What is the performance advantage in having device drivers and devices synchronize by means of device interrupts?
Using device interrupts for synchronization between device drivers and devices enhances performance by allowing the CPU to execute other tasks instead of polling for device readiness. This event-driven approach reduces CPU usage and latency, as the CPU can respond instantly when an interrupt signals that the device requires attention. Consequently, it improves overall system efficiency, enabling better multitasking and responsiveness in applications.

How interrupts increase the performance of the CPU?
Without interrupts the software must be continuously polling all of the hardware I/O devices to determine their status. Interrupts allow the hardware I/O devices to inform the software when their status has actually changed, thus the software can briefly suspend what it was doing to check the status of the one specific hardware I/O device that sent the interrupt and take care of it then resume what it was doing. Without having to spend all that time polling devices whose status has not changed much less processor time is wasted, thus increasing average performance. Being able to begin handling the device as soon as its status changes instead of having to wait for the next time it is polled, increases realtime performance.
What is the command used to check IRQ?
To check IRQ (Interrupt Request) settings in a Linux system, you can use the command cat /proc/interrupts. This command displays a list of all interrupts, their corresponding IRQ numbers, and the associated devices using those interrupts. For a more detailed view, you can also use lspci -vv to see which devices are assigned specific IRQs.
Interrupts originate with what?
Interrupts originate from hardware or software events that require immediate attention from the CPU. Hardware interrupts are generated by devices such as keyboards, mice, or network cards to signal that they need processing, while software interrupts can be triggered by system calls or exceptions in programs. These interrupts allow the CPU to respond quickly to changing conditions or requests, ensuring efficient multitasking and system responsiveness.
Different between maskable and non-maskable interrupt?
Maskable interrupts trigger events are not always important and so the programmer can decide that the event should not cause a program to jump. Nonmaskable interrupts can not be ignored by the programmer and therefore they have absolute priority.
What are the advantages of using hardware interrupts?
Hardware interrupts provide several advantages, including improved efficiency and responsiveness in processing tasks. They allow the CPU to handle asynchronous events without constantly polling devices, freeing up processing time for other tasks. Additionally, hardware interrupts enable real-time processing, as the CPU can immediately respond to high-priority events, ensuring timely execution of critical operations. This leads to better resource utilization and enhanced overall system performance.
Does FitBit app need to use bluetooth to sync to your phone?
FitBit app need to use Bluetooth to synchronize your phone with other devices.
How do you synchronize sony lcd tv remote and videocon dth remote?
When trying to sync your Sony television with your Videocon rote, refer to the owner's manual for both devices. If the devices are not compatible, you will not be able to sync them.
What is a single charge to clock wire is called?
A single charge to clock wire is called a "pulse." This pulse is used to synchronize electronic devices and systems.

What is handshake signal in microprocessor 8086?
I/O devices accept or release information at much slower rate than the microprocesor. Handshaking is the method that synchronize the I/O device with microprocessor.
Non vectored interrupt?
Stopping program flow to execute a special piece of code that handles a event.Non vectored interrupts are generally raised by input/output or slow devices.
