Trap vs. Interrupt: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on November 30, 2023
A trap is a software-generated interrupt triggered by an error or specific condition in a program, while an interrupt is a hardware or software signal that pauses CPU operations to handle an event.

Key Differences

A trap, in computer terms, is a type of interrupt specifically initiated by software, typically to signal an error or request a service from the operating system. An interrupt, however, can be either hardware or software-based, serving as a signal that temporarily halts CPU operations to address an event or execute a higher-priority task.

Traps are often used to handle exceptions in software, such as illegal operations or division by zero. Interrupts, on the other hand, can be triggered by external devices (like a mouse click) or internal conditions (like a timer expiring), indicating a need for immediate attention by the CPU.

A trap is a mechanism for the operating system to take control and perform specific operations, like managing a system call from a program. Interrupts serve a broader purpose, managing the interactions between the CPU and external or internal events, ensuring efficient processing and response.

Traps are crucial in debugging, as they can signal problems within a program's operation, allowing for corrective measures. Interrupts, conversely, are essential for multitasking and real-time processing, allowing the CPU to respond quickly to various events without continuous polling.

The handling of a trap usually involves executing a predefined routine to manage the specific issue or request. Interrupt handling involves the CPU pausing its current task, saving its state, processing the interrupt, and then resuming the original task.
