1.

What are the main components of the 8086 architecture?

a)

Operating system, software applications, and firmware

b)

Graphics card, sound card, and network adapter

c)

The main components of the 8086 architecture are the CPU, memory, input/output ports, and buses.

d)

Registers, cache, and hard drive

2.

Explain the function of the segment registers in 8086.

a)

Segment registers are used for input/output operations.

b)

Segment registers manage the power supply to the CPU.

c)

The segment registers in 8086 are used to define the starting addresses of code, data, stack, and extra segments in memory.

d)

Segment registers store the CPU clock speed.

3.

What is the purpose of the instruction pointer in the 8086 microprocessor?

a)

The instruction pointer keeps track of the address of the next instruction to be executed.

b)

The instruction pointer controls the speed of the microprocessor.

c)

The instruction pointer manages memory allocation for the program.

d)

The instruction pointer stores data values for the program.

4.

what is the difference between latch and buffer?

a)
A latch is used for data transmission, while a buffer is for data storage.
b)
A latch operates only in digital circuits, while a buffer can be used in analog circuits.
c)

A latch stores a value based on control signals, while a buffer temporarily holds and strengthen data during transfer.

5.

What is memory segmentation and why is it used in 8086?

a)

Memory segmentation is a method for encrypting data in the 8086 architecture.

b)

Memory segmentation is a technique for compressing data in the 8086.

c)

Memory segmentation is a method of dividing memory into segments for efficient access and management in the 8086 architecture.

d)

Memory segmentation is used to increase the clock speed of the 8086 processor.

6.

How does the 8086 handle data and code segments?

a)

Data and code segments are combined into a single segment in the 8086.

b)

The 8086 uses a flat memory model without segment registers.

c)

The 8086 handles data and code segments using a segmented memory model with segment registers (CS for code, DS for data) to manage memory access.

d)

The 8086 does not support segmented memory and uses only physical addresses.

7.

Describe the different addressing modes available in the 8086 microprocessor.

a)

Virtual and Physical Addressing Modes

b)

Stack, Queue, and Array Modes

c)

Direct Memory Access and Interrupt Modes

d)

The 8086 microprocessor has the following addressing modes: Immediate, Direct, Register, Register Indirect, Based, Indexed, Based Indexed, and Relative Addressing Modes.

8.

The number of bits reserved for address and data in 8086 microprocessor are

a)
16 bits for address and 20 bits for data
b)
32 bits for address and 8 bits for data
c)
24 bits for address and 16 bits for data
d)
20 bits for address and 16 bits for data
9.

what is the difference between maximum and minimum mode in 8086 microprocessor

a)
Minimum mode is for single processor operation; maximum mode is for multi-processor operation.
b)
Minimum mode allows for multi-processor operation; maximum mode is for single processor operation.
c)
Both modes are used for single processor operation only.
d)
Maximum mode is used for low power consumption, while minimum mode is for high performance.
10.

What are the advantages of using assembly language programming for the 8086 microprocessor?

a)

Increased complexity in coding

b)

Limited portability across systems

c)

Slower execution compared to high-level languages

d)

Advantages include direct hardware access, efficient resource use, faster execution, and precise control over operations.
