Enigma was way before computers, it was done by hand and crude mechanical calculators.
By fax, Phone mostly. And all the databases, electronic files, and everything else done on a computer today, was done with paper and ink.
Calculations in quantum computers are done in qbits.
Refurbished computers are different from used computers since they are tested before they are resold. The company that made them will test and inspect the computers to be sure they work to their professional standards. These tests may include the checking of motherboards and memory. But dents or scratches on the outside of the computer will not be repaired.
if you save the document before you turn off the computer then it will be saved into the computer memory but if not it will be lost. most computers ask you if you want to save the document before the computer shuts down if that happens all you have to do is click yes you want to save and your done as soon as you name the document.

Of course computers are important in advertising! you wouldn't be able to make advertisments if you didn't have computers. A lot of ads have computer generated effects or animation, this wouldn't be able to be done without computers.
computers are useful in class numurous ways for example: if you needed a report done and you didnt like your writing, you can do it on the computer
built with the same level of technology, analog computers are always faster but less accurate than digital computers. however as little significant work on analog computers has been done since the 1980s, they currently significantly lag behind digital computers in speed.
