Which interrupt is also called as trap?
In computing and operating systems, a trap, also known as an exception or a fault, is typically a type of synchronous interrupt caused by an exceptional condition (e.g., breakpoint, division by zero, invalid memory access).
What is the difference between interrupt?
Difference between Interrupt and Exception :
| Interrupt | Exception |
|---|---|
| Being asynchronous, interrupts can occur at any place in the program. | Being synchronous, exceptions occur when there is abnormal event in your program like, divide by zero or illegal memory location. |
What do interrupts and traps have in common?
Traps and interrupts both suspend the execution of the current instruction sequence and temporarily divert control to a dedicated area within the OS kernel. An interrupt is caused by an event external to the current execution. Ex: The completion of an I/O operation or a time-out signal from a clock.
What are the differences between a trap and an interrupt can traps be generated intentionally by a user program if so for what purpose?
A trap is a software-generated interrupt. An interrupt can be used to signal the completion of an I/O to obviate the need for device polling. A trap can be generated intentionally by a user program. It can be used to call operating system routines or to catch arithmetic errors.
What is the difference between trap and exception?
Mostly; the difference between a trap and an exception is like the difference between a car and a vehicle (a trap is one kind of exception, and a car is one type of vehicle; but there are exceptions that aren’t traps and there are vehicles that aren’t cars).
Why are traps synchronous?
A trap may also be generated when a user program makes a definite service request from the OS. Traps are called synchronous events because the execution of the present instructions much more likely causes traps.
What is a person that is a trap?
(slang) The human mouth. (slang, informal, pejorative) A person with male genitalia who can be mistaken for a female; a convincing transvestite or transwoman.
What is trap fault and abort?
Traps. A trap is an exception that is reported at the instruction boundary immediately after the instruction in which the exception was detected. Aborts. An abort is an exception that permits neither precise location of the instruction causing the exception nor restart of the program that caused the exception.
What is trap in Mcq?
Answer:software generated interrupt caused by an error.
What is trap interrupt in 8085?
MicroprocessorMicrocontroller8085. A non-maskable interrupt is a Trap Interrupt which implies that whenever this pin gets activated, the 8085 always gets interrupted even if the state of 8085 is in DI. The input of Trap input is level sensitive and edge sensitive.
