defined route are added the the routes table when the progam start?

When a program starts the process of adding defined routes to the routes table typically occurs in the context of networking and routing protocols. In networking a route is a path that data packets take from their source to their destination. The routes table also known as a routing table is a data structure used by routers to decide where to forward packets. In a software application or system adding defined routes to the routes table when the program starts involves specifying how different types of traffic should be directed. This can be done statically by configuring the routes manually or dynamically through routing protocols like OSPF (Open Shortest Path First) or BGP (Border Gateway Protocol). For example in a web application running on a server when the program starts specific routes are defined to handle incoming HTTP requests. These routes determine which functions or resources should handle requests for different URLs. Here's a simple pseudo-code example using a web framework like Express in Node.js: const express = require('express'); const app = express(); // Define routes app.get('/' (req res) => { res.send('Hello World!'); }); app.get('/about' (req res) => { res.send('About Us Page'); }); // Start the server const PORT = 3000; app.listen(PORT () => { console.log(`Server is running on port ${PORT}`); }); In this code snippet routes for the root path ('/') and '/about' path are defined when the Express server starts. When a client makes a request to the server the server matches the request URL to the defined routes in the routes table (handled by Express) to determine how to respond. Overall adding defined routes to the routes table when a program starts is essential for efficient data routing and resource handling in various types of software applications and systems.
