What is an 8085 interrupt?
There are 2 types interrupts in 8085 such as: 1)hardware interrupt 2)software interrupt
How 8086 responds to an interrupt?
When the 8086 microprocessor receives an interrupt signal, it completes the execution of the current instruction and saves the address of the next instruction onto the stack. It then determines the appropriate interrupt vector from the Interrupt Vector Table (IVT) based on the interrupt type. The processor then transfers control to the interrupt service routine (ISR) associated with that interrupt. After the ISR has executed, the 8086 retrieves the saved address from the stack and resumes execution from where it was interrupted.
How are multiple interrupts dealt with?
There are 2 approaches to handle this situation,1.Disable interrupts while an interrupt is being processingin this approach, when the processor is being processing an interrupt, the processor ignores any new interrupt signal and these new signals have to wait in a queue and processor will check after the currently processing interrupt is finished.2. Defining priorities for interruptsin this case, each interrupt has a priority value. When the processor is being executing an interrupt, another interrupt can interrupt and gain the processor if the second interrupt has a higher priority than first oneSource- William Stallings, operating systems Sorry, the word you are looking for is not in the Database
What part of the ozone cycle do CFC interrupt?
The CFC's interrupt the creation part. There are 2 parts namely creation and depletion.
Traditional IBM mainframes recognize different interrupt types?
Yes, from first versions of the IBM 360 architecture there are different interrupt types that put the system into Supervisor mode and invoke the operating system to analyze the interrupt type
Which type of interrupt can not be masked by software?
The TRAP interrupt can not be masked by software, unless there is hardware in place to allow that, perhaps by anding an output bit with the TRAP request line.
What part of speech is interrupt?
Interrupt is a verb.

What is the use of interrupt vector?
An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.

HOW IS SOFTWARE INTERRUPT INITIATED?
Interrupt signals initiated by programs are called software interrupts. A software interrupt is also called a trap or anexception. A signal informing a program that an event has occurred. When a program receives an interrupt signal, it takes a specified action (which can be to ignore the signal). Interrupt signals can cause a program to suspend itself temporarily to service the interrupt. Interrupt signals can come from a variety of sources. For example, every keystroke generates an interrupt signal. Interrupts can also be generated by other devices, such as a printer , to indicate that some event has occurred. PCs support 256 types of software interrupts and 15 hardware interrupts. Each type of software interrupt is associated with an interrupt handler -- a routine that takes control when the interrupt occurs. For example, when you press a key on your keyboard, this triggers a specific interrupt handler. The complete list of interrupts and associated interrupt handlers is stored in a table called the interrupt vector table , which resides in the first 1 K of addressable memory.
What is the auto vectored interrupt?
An auto vectored interrupt is a type of interrupt handling mechanism in computer systems where the interrupting device can provide an automatic vector that points to the appropriate service routine. Rather than requiring the CPU to determine the address of the interrupt service routine (ISR) manually, the hardware generates a specific vector number based on the interrupt source. This allows for faster response times and simplifies the interrupt handling process, as the CPU can directly use the provided vector to locate the ISR. Auto vectored interrupts are commonly used in microcontrollers and embedded systems for efficient interrupt management.
