(Do you still remember when you first saw a computer installed, JS plugged the CPU, memory, graphics card, etc. into the motherboard, and then took out its own key (or a random screw) from its pocket and lightly placed it on the side of the motherboard. Is it the case that the computer starts working with a single touch? Are you surprised? (I was surprised when I saw it for the first time)! Faced with a brand new motherboard, JS can always connect the dense jumpers on the motherboard within 1 or 2 minutes without reading any instructions. Do you think he is a master? Hehe, after reading today's article, you will feel that this is not worth mentioning, and as long as you memorize it a little, you can completely remember it, and you can get to the secret of getting all the jumpers on the motherboard without reading the manual.)
