An ISR, or Interrupt Service Routine, is a special function in programming that is executed in response to an interrupt signal, allowing the processor to address specific events or conditions, such as hardware signals. An IVT, or Interrupt Vector Table, is a data structure that maps interrupt signals to their corresponding ISRs, enabling the system to quickly locate and execute the appropriate routine when an interrupt occurs. Together, they facilitate efficient event handling in real-time systems.

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.
What are the advantages of building ISR queues?
ISR queues
What is return type of ISR?
void. ISR returns nothing
What does the IVT acronym stand for?
The acronym "IVT" stands for something. It stands for Intermediate Value Theorem. This is a mathematical formula that can be used to solve an equation.
Can you put breakpoint inside ISR?
Yes. We can use breakpoint inside the ISR.
What are three security features commonly found on an ISR?
dmz, NAT,ISR
What are the different steps to invoke ROM bios function?
the following steps are required to invoke a rom-bios function 1)make an interrupt to occur 2)find out the number of the interrupt that has occurred. 3)obtain from IVT,the address of the ISR which services this interrupt. 4)push the current values of CPU register onto the STACK
What do you mean by IVT in 8086?
Interrupt vector table
What is the full form of ISR IN Computer system architecture?
full form of the ISR is interrupt service routine.
What is the benefit for a company to use an ISR router?
An ISR provides the functionality of a switch, router, and firewall in one device
What size engine does the 2013 Bentley Supersports-Convertible-ISR have?
The 2013 Bentley Supersports-Convertible-ISR has a W12 engine.
What is the difference between simple router and isr router?
ISR router will do lot of services compared with normal router. For example terminating VPN Sections, VoIP support, and bridging LAN/WAN cards. Basically ISR routers are modular routers, you can insert WAN T1/E1, SONET, etc cards. - kumar
