Servers are the backbone of the internet. They deliver websites, applications, media, email, cloud services, and countless other resources people rely on every day. Without servers and the networks that connect them, the internet as we know it would not exist.

The subject of servers and networking is nearly endless, ranging from small home labs and business networks to data centers that support major websites and large-scale online services.

As companies replace older equipment with faster and more energy-efficient systems, powerful enterprise hardware has become far more affordable. Giving individuals, hobbyists, and small businesses the opportunity to build, learn from, and operate systems that were once available only to large organizations.
