In computing, a bus error is a fault raised by hardware, notifying an operating system (OS) that a process is trying to access memory that the CPU cannot physically address: an invalid address for the address bus, hence the name. In modern use on most architectures, these are much rarer than segmentation faults, which occur primarily due to memory access violations: problems in the logical address or permissions.
