What is the advantage of using interrupt initiated data transfer?

It does not require the continuous checking of I/O port by the computer . The computer checks the port only when an I/O interrupt is encountered . It saves processing time.

Difference between programmed IO and interrupt IO?
1.Programmed IO is the process of IO instruction written in computer program , where Interrupt Initiated IO is done by using interrupt and some special command. 2.The advantage of Interrupt Initiated IO is ,it is a time consuming process than Programmed IO. 3.In Programmed IO technique to transfer data,required constant motoring on peripheral by CPU,once data transfer is initiated, CPU have to wait for next transfer. In Interrupt Initiated IO once data transfer initiated ,CPU execute next program without wasting time and the interface keep monitoring the device. When the interface determines that the device is ready to transfer data, it generate an interrupt request,CPU stop the current task,execute the transferring process,and then return to the previous on-processing task.
What type of data transfer is carried out using a USB port?
The type of data transfer that is carried out using a USB port are varied. Some of the types of data transfer include bulk data transfer, isochronous data transfer and interrupt data transfer among others.
How interrupt is performed using 8259-?
The interrupt process is simple. The 8259 is combined with many interrupts inputs.
Interrupt in a sentence?
Here is an example sentence using the word interrupt. Bill will always interrupt Sally when she is telling a story about him.
Why does DMA interrupt the CPU when ready to transfer?
DMA (Direct Memory Access) does not actually interrupt the CPU - it requests control of the bus, so that it can perform the transfer itself. It becomes a bus-master. This is done using the HOLD and HLDA (Hold Acknowledge) control pins. This is not the same thing as an interrupt, which is where an external device requests the CPU's attention, and the CPU goes off and performs some code to service that request. In the case of DMA, the CPU actually freezes for the few cycles that the DMA controller requires, which is much, much more efficient than using an interrupt service routine.
How do you disable Interrupt request lines?
The interrupt request lines on the 8085 (INTR, RST7.5, RST6.5, and RST5.5) can be disabled using the DI (Disable Interrupt) instruction. You re-enable with the EI instruction. Also, RST7.5, RST6.5, and RST5.5 can be individually enabled and disabled using the SIM (Set Interrupt Mask) and RIM (Read Interrupt Mask) instructions. The TRAP interrupt request line cannot be disabled.
Where is interrupt handler and interrupt vector?
In the 8086/8088, the interrupt vector table is the first 1024 bytes of memory. In the 8085, the interrupt vector table is the first 64 bytes of memory if using the RST form of interrupt, otherwise the interrupt vector is provided by the interrupting device, usually in the form of a CALL instruction. The interrupt handler is wherever the interrupt vector points to.
What is a sentence using the word interrupt?
