Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

https://smallwhale.org/articles/source-code

1. What is the fundamental nature?
2. What is the evolutionary trajectory?
3. Why do we use high‑level programming languages instead of writing binary numbers?
4. How does a computer understand source code?

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the fundamental nature?Human-readable plain text instructions defining software behavior
2. What is the evolutionary trajectory?Progressed from low-level machine code to abstract, high-level programming languages
3. Why do we use high‑level programming languages instead of writing binary numbers?High‑level languages let programmers write ideas in clear words, making it easier to create complex programs. They hide the messy binary details so we can focus on solving problems.
4. How does a computer understand source code?A compiler or interpreter turns the source code into machine code that the processor can run. Compilers translate the whole file at once, while interpreters read it line by line.

High-Level Programming Language: A programming language with strong programming features and easy readability, abstracting away hardware details.
Compiler: A program that translates source code written in a high-level language into machine code or an intermediate representation.
Interpreter: A program that directly executes instructions written in a programming language without previously compiling them into machine code.
Just-In-Time (JIT) Compilation: A method of executing code that involves compiling parts of the code at runtime to improve performance.
