    Which is a very simple example of an error detecting code?

    • Interrupt

    • Parity bit

    • Asynchronous

    • Data Integrity

    Correct Answer
    A. Parity bit
    Explanation
    A parity bit is a very simple example of an error detecting code. It is a single bit added to a binary code to detect errors during transmission. The parity bit is set to either 0 or 1, depending on the number of 1s in the code. If the number of 1s is odd, the parity bit is set to 1, making the total number of 1s even. If the number of 1s is already even, the parity bit is set to 0. During transmission, the receiver can check if the number of 1s in the received code matches the parity bit. If they don't match, an error is detected.

    • Interface

    • Interrupt

    Correct Answer
    A. Interrupt
    Explanation
    An interrupt is defined as an asynchronous signal from a computer hardware device indicating the need for attention from a CPU or a synchronous event. When an interrupt occurs, it temporarily suspends the normal execution of the CPU and transfers control to a specific interrupt handler routine. This allows the CPU to handle time-sensitive or critical tasks, such as responding to input/output requests or handling errors, without wasting time continuously checking for events. Interrupts play a crucial role in multitasking and real-time systems, ensuring efficient and timely processing of various events and tasks.
