Can someone clearly explain terminals, shells, editors, and development environments?

I'm a beginner trying to understand common programming terms such as terminal, shell, editor, and environment. Online explanations often seem confusing or assume background knowledge. Could someone explain the differences in simple language and suggest a clear learning path or reliable resources?
Answers
When asking about a term, explain what you currently think it means and where you encountered it. That gives people enough context to correct misunderstandings and avoid giving an explanation that is too advanced or too broad. A structured beginner course or book is usually clearer than jumping between unrelated search results.

A terminal is the application window where you enter text commands. The shell is the program running inside that window that interprets those commands and executes programs. Bash is common on Linux and macOS, while PowerShell and Command Prompt are common on Windows, although several shells and terminals can be used on each operating system. For example, listing files is usually done with `ls` in Bash and `dir` in Command Prompt.

The phrase development environment usually means the collection of tools and settings you use to build software: your operating system, editor or IDE, programming languages, libraries, packages, compilers, and command-line tools. It can also refer to a particular setup for a project, such as a Python version and its installed packages. The exact meaning depends on the context, so it is reasonable to ask which kind of environment someone means.

An editor is a program for writing and changing code files. Examples include VS Code, Sublime Text, Vim, Emacs, and Nano. An integrated development environment, or IDE, includes an editor plus additional tools such as a debugger, compiler or build support, code completion, testing tools, and project management. Visual Studio and PyCharm are examples. VS Code sits somewhere in between a basic editor and a full IDE because extensions can add many of those features.

You do not need to understand every tool before starting. Pick one beginner-friendly language and work through small exercises while learning basic commands such as `cd`, `ls`, `mkdir`, `cp`, `rm`, `grep`, and `find`. As you use them, the terminology will become easier to connect. It is also useful to learn how to search for a specific error or command instead of trying to memorize everything at once.

MellowPine47: That distinction helps a lot—I was treating the terminal and shell as the same thing.
