1.	How many interrupts are there in micro controller?(a) 3(b) 6(c) 4(d) 5The question was asked in an interview for job.My question comes from Microcontroller (8051) topic in chapter Prototyping Embedded Devices of IOT
Answer» The correct answer is (d) 5 The explanation: An interrupt is an external or internal event that disturbs the microcontroller to inform if that needs its SERVICES. There are 5 INTERRUPTS : TIMER 0 overflow interrupt Timer 1 overflow interrupt External Interrupt 0 External Interrupt 1 Serial port events.
