How you use segment override prefix in 8086?
In the 8086 microprocessor, segment override prefixes are used to specify a segment other than the default segment for memory access. For instance, the CS, DS, SS, or ES prefixes can be used to direct the instruction to fetch data or code from a specific segment. This is particularly useful when accessing data stored in different segments, allowing for more flexible memory management. By placing the appropriate prefix before an instruction, you can override the default segment registers and control where the CPU looks for operands.
Difference between code segment and data segment of an instruction?
In the 8086/8088 microprocessor, the code segment is used to fetch the opcode and any additional instruction bytes that might be part of the instruction, while the data segment is used to fetch and/or store any operand bytes that the instruction requires to be manipulated.This is in the case of no segment override prefix.
What are the different types of segment register?
The code segment (CS) register is used for access to program code. The data segment (DS) register is used for access to data. The extra segment (ES) register is used for access to data during certain string primitive operations. The stack segment (SS) register is used for access to stack data.Any of these implied uses can be overridden with a segment override prefix opcode.
How the Memory Management Unit converts the logical addresses to physical addresses?
In the 8086/8088, the logical address corresponds to a segment register, such as CS (Code Segment), DS (Data Segment), SS (Stack Segment) and ES (Extra Segment). The segment register is selected by context, or it is explicitly selected using a segment override prefix. The segment register is left shifted 4 bits into a 20-bit temporary register. This is the same as multiplying it by 16. Then the logical address is added to that result. The final result is the physical address.

What is segment address?
A segment address is the contents of a segment register, CS, DS, ES, or SS. It is used after effective address generation to provide an offset in physical memory, by multiplying the segment register by 16 and then adding it to the effective address, giving a 20 bit address. This gives you addressability to 65536 segments of 65536 bytes, each separated by 16 bytes. The register used is usually implicit based on use; CS for code, DS for data, ES for certain string operations, and SS for stack. A segment override prefix can be used to select a different segment register.

What are segment?
In the x86 processor architecture, memory addresses are specified in two parts called the segment and the offset. One usually thinks of the segment as specifying the beginning of a block of memory allocated by the system and the offset as an index into it. Segment values are stored in the segment registers. There are four or more segment registers: CS contains the segment of the current instruction (IP is the offset), SS contains the stack segment (SP is the offset), DS is the segment used by default for most data operations, ES (and, in more recent processors, FS and GS) is an extra segment register. Most memory operations accept a segment override prefix that allows use of a segment register other than the default one.

What is default offset register for DATA SEGMENT?
The default offset register for the data segment in x86 architecture is the Data Segment Register (DS). When accessing data in memory, the DS register is used in conjunction with an offset to point to the location of the data within the data segment. This allows the CPU to retrieve data efficiently from memory. If no specific segment override is used, the DS register is assumed for data accesses.
