Key Concepts & Vocabulary
TermDefinitionExample
DeploymentThe process of making software (like a website or app) available for users to access and use.When you finish coding your website and upload it to a server so others can visit it, you are deploying it.
ServerA powerful computer that stores and delivers websites, apps, and data to other computers (clients) over a network, like the internet.When you type 'google.com' into your browser, a Google server sends the webpage files to your computer.
ClientThe computer or device (like your phone, laptop, or tablet) that requests and receives information from a server.Your web browser (e.g., Chrome, Safari) acts as a client when it asks a server for a webpage.
HostingThe service of storing a website or application's files on a server and making them acce...

Core Syntax & Patterns
The Client-Server Communication Rule
Client -> Request -> Server -> Response -> Client
This fundamental rule explains how web applications communicate. Your browser (client) sends a request for a webpage to a server, and the server sends the necessary files (HTML, CSS, images) back to your browser (client) to display.
The 'Test Before You Deploy' Rule
Develop -> Test Locally -> Fix Bugs -> Test Locally Again -> Deploy
Always test your code thoroughly on your own computer (locally) before making it available to the public. This helps catch errors and ensures your application works as expected before anyone else sees it.
The 'Keep It Updated' Rule
Deploy -> Monitor -> Update -> Redeploy
Software is rarely 'set i...

Challenging
A developer's code for an image is `<img src="/app/images/logo.png">`. This works on their hosting platform but is broken on their local machine. What does this suggest about the file path?
A.It is a relative path that works only on the server's specific file structure.
B.It is an absolute path on the server, which is different from the local machine's path.
C.The image file was not saved correctly before being uploaded.
D.The local machine does not have a web browser installed.
Challenging
Which of the following represents the most complete and correct workflow for creating and launching a simple static website, according to all the tutorial's concepts and pitfalls?
A.Get hosting -> Write code -> Deploy -> Get domain name -> Test live.
B.Write code locally -> Save files -> Test locally -> Get hosting/domain -> Deploy files -> Test live site.
C.Write code -> Deploy -> See errors on live site -> Fix errors on live site -> Save.
D.Get domain name -> Point it to your local computer -> Write code -> Ask friends to connect to your computer.
Challenging
A student deploys their website and never touches it again. Why might this become a problem, even for a simple static site, based on the principle of 'updates and maintenance'?
A.The HTML and CSS code will 'expire' after one year and stop working.
B.The domain name will automatically be given to someone else.
C.The hosting platform or browser technologies might change, causing parts of the site to break or become insecure over time.
D.Static sites automatically delete themselves if not updated.
