3. The work content of the computer debugger is to carry out computer assembly and fault.Exclusion and hardware maintenance, and allocation to run the computer, that is, the operation skills of "saccuring" the computer and repairing the computer 1 Installation and debugging of the computer system 2 CMOS parameter settings 3 The use of diagnostic maintenance tool software 4 Config file and autoexec.

4. The work content of B2 debuggers usually includes troubleshooting and troubleshooting of cars, maintenance, adjustment and testing of cars, etc.

5. The test driver of the automobile factory is specifically responsible for the implementation of the test plan, the implementation of each test action and requirements according to the test specifications and the data recording, the wiring and disassembly of various sensors of the test vehicle, and the maintenance and custody of test instruments and equipment.

6. Hello. The installation you asked about should mean installation and debugging.Automobile industry: There is an overall shortage of talents. In the next five years, according to the level and needs of automobile development, the contradiction between the supply and demand of talents will not increase gradually, but will surge.
