Answer 1

The fundamental differences between traditional 3-tiers and Single Page Application (SPA) and popular technology stacks used to implement them.

Step-by-step explanation:

The fundamental differences between traditional 3-tiers and Single Page Application (SPA) are as follows:

1. In a traditional 3-tier architecture, each tier (presentation, logic, and data) is separate and distinct, whereas in an SPA, all code executes in the same page and updates are made dynamically without requiring a complete page reload.
2. In a traditional 3-tier architecture, data is sent back and forth between the client and server for every action, whereas in an SPA, data is loaded once and subsequent updates are handled through API calls.
3. Traditional 3-tiers follow a request-response model where the client sends a request to the server and waits for a response, whereas in an SPA, the client can make asynchronous calls to the server and continue working on other tasks.

Three popular technology stacks for traditional 3-tiers are:
1. LAMP (Linux, Apache, MySQL, PHP)
2. MEAN (MongoDB, Express.js, Angular.js, Node.js)
3. WAMP (Windows, Apache, MySQL, PHP)

Three popular technology stacks for SPA are:
1. MERN (MongoDB, Express.js, React.js, Node.js)
2. MEAN (MongoDB, Express.js, Angular.js, Node.js)
3. Vue.js with Node.js and Firebase.
