Description: An interrupt vector is a table that associates interrupt signals with their corresponding interrupt handlers. In the context of operating systems and computer architecture, this table is fundamental for managing communication between hardware and software. When a hardware device requires attention from the processor, it generates an interrupt signal. The interrupt vector allows the operating system to quickly identify which handler should manage that interrupt, thus facilitating an efficient and timely response. This structure is especially relevant in real-time operating systems and general-purpose systems, where latency and response speed are critical. In architectures like ARM and x86, interrupt vectors are essential for managing multiple interrupt sources, allowing the operating system to effectively handle concurrent tasks. Additionally, in microkernels, where the goal is to minimize the amount of code running in kernel mode, interrupt vectors play a crucial role by allowing device drivers to run in user mode, enhancing system stability and security. In summary, interrupt vectors are an integral part of modern operating system architecture, facilitating efficient and organized interaction between hardware and software.
