Weird “split”, I don’t agree with it, but sure, I’ll play along.
For manufacturing, it’s predominantly Asia. China, Taiwan, Korea and Japan are the largest manufacturers of computer components. But a good amount are still made in the US, particularly in Texas, and all over the world there are some other manufacturers.
For design and research, it’s predominantly Asia and western nations, again China, Taiwan, the United States and Japan are prominent, as well as a number of Western European nations such as the United Kingdom.
I really don’t think you know what you’re talking about, do you?
