Short answer
Web hosting is storage and a runtime environment on an internet-connected server. It keeps a website’s files, databases and, depending on the plan, email available so visitors can reach the site through its domain name.
Web hosting in short
A website does not live inside its domain name. The domain is its memorable address; web hosting is the infrastructure that stores and serves the content behind that address.
When someone opens a web address, DNS points the browser to the correct server. The hosting server then returns static files or generates the requested page with an application and database.
Good to know: Domain, hosting and SSL are separate services, but they work closely together to make a website available securely.
What happens when a visitor opens a website?
1. The browser looks up the domain
DNS identifies which hosting server is responsible for the address.
2. A secure connection is established
With HTTPS, the SSL certificate helps encrypt traffic between the browser and server.
3. The server handles the request
It returns a static file or builds a page with the website application and its database.
4. The page is rendered
The browser loads the HTML, CSS, JavaScript and media needed to display the website.
What can web hosting store?
Uploaded images are not the only items that use storage. Databases, email, logs, caches and application updates can all increase usage over time.
- HTML, CSS and JavaScript files;
- images, documents and downloads;
- content management systems such as WordPress;
- MySQL or other supported databases;
- email accounts and messages;
- logs, caches and temporary files.
Storage and data transfer are different resources
Storage
The amount of data that can be kept on the server, including site files, databases and potentially email.
Data transfer
The data sent between the server and visitors. More visitors and larger files generally use more transfer.
Processing resources
CPU and memory used by the application. A busy or complex website may need more of both.
Good to know: A plan with more storage does not automatically include unlimited processing power. Compare all relevant limits together.
What do PHP, databases and the control panel do?
PHP is a common server-side programming language. Many content management systems and web applications, including WordPress, use it to generate pages.
A database stores structured information such as posts, products, settings or user records. The application retrieves that information and presents it in the required format.
A hosting control panel provides tools for managing domains, email accounts, databases, files and security settings. DES Hosting plans use InterWorx.
What makes hosting safer and more reliable?
Provider backups are an important layer of protection, but critical websites should also keep an independent copy outside the hosting account.
- a valid SSL certificate for HTTPS;
- regular backups and a clear restoration process;
- up-to-date applications, plugins and credentials;
- separate user access with appropriate permissions;
- a monitored server environment and reachable support.
What kind of hosting do you need?
The right choice is not simply the plan with the most gigabytes. Website type, expected traffic, email use, databases, backups and support requirements all matter.
If you do not yet know how much storage you need, estimate current site and email usage first, then leave room for growth.
Frequently asked questions
Short answers about this topic
Are a domain and web hosting the same thing?
No. A domain is the website’s address, while hosting is the server environment where its files and data are kept.
Can a website work without hosting?
A public website must be served by an internet-connected system. That can be shared web hosting, a private server or another cloud environment.
Does web hosting include email?
Many plans include email, but account counts, storage and other limits vary and should be checked in the plan details.
Is a larger hosting plan always faster?
Not necessarily. Server performance, website code, caching, network conditions and resource limits also affect speed.
