timer interrupt

[ˈtaɪmər ˈɪntərʌpt]
nounpl: timer interrupts
interrupção de temporizador
1. A hardware or software signal that interrupts the normal execution of a processor at regular intervals, typically used for scheduling tasks, context switching, or time-based event handling in operating systems
The operating system uses a timer interrupt every 10 milliseconds to switch between running processes.
O sistema operacional usa uma interrupção de temporizador a cada 10 milissegundos para alternar entre processos em execução.
2. A mechanism that triggers an interrupt request (IRQ) when a preset time interval expires, allowing the CPU to handle time-dependent operations
Without a timer interrupt, the scheduler cannot fairly allocate CPU time among multiple threads.
Sem uma interrupção de temporizador, o agendador não pode alocar equitativamente o tempo de CPU entre vários threads.
This is a specialized term used primarily in computer science and systems programming communities. In both Brazil and Portugal, technical professionals often use the English term 'timer interrupt' in professional contexts, though 'interrupção de temporizador' is the formal Portuguese equivalent. The term is essential for understanding operating system concepts and is consistently taught in university computer science programs across Portuguese-speaking countries.
