A student is comparing a compiler and an interpreter. She notes that when using a compiler, the program runs more slowly than when using an interpreter because the compiler checks the entire code first. Which of the following correctly evaluates her statement?

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 student is comparing a compiler and an interpreter. She notes that when using a compiler, the program runs more slowly than when using an interpreter because the compiler checks the entire code first. Which of the following correctly evaluates her statement?

Accepted Answer

The statement is incorrect — compiled programs generally run faster because the translation is done before execution — Award 1 mark for identifying that compiled programs run faster than interpreted programs. Because a compiler translates the entire source code into machine code before execution, the resulting object code can be executed directly by the processor without any translation overhead at runtime. Interpreted programs require translation at runtime for each line, which introduces execution delay. A is incorrect — this is the opposite of the accepted understanding; compiled code runs faster. C is incorrect — there is a measurable and well-documented speed difference between compiled and interpreted execution. D is incorrect — file size is not the reason for any speed difference; the translation overhead during execution is the key factor.

Answer

The statement is incorrect — compiled programs generally run faster because the translation is done before execution

Answer

The statement is correct — compiled programs always run more slowly than interpreted programs

Answer

The statement is correct — compilers produce larger files which take more time to execute

Answer

The statement is incorrect — both compilers and interpreters produce programs that run at the same speed
