Not really the way it used to be. There are still "huge" mainframe-type supercomputersaround for doing really complex scientific stuff, but the traditional datacenter is now packed with row upon row of blades....a blades is basically a card with many cores and memory on-board and a box that may contain many of these blades. The operating system would be a virtual OS hosting many 1000s of instances of windows or lInux. Each instance might be a application, a part of an application, a database server, etc. The rest of the datacenter is filled with UPS units (Uninterrupted Power Supply) and disk farms.
And of course, every office area has at least one printer
