How long does it take to learn how to repair and assemble computers and install monitoring systems?
Article Introduction:How long does it take to learn how to repair and assemble computers and install monitoring systems? It doesn’t take a long time to learn how to assemble a computer. It depends on the individual. A month or two is enough. However, it does take some time to know how to properly mix and match the computer. Because there are many types of computer hardware, you can only learn after you know how to assemble a computer, debug it, and match it. Monitoring is much simpler, basically one month is enough, and it takes about 3 to 6 months to be familiar with computer assembly technology. If you want to learn computer assembly and computer repair technology, is there any official website where you can learn systematically? Watching videos and books is useless for this. If you are interested, you can find a computer apprenticeship and try it out for a few months first, and then give it some video practice. It is an industry that relies on experience. Summary of learning and training? At the beginning, I should write down the content of my training, where I trained, how the training was, and whether I feel the training is meaningful.
