Question

what is the most common knowledge computer programmers need in order to write programs?
a. how to build computers from basic components
b. a high - level programming language, such as swift or javascript
c. the full history of the computer and its development
d. how a computer converts binary code into a programming language

Explanation:

Computer programmers need to know a high - level programming language (such as Swift or JavaScript) to write programs. Building computers from basic components (A) is hardware - related, not programming. The full history of the computer and its development (C) is more of a historical or general knowledge topic rather than a direct need for writing programs. How a computer converts binary code into a programming language (D) is about the computer's internal operation at a lower level, not what a programmer directly needs to write code.

Answer:

B. A high - level programming language, such as Swift or JavaScript
