Intel 8086 (iAPX86) Interview Questions And Answers

Frequency hopping is the technology used in Bluetooth.

8088 is that processor.

80186

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.

Trace Flag,
Interrupt Flag,
Direction Flag.

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

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

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.

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

The address line is 02 greater than the earlier value.

The address line is 02 less than the earlier value.

Decrement by 2.

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

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

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

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

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

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.

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.

Single slave,
Master slave,
Scatternet .

Master slave

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

5MHZ

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

TRAP mask is in 8085 dear!

Non-Maskable interrupts are used in critical events. Such as Power failure, Emergency, Shut off etc.

An interrupt which can be never be turned off (ie.disabled) is known as Non-Maskable interrupt

Maskable interrupts, Non-Maskable interrupts.

In 8086 Carry flag, Parity flag, Auxiliary carry flag, Zero flag, Overflow flag, Trace flag, Interrupt flag, Direction flag, and Sign flag.

basically there r two types of interrupti.e.internal and external interrupts.internal interrupts are software inetrrupts which can maskable or nonmaskable where as external interrupts are due to some hardware reset,and are non maskable.

TRAPS: Give a perfect 10, and you'll seem too easy to please. Give anything less than a perfect 10, and he could press you as to where you're being critical, and that road leads downhill for you.
BEST ANSWER: Once again, never be negative. The interviewer will only resent criticism coming from you. This is the time to show your positivism.
However, don't give a numerical rating. Simply praise whatever interview style he's been using.
If he's been tough, say You have been thorough and tough-minded, the very qualities needed to conduct a good interview.
If he's been methodical, say, You have been very methodical and analytical, and I'm sure that approach results in excellent hires for your firm.
In other words, pay him a sincere compliment that he can believe because it's anchored in the behavior you've just seen.
