Status register is also called as ___________
-
Accumulator
-
Stack
-
Counter
-
Flags
The status register in microprocessors is commonly called the 'Flags' register because it contains individual flag bits (zero, carry, overflow, etc.) that indicate the status of arithmetic and logical operations. Accumulator, stack, and counter are different processor components.
To answer this question, you need to understand the concept of a status register.
A status register, also known as a flag register, is a register in a computer processor that contains the current state of certain condition flags. These flags represent the status of various operations performed by the processor.
Let's go through each option to understand why it is correct or incorrect:
Option A) Accumulator - This option is incorrect. The accumulator is a register that stores the intermediate results of arithmetic and logic operations in a processor.
Option B) Stack - This option is incorrect. The stack is a data structure used to store program variables and return addresses in a computer's memory.
Option C) Counter - This option is incorrect. The counter is a register used to count events or perform operations involving counting in a processor.
Option D) Flags - This option is correct. The status register is also called the flags register because it contains flags that represent the status of various conditions or operations in a processor.
The correct answer is D) Flags. This option is correct because the status register is also known as the flags register.
