In the instruction of 8086, ASSUME CS : CODE, DS : DATA, SS : STACK the ASSUME directive directs to the assembler the _________.

Explanation:

8086 Microprocessor - ASSUME Directive

Definition: In the assembly language programming of the 8086 microprocessor, the ASSUME directive is used to inform the assembler which segments are to be used for the different segment registers. This directive tells the assembler to assume that the specified segment registers are going to be used for the specific types of segments (e.g., code, data, stack) during the assembly of the program.

Purpose: The ASSUME directive does not generate any machine code; instead, it helps the assembler to correctly interpret the program by associating logical segment names with the segment registers. This directive is essential for ensuring that the assembler understands the organization of the memory segments and can correctly resolve references to variables and instructions.

Example: Consider the statement:

ASSUME CS : CODE, DS : DATA, SS : STACK

In this directive:

• CS : CODE - The Code Segment (CS) register is assumed to be associated with the CODE segment.
• DS : DATA - The Data Segment (DS) register is assumed to be associated with the DATA segment.
• SS : STACK - The Stack Segment (SS) register is assumed to be associated with the STACK segment.

Correct Option Analysis:

The correct option is:

Option 1: The ASSUME directive directs the assembler to the name of the stack, code, and data segments.

This option accurately describes the function of the ASSUME directive. The directive tells the assembler the names of the segments that are to be associated with the segment registers. This information is crucial for the assembler to correctly understand the references to different segments in the program and generate the appropriate machine code.
