Unit 5 · System Software and Operating System Paper 2 CS · September 2022

Given below are two statements: Assertion (A) and Reason (R).
Assertion (A): A load-and-go assembler avoids the overhead of writing the object program out and reading it back in.
Reason (R): This can be done with either a one-pass or a two-pass assembler.
Choose the correct answer.

Pick an option to check yourself, or open the answer below.

Show answer & explanation

Correct answer: A. Both (A) and (R) are true and (R) is the correct explanation of (A)

Explanation

A load-and-go assembler places the object code directly in memory and runs it, saving the write-out/read-back. Beck notes this can be done with a one- or two-pass assembler. Both statements come from the same description.
