What is a server?

A computer or system that provides resources or services to other systems.

In plain English

A server is a computer whose job is to answer other computers. Websites, email, databases and applications all run on servers somewhere, usually in a data centre rather than under anyone desk.

For a website, the server holds your files and database and does the work of assembling pages. Its resources, how much processing and memory it has and how many other sites share them, set the limits on your site performance.

What to know

Resources are finite
Processing power, memory and storage are shared. Traffic spikes and heavy plugins consume them, and when they run out, pages slow or fail.
Uptime is never perfect
Servers restart, hosts have incidents. Monitoring tells you before your customers do.
One machine, several roles
Web, database, mail and file services may run on the same server or be split across several. Splitting them removes contention.
Location and specification both count
Distance adds latency, specification sets capacity. A CDN mitigates the first, better hosting the second.

Why it matters

Understanding that a real machine with finite resources sits under your website explains a lot. Why traffic spikes cause outages, why an extra plugin can slow every page, and why cheap hosting behaves badly at exactly the moment a campaign lands.

Common mistakes

×Running a growing site on resources sized for its launch traffic.
×No uptime monitoring, so outages are discovered by customers.
×Assuming a slow site is a code problem when the server is saturated.
×No tested backup, so a server failure becomes a rebuild.

FAQs

What is the difference between a server and hosting?

The server is the machine. Hosting is the service that gives you space on one and looks after it.

How do I know if my server is the problem?

Check time to first byte and server response under load. If response time is high before anything renders, the server is where to look.
