Hosting Terms
What is MySQL?
MySQL in plain English — the meaning, the comparison, and why it matters to anybody running a website.
Straight answer first
MySQL is the relational database behind most hosted applications — the structured store where WordPress keeps every post, every user and every setting.
Below: the fuller explanation, a picture that makes it stick, why it matters in practice, and where you will actually run into it.

To read, naturally
Applications talk to it in SQL. Hosting panels create the databases and their users, phpMyAdmin gives you a window into the contents, and MariaDB serves as the drop-in open-source twin used across much of the trade.
Its speed shows up everywhere caching does not reach: admin screens, site search, checkout. That is why putting databases on NVMe storage changes how a dynamic site feels to use.
The picture that makes MySQL stick
The stock ledger kept behind the counter. Every record can be found on request, and how quickly that ledger can be read sets the pace for everyone waiting on the other side of it.
Comparisons simplify, naturally — but this one holds together well enough to reason with, and reasoning is the whole point of a glossary.
Why this one is worth knowing
Your content lives in there. A site backup without the database is decoration, database bloat is the classic reason a site slows down, and one exported .sql file holds the whole of your site's memory in portable form.
You do not need to work at this layer every day. You need to recognise it when it explains something, which is exactly the moment this page earns its keep.
MySQL out in the open
A WooCommerce order drops into MySQL tables the instant checkout completes — the same tables the dashboard reads back, the reports add up, and the nightly backup carries away.
Perfectly ordinary once you have seen it, which is rather the point: most hosting concepts are simple machinery wearing an intimidating name.
The Hosting Seller angle
On our hosting this largely looks after itself — the platform applies sensible defaults, and the panel hands you the controls when you want them. The concepts worth reading next: Database, PHP, NVMe and Backup.
Mailboxes on your own domain are part of the plan, never an add-on sold back to you at checkout.
A glossary written by the people on the counter
Every confusing term in hosting turns into a support ticket sooner or later, so we defined the hundred most common ones properly, once, in the plain English we would use across the counter.
Order an annual plan and the first year of your domain registration is on the house.

Why Hosting Seller
On every plan, as standard
The stakes spelled out
Not only what it is, but when it turns out to be the answer to a problem you are having.
Plain English first
Every term defined for people who run sites, not for other sysadmins — jargon translated rather than restated.
Grounded in real kit
Examples point at hosting you would actually use, not at an abstract diagram.
The next reads, mapped
Read on into Database and PHP — terms rarely stand alone, so the neighbours are linked.
Pictures that stick
Each concept gets a comparison you will still remember at the moment you actually need it.
Linked, never siloed
Related terms cross-reference each other, so one lookup grows into a working understanding.
First Steps
From choosing to live
- 1
Find it in your own account
Open the control panel and find where this concept lives — seeing it attached to your own site is what turns a definition into understanding.
- 2
Check what the defaults are
Our platform ships sensible defaults for this — check rather than assume, and you will know your setup instead of hoping about it.

Follow the terms next door

Across the Counter
The questions we get asked most
MySQL or MariaDB — does the difference ever reach me?
For hosted applications, almost never. MariaDB is a compatible fork and applications speak to either without noticing. The name on the label matters far less than the disk it sits on and the indexes inside it.
How do I take a backup of a MySQL database?
Panel backups include databases, a phpMyAdmin export gives you a portable .sql file, and WP-CLI with cron can automate dumps on a schedule. Any of the three will do. The only real mistake is having none, or never testing that the one you have restores.
What does round-the-clock support actually stretch to?
People at the counter at every hour, and a scope that takes in the practical work: mailbox setup, DNS records, WordPress trouble, restores. Not 'the server responds, ticket closed'. Ask us something hard before you order — the reply is a fair sample of what you would get afterwards.
How do I read the mail when I am away from the desk?
Webmail opens in any browser, and every mailbox also speaks IMAP, POP and SMTP — so the mail app on your phone, the client on your desktop and webmail all show the same messages in the same order.
Can one plan hold more than a single website?
From the Pro tier upward, yes — several sites, each with its own domain, mailboxes and certificate, all under one account. If those extra sites belong to clients rather than to you, reseller hosting is the better fit: it gives each one proper separation.
Can I bring a domain I already own?
Yes, and transfers in are routine. Unlock the name at your present registrar, collect the auth code, then start the transfer from your client area. Whatever registration time is left comes across with it, and DNS keeps answering the whole way through.
Which control panel comes with the account?
cPanel, which the whole trade already knows. That means every tutorial online matches what you see, your backups restore onto any cPanel host anywhere, and what you learn here stays useful for life. Plesk and DirectAdmin are stocked on specific plans for anyone who prefers them.
