
• Monitors/Decisions: not standard processor vocabulary for status bits.

Common Pitfalls:
Assuming flags are manual inputs; in reality, the ALU hardware sets/clears them automatically unless explicitly manipulated by instructions.

Final Answer:
flags
