When someone asks "what is a server?" they’re talking about more than just a computer - it’s a dedicated system built to provide resources to other machines over a network and run 24/7 with high reliability. It’s the backbone of online services, from web hosting to streaming platforms. I found a detailed breakdown of this concept and how server hardware and software work together, plus real-world infrastructure insights at https://www.servers.com/news/blog/what-is-a-server . That kind of clarity, explaining both theory and practical mechanics, is what turns confusing tech into something you can actually apply in projects or business planning.
