What is middleware scripting?
Middleware scripting refers to server-side scripts that act as a middle layer between the front-end (the website users see in their browser) and the back-end systems such as databases or applications. It helps different systems communicate with each other. For example, when a user submits a form on a website, middleware processes the request, interacts with the database, and sends the correct response back to the browser. Languages such as PHP, Python, Node.js, and Java are commonly used for middleware scripting.
What is the difference between SSH and FTP and why do we use each?
SSH (Secure Shell) is a secure protocol used to remotely access and control a server through the command line. It allows users to run commands, manage files, and configure the server securely. FTP (File Transfer Protocol) is used to transfer files between a computer and a server. Traditional FTP is not secure, but SFTP works over SSH and encrypts the data. We use SSH when we need to manage or control the server, and we use FTP or SFTP when we need to upload or download website files.
