MCQ (Single Correct Answer)

-0.3

Which one of the following is true for a $$CPU$$ having a single interrupt request line and single interrupt grant line?

Neither vectored interrupt nor multiple interrupting devices are possible

Vectored interrupts are not possible but multiple interrupting devices are possible

Vectored interrupts and multiple interrupting devices are both possible

GATE CSE 2002

MCQ (Single Correct Answer)

-0.3

In serial data transmission, every byte of data is padded with a $$‘0’$$ in the beginning and one or two $$‘1’s$$ at the end of byte because

Receiver is to be synchronized for byte reception

Receiver recovers lost $$‘0’s$$ and $$‘1’s$$ from these padded bits

Padded bits are useful in purity computation

None of the above
