Computers are indispensable in our work, study and life, and play a certain role in our life. The last time we were using the computer at home, we had an accident. There was a problem with the adapter of the computer. We were also very anxious because it was very convenient without the adapter . If the computer broke down, we would really change a computer. My friend told me the adapter of the computer. We can use adapter on other computers, so it’s much easier for us to use them. And we know that adapters are widely used, and they’re often used later.
