Intel 8086 Interview Questions and Answers will guide us that 8086 or iAPX86 is a 16-bit microprocessor chip designed by Intel, which gave rise to the x86 architecture; development work on the 8086 design started in the spring of 1976 and the chip was introduced to the market in the summer of 1978. So learn more about the Intel 8086 (iAPX86) and get gob preparation with the help of this Intel 8086 Interview Questions with Answers guide

28 8086 Questions and Answers:

1 :: Which technology is used in Bluetooth for avoiding interference?

Frequency hopping is the technology used in Bluetooth.

2 :: Which microprocessor accepts the program written for 8086 without any changes?

8088 is that processor.


3 :: What does EU do?

Basically,8086 is divided into two part. 1.BIU. 2.EU Execution Unit(EU)Fetch the intruction from Queue(memory(6 byte) in BIU.) and execute it.

5 :: Which Segment is used to store interrupt and subroutine return address registers?

Stack Segment in segment register is used to store interrupt and subroutine return address registers

6 :: What is meant by cross-compiler?

A program runs on one machine and executes on another is called as cross-compiler

Programs which compile on One Machine and Execute on Another machine is called cross compiler

7 :: Give examples for Micro controller?

Z80, Intel MSC51 &96, Motorola are the best examples of Microcontroller.

The answer is:If we make the program in one operating system(os-xp) & if we want to execute/runs on another operating sysrem(os-linux),than we can do it by cross-compiler.

8 :: Logic calculations are done in which type of registers?

Accumulator is the register in which Arithmetic and Logic calculations are done.

9 :: What is the position of the Stack Pointer after the POP instruction?

The address line is 02 greater than the earlier value.

10 :: What is the position of the Stack Pointer after the PUSH instruction?

The address line is 02 less than the earlier value.

Decrement by 2.

11 :: Which is the tool used to connect the user and the computer?

Interpreter is the tool used to connect the user and the tool.

12 :: What is internal structure of 8086?

8086 is having 2 different units i.e. BIU(Bus Interface Unit) and EU(Execution Unit), these two units work synchronously.

13 :: Where 8086 mostly used & tell application of 8086?

8086 is used for general purpose like it is used in traffic signals for control purpose .It's also used for small applications like for calculator,etc

scientific calculators & small arithmatic operations

14 :: Why memory width is not 16-bit? In stead of having 8-bit (same as 8085)?

memory size of 8086 is 1MB memory size of 8085 is 64KB 2 ^(adresslines)=size of memory (bytes) so adress lines of 8086 are 20 and 8085 is 16

15 :: What is the difference between 8085 and 8086 in microprocessor?

8086 has a special concept called as memory segmentation.It allows parallel processing, while 8085 does not.

16 :: how many types memory mgt can divided?

they are two types.

they are two types.they are big endian and little endian.

memory is divided into two bank, 1:even bank 2:odd bank.

17 :: What is Piconet?

A collection of devices connected through Bluetooth technology in an ad hoc fashion.

Question What are the three main types of connection used by Bluetooth? Answer Single slave, Master slave, Scatternet

A network of devices connected in an ad hoc fashion using Bluetooth technology. A piconet is formed when at least two devices, such as a portable PC and a cellular phone, connect. A piconet can support up to eight devices.

18 :: What are the three main types of connection used by Bluetooth?

Single slave,
Master slave,
Scatternet .

Master slave

19 :: Give example for Non-Maskable interrupts?

Trap is known as Non-Maskable interrupts, which is used in emergency condition.


20 :: Give examples for Maskable interrupts?

RST 7.5, RST6.5, RST5.5 are Maskable interrupts

TRAP mask is in 8085 dear!
