VECTOR INTERRUPT If the interrupt is assigned to any predefined branching address to its ISR it is termed as vector interrupt. NON VECTOR INTERRUPT If the interrupt is not assigned to any predefined branching address to its ISR it is termed as non-vector interrupt. PRIYAKRISH
If the interrupt is not assigned any predefined branching address to its ISR it is termed as non interrupt vector
A trap handler, also called an interrupt handler or interrupt service routine (ISR) is a program that executes when predefined events occur in a computer. There are software and hardware interrupts. An interrupt causes the computer's processor to stop running its current task and immediately run the trap handler to service the interrupt.
In the 8085 microprocessor, a hardware interrupt is a signal from an external device that temporarily halts the CPU's current operations to allow the device to communicate with the processor. A vector interrupt specifically refers to an interrupt that has a predefined memory address (vector) associated with it, which the processor jumps to when servicing the interrupt. For instance, the 8085 has several hardware interrupts, such as INTR, RST 7.5, RST 6.5, and RST 5.5, each with its own unique vector address, allowing for efficient and organized handling of multiple interrupt sources. This mechanism enables real-time processing and responsiveness to external events in embedded systems.
An interrupt circuit is used in computer systems to temporarily pause the main program in order to handle a specific event or request, such as a hardware error or input from a peripheral device. When an interrupt occurs, the processor stops its current operation, saves its state, and jumps to a predefined location in memory to execute the interrupt service routine. This helps ensure timely and efficient handling of important tasks while allowing the processor to resume its previous operation afterward.
A parity error always causes a non-maskable interrupt. It doesn't make sense to mask a parity interrupt because if you get parity errors it's not very smart to ignore it. What the effect is depends on the operating system. Usually the NMI jumps to a predefined mem location in the OS and executes whatever the designers put there. Jan Didden
Interrupt is a verb.
An interrupt vector is the memory address of an interrupt handler, or an index into an array called an interrupt vector table or dispatch table. Interrupt vector tables contain the memory addresses of interrupt handlers. When an interrupt is generated, the processor saves its execution state via a context switch, and begins execution of the interrupt handler at the interrupt vector.

the prefix of interrupt is in
The prefix for interrupt is "inter-".
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.
