This isn't a question..
Computers are assembled in a factory.
Pre-assembled computers are factory made, usually by a known company like Dell, and come with the factory defaults for hardware and OS (Operating System). A computer would be custom built if you bought all of the parts separate and assembled the computer from scrap.
For example, Dell Computer uses a factory in Ireland to supply personal computers in Europe instead of exporting from Austin, Texas.
The fastest would be the most expensive computer right out of the factory, then overclock it to make it even faster, would probably be the fastest until the next computer was made from a factory to top that. Try Alienware computers.
The machines in a factory are remotely controlled by a computer. Computers are also used to manage the company's budget, doing online business, and writing correspondence.
The factory alarm is controlled by the engine and body computers. The engine computer is under the hood and the body computer is under the dash on the back side of the fuse panel.
There are step-by-step instructions on the Dell website that help to restore their computers to factory settings. Another way is reformatting your computer after backing up the information you still wish to keep.
No, not all computers come with DVD burners built into them. Although they are more common in computers today, they are sometimes an upgrade that must be purchased with a computer.
An arms factory is a place where weapons are produced.
In a factory. In China.
I think you question should be: "Where are computers made?" As far as I know, a number of famous computer factories are available in the world. As far as the computer factory in china is concerned, Taiwan and Guangzhou are two biggest ones in China.
A factory that produced ammunition, such as artillery shells, bombs, missiles is a munitions factory.
