What are the computer maintenance apprentices recruited now?

At first, I may follow the maintenance master to repair the computer and help you install the system and software. On the hardware, you only need to see which component is broken and change it, for example, if the memory is broken, change the memory, so what the hardware teaches you is to check which component is broken. It's almost like being a repairman in the computer market. More in-depth is the maintenance of hardware parts, such as repairing the motherboard when the computer motherboard is broken and repairing the hard disk when the hard disk is broken. This requires you to see the company that has these repairs, and the basic repairs are just these things. I wish you an early study.
