How does source code differ from machine code?

Source code is only used for documentation, while machine code is the actual program

Source code is written in binary, while machine code is written in a high-level language

Source code is executed directly by the CPU, while machine code requires translation

Source code is human-readable, while machine code is binary and directly executable by the CPU

A developer is building a website where users submit forms and the server must process the data, interact with a MySQL database, and generate dynamic HTML pages. The processing must happen on the web server, not in the browser. Which language is specifically designed for this server-side role?

JavaScript — a client-side scripting language

PHP — a server-side scripting language used for web development

Assembly — a low-level machine language

C — a low-level compiled language

A company is developing a high-frequency trading system where execution speed is critical. They are choosing between a compiled language (C++) and an interpreted language (Python). The team values rapid prototyping but the final system must have minimal runtime overhead. Which approach best balances these competing needs?

Prototype in Python for speed of development, then rewrite the performance-critical components in C++

Use an interpreter for C++ to get both speed and rapid iteration

Use Python exclusively because it is easier to write and maintain

Use C++ exclusively because it is faster, ignoring the prototyping benefit

What is a 'commit' in version control?

A separate copy of the codebase for experimental work

A snapshot of changes made to the code at a specific point in time

The process of combining two branches into one

A file that contains the entire history of the project

Why is Python often described as 'readable'?

It uses curly braces to define code blocks

Its syntax uses indentation and clear, English-like keywords

It is compiled into a human-readable bytecode

It requires explicit type declarations for all variables
