Console App: This refers to any application that runs in a command-line interface (CLI) environment. Examples include Command Prompt (CMD), PowerShell, or other terminal-based tools. It is a general term for programs that interact with users via text input and output.

PowerShell: This is a specific command-line shell and scripting language developed by Microsoft. It is used for task automation and configuration management, offering advanced features like object-based pipelines and integration with Microsoft services.

Windows Terminal: This is a modern terminal application introduced in Windows 11. It acts as a host for multiple shells, including PowerShell, Command Prompt, and others. It provides features like tabs, customizable profiles, and enhanced text rendering.

Key Difference: A console app is a broad category, while PowerShell is a specific tool within that category. PowerShell can run inside a console app like Windows Terminal or the older Console Host.

Windows Terminal vs. PowerShell: Windows Terminal is not a replacement for PowerShell. Instead, it is a platform where PowerShell and other shells can run. You can switch between shells (e.g., PowerShell, CMD) within Windows Terminal.
