Roles and permissions control what each user can see and do. An admin might manage everything, a staff member might handle orders, and a customer might only see their own account. Roles group permissions so you can assign a whole set of abilities at once instead of one by one.
This matters for security and clarity. Without it, either everyone can do everything (dangerous) or you manage access person by person (unworkable). Roles keep sensitive actions limited to the right people and keep the interface simple for everyone else.
Well-designed roles map to how your organization actually works. Getting them right early avoids painful rework, because retrofitting proper access control into an app that assumed everyone was equal is difficult and risky.

Authentication is how an app confirms who a user is, usually a login with an email and password, a social login, or a one-time code. It's paired with authorization, which decides what that verified user is allowed to do. Together they protect accounts and control access to data.
An admin dashboard is the private, logged-in part of an app where a business manages everything: customers, orders, content, settings, and reports. Users never see it. It's the control room where your team runs the operation, often the most valuable part of a custom build even though it's invisible to the public.
A website mainly shows information: pages you read, like a brochure, blog, or portfolio. A web app is software you use in the browser: it takes input, does something with it, and saves state, like Gmail, a bank dashboard, or a booking system. The line is interactivity and data, not looks.
SaaS (software as a service) is software you access online and pay for by subscription, instead of buying and installing it. You use it in a browser, the provider runs and updates it, and you pay monthly or yearly. Slack, Shopify, and Notion are SaaS. Most business software now works this way.
An MVP (minimum viable product) is the smallest version of an app that delivers real value and can be put in front of users. You start with one because it gets you to real feedback fastest and cheapest, before you spend heavily building features nobody has confirmed they want.
A progressive web app (PWA) is a website that behaves like an installed app: users can add it to their home screen, it can work offline, and it can send notifications, all without going through an app store. It's built with normal web technology, so one build works across devices.
