Why does the president of the US interrupt television programming?
The President does not actually interrupt programming. He makes speeches and the networks decide whether or not to interrupt their programming. Not every speeh is carried by every network.
What is multiprogaming?
Its a form of programming while multitasking
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)
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 interrupt handler service?
They are the ones that reports errors when compiling codes in an programming language.
Is the execution of multiple tasks at one time?
MULTITASKING!! Multitasking Another technique that helps servers use their system resources more efficiently is multitasking, which is the execution of multiple tasks at one time
How you can perform a multitasking in C programming language?
Multi-tasking is supported by the fork and exec subroutines in the C library.
Why windows is multitasking and UNIX is multiprogramming?
Not really a true statement; both Windows and UNIX have multi-tasking and multi-programming capabilities.
Why used interrupts?
An interrupt is a signal from hardware (h/w interrupt) or software (s/w interrupt) to indicate the occurence of an event. It indicates the need of a change in execution. Interrupt handling or servicing of the interrupts depends upon the design of the operating system. A routine which will be called for servicing the interrupt is known as interrupt service routine or ISR and the request for the ISR through an interrupt is known as interrupt request or IRQ. Interrupt is a mechanism used for implementing the multitasking concept. It will use the concept of context switching, for servicing the request.
What is pre-emptive multitasking?
In preemptive multitasking scheduling processes , scheduler can interrupt one running process and and allocate CUP to another process without letting the complete the task of first process. Window 95 introduced preemptive scheduling and Mac also uses this scheduling process. Bharat Rawal
What is the difference between cooperative multitasking and preemptive multitasking?
Cooperative multitasking is multitasking tohelp someone else, while peemative multitasking is multiaatsking for yourself.
Which funtcion is performing when an operating system receives an interrupt from the printer and pauses the CPU?
In traditional programming parlance, an interrupt is handled by an Interrupt Handler. The CPU is not actually paused, but the current process that was running before the interrupt occurred is paused while the CPU processes the request. Once the Interrupt Handler returns, the application will be returned to its original running state. In modern operating systems with multiple tasks, the original application that was running may stay suspended after the interrupt completes in favor of running another process that has been suspended for some time.
