How does a website work?

When we open a website, several processes undergo in the background.

At a basic level, accessing a website involves communication between the device, a web browser, and systems that provide the website's content.

The basic flow: User -> Web Browser -> Internet -> Websites System's -> Response -> Browser

• Enter a website address into the browser.
• The browser sends a request over the internet.
• The request reaches the server where the website is hosted.
• The server processes the request and retrieves the required resources or data.
• The server sends a response back.
• Browser displays the website.

This entire process usually happens very quickly, which is why a website can appear almost instantly after we just select it.

For a simple website, the response might mainly contain files such as HTML, CSS, and JavaScript. But, for a more interactive website, the server may also communicate with databases, APIs, or other services before returning the required information.

The technical details behind this process --- including domains, DNS, servers, URLs, HTTP, and browsers will be explored individually throughout this series.

Constituents of a Website

Although websites can in appearance, functionality, Most modern websites involves several fundamental concepts and components but the basic ones are:

Front-end

Front-end is the user-facing part of the website or application that people see and interact with directly in their web browsers.

It includes some of the elements such as:

• Text
• Images
• Buttons
• Menus
• Forms
• Layout
• Interactive elements

The front-end is mainly responsible for presenting the websites interface to the users.

Back-end

Back end is the server-side, Invisible layer of website or application that handles data processing, Business logic and database management.

It is responsible for tasks such as:

• Processing requests

Database

A database is an organized collection of digital data or information stored electronically in a computer system so it can be easily accessed, managed, and updated.

A database can store things such as:

Therefore, databases are important for websites and web applications for the need to manage changing information.

Types of websites

Websites can be categorized for different purposes and needs. Some are created for providing information, while others support transactions, communications, learning, or for online services.

While websites vary by purpose, They all fall into one of two technical categories based on how they store and display content: Static or Dynamic.

Static Website

A static website is a web page made up of fixed HTML files that are delivered directly to a user's browser without any back-end database or server-side processing

They are useful when the content does not need frequent user-specific changes or complex server-side processing.

Dynamic Website

A dynamic website is a site that changes its content, layout, or user experience in real-time based on user actions, preferences, or data from a database.

These kinds of websites usually require more back-end processing and often work with databases.

Business websites

A business website represents a company or organization online. It serves as a company's official digital profile, designed to share information about services and products, build trust with customers, and generate leads.

E-Commerce website

An e-commerce website is an online store that allows businesses to display products, accept secure payments, and sell directly to customers over the internet.

Social networking websites

Website and Web Application: Difference

The terms Website and Web Application are sometimes used interchangeably, but can describe different online experience.

A website can primarily become informative and designed for users to read and view content. Whereas, a web application generally provides interactive functionality which allows the users to perform several tasks or manipulate data.

This distinction may not always be true. Some modern websites can include highly interactive features/functionalities, while web applications can also contain informational content.
