Lesson 11.2 – What is Web Hosting?

Introduction

In the previous lesson, we learned that a domain name is the address of a website. However, having a domain name alone is not enough. A website also needs a place where all its files, images, videos, databases, and code can be stored.

This storage space is called Web Hosting.

Whenever someone visits a website, the browser requests files from a hosting server. The server sends the required files back to the browser, allowing the website to appear on the screen.

In this lesson, we will learn what web hosting is, how it works, different types of hosting, and how hosting and domain names work together.

What is Web Hosting?

Web hosting is a service that stores website files on a server and makes them accessible on the internet.

Definition

Web hosting is the process of storing website data on a server that is connected to the internet 24/7.

Without hosting:

Website files cannot be accessed online.
Visitors cannot open the website.
The domain name has nowhere to point.

Understanding Web Hosting with a Real-Life Example

Think of a website as a house.

Website Component	Real-Life Example
Domain Name	House Address
Hosting Server	House Building
Website Files	Furniture and Items Inside House

Example:

Address = www.mywebsite.com
Building = Hosting Server
Files = HTML, CSS, Images, Videos

Just as people need an address to find a house, users need a domain name to find a website.

How Web Hosting Works

When a website is uploaded to a hosting server, the server stores all website files.

Process

Step 1

Website files are uploaded to a hosting server.

index.html
style.css
images/
videos/

Step 2

A domain name is connected to the hosting server.

Example:

www.mywebsite.com

Step 3

User enters the domain name in a browser.

Step 4

DNS finds the server’s IP address.

Step 5

The browser requests website files.

Step 6

The server sends files to the browser.

Step 7

The website appears on the user’s screen.

What is a Web Server?

A web server is a powerful computer that stores website files and delivers them to visitors over the internet.

Popular web servers include:

Apache
Nginx
LiteSpeed
Microsoft IIS

The server remains online all day and night so visitors can access websites anytime.

Hosting stores these files.

Domain:

www.johnportfolio.com

When visitors enter the domain name, the hosting server delivers these files and displays the website.
