What is the function of the interrupt vector in computer systems?
The interrupt vector in computer systems is a table of memory addresses that point to specific routines or functions that handle different types of interrupts. When an interrupt occurs, the processor looks up the corresponding memory address in the interrupt vector to determine which routine to execute. This allows the computer to respond to external events or signals in a timely and organized manner.
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 interrupt operating system and how does it handle interruptions in the execution of tasks?
An interrupt operating system is a type of operating system that can pause the execution of tasks to handle unexpected events or requests. When an interruption occurs, the operating system temporarily stops the current task, saves its state, and then processes the interrupt. Once the interrupt is handled, the operating system resumes the original task from where it left off. This allows the system to efficiently manage multiple tasks and respond to external events in a timely manner.
What can be the requirement of computer system for IGI game?
i just want to know that for installing the iGI game,how much hard disk,ram ,processer is required/
What is interrupt initiated io?
Interrupt-initiated I/O is a method in computer systems where input/output operations are triggered by hardware interrupts rather than being managed by the CPU in a polling manner. When a device is ready for data transfer, it sends an interrupt signal to the CPU, prompting it to pause its current tasks and handle the I/O request. This allows for more efficient CPU utilization, as the CPU can perform other tasks instead of constantly checking the status of I/O devices. Overall, this mechanism enhances system responsiveness and performance.
What is the difference between polling and vector interrupt system?
In a computer, a vectored interrupt is an I/O interrupt that tells the part of the computer that handles I/O interrupts at the hardware level that a request for attention from an I/O device has been received and also identifies the device that sent the request. A vectored interrupt is an alternative to a polled interrupt , which requires that the interrupt handler poll or send a signal to each device in turn in order to find out which one sent the interrupt request.
What is the full form of ISR IN Computer system architecture?
full form of the ISR is interrupt service routine.
What is irq3?
Interrupt Request - IRQ0 through IRQ7 commonly.Interrupts are a commonly used technique for computer multitasking, especially in real-time computing. Such a system is said to be interrupt-driven.An act of interrupting is referred to as an interrupt request (IRQ)
Is operating system interrupt driven?
Yes, an operating system is interrupt driven.
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 virus can interrupt almost any function executed by the computer operating system and alter it for its own malicious purposes?
Resident
What is a NMI error?
It's a Non Maskable Interrupt. It is an interrupt to a computer system that cannot be ignored (can't be masked). For example; when you push the reset button on the PC front panel you are performing an NMI. All services will be interrupted to perform a system boot.
What is interrupt conflicts in computers?
Intrrup conflicts are when one device in a computer takes the interrupt from other device in the os. Intrrup conflicts are when one device in a computer takes the interrupt from other device in the os.
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 irq3 used for?
IRQ Interrupt Request 3 are usually reserved for COM port (1,2,3,4) but can be assigned to anything.Interrupts are a commonly used technique for computer multitasking, especially in real-time computing. Such a system is said to be interrupt-driven.An act of interrupting is referred to as an interrupt request (IRQ
What is predefined interrupt?
A predefined interrupt is a specific type of interrupt in a computer system that is assigned a unique identifier and is associated with a particular event or condition. These interrupts are typically defined by the hardware or system architecture, allowing the processor to handle events like input/output operations, timer expirations, or hardware malfunctions. When such an event occurs, the predefined interrupt signals the processor to pause its current tasks and execute a designated interrupt service routine (ISR) to address the event. This mechanism enhances system responsiveness and efficiency by allowing asynchronous event handling.
What is the difference between polling and vectored interrupt system with example?
i need compare between vectored interrupt system and polling
