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.
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.
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 the advantage of usb connector?
add devices without restarting
What is a program that assesses and reports information about various computer resources and devices?
performance monitors
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.
Modern measuring devices take advantage of new technologies to perform more accurate measurements than older devices?
yes
What is the purpose of a 15 sync terminal adapter and how does it function in electronic devices?
A 15 sync terminal adapter is used to synchronize electronic devices by providing a common connection point for data transfer. It functions by allowing devices to communicate and share information through a standardized interface, ensuring accurate timing and coordination between them.
What does dark noise do and how does it affect the performance of electronic devices?
Dark noise is random electrical fluctuations that occur in electronic devices even when they are not in use. This noise can interfere with the signals being processed by the device, leading to errors in performance and reduced accuracy. In essence, dark noise can degrade the overall performance of electronic devices by introducing unwanted disturbances in their operation.
