What is a trap in an operating system with example?
Trapdoor is a secret undocumented entry point into a program used to grant access without normal methods of access authentication. A trap is a software interrupt, usually the result of an error condition.

What best describes what the mishap probability component is?
the mishap probability component is an estimation that a hazard will result in a mishap
Does a population have characteristics that result from the organization of its component ecosystems?
yes
Why rstn has 6 t state in 8085 microprocessors?
4 T-states as usual and 2 more are required to perform n*8 its result gives the vector address of interrupt service routine(rstn is an software interrupt)
Why were Farzana and Hassan executed?
Farzana and Hassan were executed because they were convicted of committing a serious crime, such as murder, terrorism, or treason, and were sentenced to death as a result of their actions.
What is interrupt in assembly language?
An interrupt (for example, Intel-based opcode 0xCD) causes the CPU to pause its current execution, store the state of the registers on the stack, then process a defined subroutine. When this subroutine completes, the interrupt finishes, the registers are restored from the stack, and the previous execution state resumes. Interrupts come in two basic flavors: hardware and software. A hardware interrupt occurs when a connected piece of hardware raises an IRQ signal. This mechanism tells the CPU that the hardware has information that needs to be processed. This is more efficient than polling for devices that have relatively few inputs or that have a latency that the CPU shouldn't wait for. Keyboards and mice are often interrupt-driven; the CPU only needs to know when something interesting has happened (a key was pressed or the mouse was moved, for example). Hard drives are also interrupt-driven; this allows the hard drive to locate the requested data and then return that data some CPU cycles later without the CPU having to request the status of the operation repeatedly. In contrast, a software interrupt is usually triggered by software as a means of invoking operating system code in a reliable manner. For example, in MS-DOS, a developer would call INT 0x21 in order to invoke typical DOS commands, such as reading or writing a file, obtaining keyboard input, and other basic operations. Most older operating systems running on Intel-compatible processors use software interrupts to provide a way for the program to access system functions. Newer operating systems use new opcodes that circumvent the need for software interrupts, although most platforms still provide this mechanism for legacy software.
Difference between harware interrupt and internal interrupt?
A hardware interrupt is initiated from a hardware event, such as a byte received from a serial port. It is asynchronous to the running program, i.e. it can occur at any time. An internal, or software, interrupt is initiated by the running program, thus it is under the control of the running program. In the 8085, for instance, the RST instructions are software interrupts. Note, however, that external interrupts can initiate a software RST instruction, so the two events can appear to be the same kind of event. The biggest difference is the handling of the interrupt enable (IE) flag. In the hardware interrupt, the IE flag is turned off when processing the interrupt, and it is turned on right before the interrupt service routine executes the final return instruction. The software interrupt, on the other hand, has nothing to do with IE. As a result, the code must be able to tell the difference.
