While I don't have access to specific exam questions or discussions from the last six months, I can provide you with a list of commonly asked questions and topics related to 8086 assembly programming that are often encountered in academic settings or interviews. Here are some example questions:
1. **Basic Instructions**: What are the different types of instructions available in 8086 assembly language? Explain data transfer, arithmetic, logical, and control flow instructions.
2. **Registers**: Describe the purpose of each type of register in the 8086 microprocessor (e.g., general-purpose registers, segment registers, special-purpose registers).
3. **Memory Addressing**: Explain different addressing modes in 8086 assembly language, such as immediate, direct, indirect, register, and indexed addressing modes.
4. **Simple Programs**:
- Write an assembly program to add two numbers.
- Write a program that multiplies two numbers using 8086 assembly.
- Create a program to find the factorial of a number.
5. **Loops and Conditional Statements**: How do you implement loops (e.g., `LOOP`, `JZ`, `JNZ`) and conditional statements in 8086 assembly language?
6. **String Operations**: Explain how string operations are performed in 8086 assembly language. Write a program to reverse a string.
7. **Interrupts**: What are hardware and software interrupts in 8086? Write a simple program to demonstrate the use of software interrupts.
8. **Subroutines**: How do you define and call a subroutine in 8086 assembly language? Provide an example.
9. **Stack Operations**: Explain the stack structure in 8086. Write a program that demonstrates the use of stack operations such as `PUSH`, `POP`, and how to implement recursion.
10. **Macros and Directives**: What are macros in assembly language, and how do they differ from procedures? Explain common assembler directives.
11. **Input and Output**: How do you handle input and output in 8086 assembly language? Provide an example of reading a character from the keyboard.
12. **Error Handling**: How would you handle potential errors in assembly programming? Discuss strategies to ensure robust programs.
13. **Assembly to Machine Code**: Explain the process of converting assembly language programs into machine code.
14. **Debugging**: What techniques and tools can you use to debug 8086 assembly programs? Discuss common errors and how to fix them.
15. **Real-Mode vs Protected Mode**: Explain the differences between real mode and protected mode in the context of 8086 microprocessors.
For specific recent questions or trends, I would recommend checking online forums, academic resources, or studying groups that focus on assembly language or embedded systems. You could also refer to sample exam papers or ask peers in your course or study program.
