SIM is Set Interrupt Mask. Used to mask the hardware interrupts. RIM is Read Interrupt Mask. Used to check whether the interrupt is Masked or not.
FIFO (First In First Out) stack is used in 8086.In this type of Stack the first stored information is retrieved first.
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.

In other words, pay him a sincere compliment that he can believe because it's anchored in the behavior you've just seen.
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.
Maskable interrupts, Non-Maskable interrupts.
An interrupt which can be never be turned off (ie.disabled) is known as Non-Maskable interrupt
Non-Maskable interrupts are used in critical events. Such as Power failure, Emergency, Shut off etc.
RST 7.5, RST6.5, RST5.5 are Maskable interrupts
TRAP mask is in 8085 dear!
Trap is known as Non-Maskable interrupts, which is used in emergency condition.
