A computer sends a byte using odd parity. The data bits are 1010011. What is the correct parity bit to append?

Q: How do I try a free CIE Computer Science question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CIE IGCSE Computer Science bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CIE Computer Science students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Computer Science questions aligned to the CIE IGCSE syllabus?

Every question is written against the published CIE IGCSE Computer Science syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CIE past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A computer sends a byte using odd parity. The data bits are 1010011. What is the correct parity bit to append?

Accepted Answer

0, because the data already contains an odd number of 1s — The data bits 1010011 contain four 1s, which is even. To achieve odd parity, a parity bit of 1 must be added, making five 1s in total — wait, let us recount: 1,0,1,0,0,1,1 = four 1s (even). Adding parity bit 1 gives five 1s (odd). Therefore option A is incorrect as stated; the correct answer is B. Correction: 1010011 has four 1s (even), so parity bit = 1 to make total odd. Option C wrongly counts 1s as odd. Option D confuses odd and even parity goals.

Answer

1, because adding it makes the total number of 1s even

Answer

1, because adding it makes the total number of 1s odd

Answer

0, because the data already contains an even number of 1s

Answer

0, because the data already contains an odd number of 1s
