A server, PC or laptop actually converts almost all the electrical power consumed into heat - right? A server without moni and speakers actually only generates heat, so how should one evaluate his actual "work", ie information processing in such a way physically?
Each lamp can be more…
How is "work" defined in physics?
You have quite a PC generated to 70% heat and the remaining 30% work in progress.
A lamp can only be on / off and generates 100% heat.
A computer is a masterpiece of technology, alone historical, but the components that need to be processed, "multitasting" the PC can do 100 things "at the same time" how many do you create?
100% heat is not right. Light is still there.
Basically yes. Although the information content on your hard disk can be assigned a certain entropy, which hopefully increases as a result of your work on the PC. But you can safely neglect that.
What a pc really does for you, save for life's sake: It simplifies your thinking and that's a lot of energy in the form of gurneys and lard you save on food.
Sorry 90% heat 10% light
Well, what kind of work? An electric motor generates not only heat torque, power, movement. A server - does not look like that, right? Take, process and give data and music streams are physically not work, right?
From this point of view, IT is ecologically the most absurd, egoistic thing that man invented…)

So nothing a server can do.
Exactly. He does work in the human sense.
That's true, of course, but it's an indirect work, so to speak. Did not ask the question either, because I'm an IT hater or something, on the contrary. But thinking must be allowed…
"100% heat is not right, light is still there" That's often true, but not with servers.
You have to consider the whole thing thermodynamically Grand Canyon. At a certain scale, it becomes clear that in addition to the thermal energy, the PC primarily provides chemical energy - in the form of the calories saved, and these correspond exactly to the mechanical friction work.
