The term “server” is often used in conjunction with IT, computers, net­works and the rest. But what does it actually mean? And what does it mean when they say “the server is down”? First of all: A server isn’t much more than a particularly power­ful central computer to which many other computers (on a net­work) are connected. As the name suggests, the server literally serves clients, which is what the computers connected to it are called. If a server is down, it also means that the functioning of the computers on the same net­work is partially or fully impaired. This is particularly often the case if the central computer is over­loaded – for instance, if too many users want to access a web­site at the same time.
