What is an interrupt?
interrupt is a disturbance ,and request to do various jobs unusually while executed to be in current process in a system
What is an maskable intErrupt?
interrupts in 8085 are basically classified into two types: 1.Maskable 2.Non maskable maskable interrupts are those which can be delayed.This is done by masking off the interrupts which are not required. Maskable interrupts are:RST 7.5,RST 6.5,RST 5.5 and INTR <decreasing order of priority>
What is the exact difference between interrupt handling and exception handling?
interrupt handling is the process of handling a break or interrupt called by a program where as exception handling is for handling some exceptional conditions that'll occur when a program is running
When devices interrupt occurs how does the processor determine which device issued the interrupt?
It's pretty simple. First, the processor must determine which interrupt occurred. On simple hardware setups, you may already know this just by which interrupt handler was called. On more complex hardware, you may have to read status registers in the interrupt controller. Second, the processor has to look up which devices are capable of asserting that interrupt. On simple hardware, generally there is only one device that can trigger each interrupt and this is determined by the way the device is wired. On more complex devices, this may be determined by software and the processor may have to consult tables that were created during the boot process. Third, the processor must determine which of those devices actually asserted the interrupt (if there's more than one). This is typically done by the driver for each device which generally just asks the device if it triggered an interrupt. Most devices have status registers that either directly tell you whether it caused an interrupt or tell you whether the device needs service which was the point of the interrupt anyway.
What are the requirement of interrupt system in computer?
system itterrupt
What are the main classes of interrupt?
There are six classes of interrupt: *Supervisor Call Interrupts (SVC) *I/O Interrupts *External Interrupts *Restart Interupts *Program Check Interrupt *Machine Check Interrupts
Why specific name of interrupt RST?
Because this mnemonic stands for RESTART (RST).
What is restart?

What does rst in 8085 software interrupt stand for?
RST is simply the opcode chosen to represent the Restart instruction.
What is interrupts and list classes of interrupts in operating system?
An interrupt is an event that alters the sequence in which the processor execute instructions. It is generated by hardware of computer system. Classes of interrupt:- IBM processor has six types of interrupts. * svc interrupt(supervisor call) *input/output interrupts *external interrupts *Restart interrupts *Program check interrupt *Machine check interrupts
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.
What is a sentence with the word interrupt?
"You should not interrupt class," the teacher scolded the boy.
Where is interrupt handler and interrupt vector?
In the 8086/8088, the interrupt vector table is the first 1024 bytes of memory. In the 8085, the interrupt vector table is the first 64 bytes of memory if using the RST form of interrupt, otherwise the interrupt vector is provided by the interrupting device, usually in the form of a CALL instruction. The interrupt handler is wherever the interrupt vector points to.
What is the Prefix of interrupt?
the prefix of interrupt is in
What part of speech is interrupt?
Interrupt is a verb.
What are interrupters?
An interrupt is a hardware-generated change of flow within the system. An interrupt handler deals with the cause of the interrupt. Control is then returned to the interrupted context An interrupt is a hardware-generated change of flow within the system. An interrupt handler deals with the cause of the interrupt. Control is then returned to the interrupted context
What is an 8085 interrupt?
There are 2 types interrupts in 8085 such as: 1)hardware interrupt 2)software interrupt
