What is a server on the web? Definition of a Web Server
A web server is a computer system or program that keeps website files and sends them to users when they ask for a webpage through a browser.
A web server is what makes webpages show up on the internet.
What is a Web Server?
A web server is a computer that gets requests from web browsers and sends back web pages, pictures, videos, and other content from the website.
The web server handles the request and provides the files needed for the browser to see the page every time someone visits a website.
What is a Web Hosting Server?
The definition of a web hosting server is the real or virtual server where a website’s files are kept so that they may be viewed online.
When a website owner buys hosting, their website’s data is stored on a server that is connected to the internet. This lets people from all over the world get to the site.
For instance:
- A person who owns a website uploads files to a server that hosts them.
- A person types the URL of the website into a browser.
- The server sends the page to the browser.
- The server sends the page to the person who is visiting.
This whole thing only takes a few seconds.
Important Jobs of a Web Server
Web servers do a lot of crucial things that keep websites running smoothly.
1. Keeping website data safe
A web server stores all the files that make up a website, like
- Documents in HTML
- CSS style sheets
- Scripts written in JavaScript
- Pictures and videos
- Database
These files are kept so they can be sent to users when they need them.
2. Answering Requests from Browsers
The browser sends a request to the web server every time someone views a webpage.
The server then:
- Gets the request
- Finds the resource that was asked for
- Returns the file to the browser
After that, the browser shows the user the webpage.
3. Keeping track of web traffic
Web servers are built to handle a lot of requests at once. A server makes sure that every user gets the page they asked for, even when a lot of people are on the site at the same time.
4. Helping to Keep Connections Safe
HTTPS is used by most modern websites to encrypt the connection between the user and the server. This keeps private information like passwords, payment information, and personal information safe.
How Web Servers Work in Real Life (Step by Step)
When we look at how the process works in real life, it becomes much easier to understand what a web server is.
Let’s make things easier by breaking it down.
Step 1: The User Types in a Web Address
When someone types a website URL into a browser, the procedure starts.
For example:
www.example.com
Now the browser needs to find the server that has this website on it.
Step 2: DNS translates the domain name
The browser gets in touch with a DNS (Domain Name System) server. DNS turns the domain name into an IP address, which tells you where the web server is.
For example:
example.com to 192.168.0.1
The browser now knows where to send the request.
Step 3: The browser asks the web server for something.
After the IP address is found, the browser sends an HTTP request to the web server to get the page.
The request could, for example, ask for the file for the homepage.
Step 4: The Server Handles the Request
After getting the request, the server does a number of things:
- Checks to see if the file you asked for exists
- If necessary, it runs scripts like PHP or Python.
- If the page is dynamic, it gets data from databases.
Step 5: The server sends back the answer.
The server sends the webpage files back to the user’s browser after everything has been processed.
The answer can include:
- How to structure an HTML page
- CSS design parts
- Pictures and files for media
- Code in JavaScript
Step 6: The page shows up in the browser.
The browser puts all the files together and shows the webpage on the user’s screen.
Most of the time, the whole thing barely takes a few seconds or even milliseconds.
A Web Server in Real Life
Let’s look at a basic example from real life.
For example, reading a blog online
Think about how you would like to read a blog post.
This is what goes on behind the scenes:
- You enter the address of the website in your browser.
- The DNS server gets in touch with the browser.
- The server’s IP address comes from DNS.
- The web server gets a request from the browser.
- The server gets the files for the blog page.
- The server transmits the files back to your web browser.
- The article shows up on your screen in the browser.
This everything happens in a flash.
