The software environment in the computer field refers to the software system that runs on the computer hardware and drives the computer and its peripheral devices to achieve a certain purpose. It also refers to the running environment of software, such as XP, Linux, and peripheral software needed for software running. In addition, it also includes application software other than the target software.
Computer hardware maintenance principle
1, strengthen daily cleaning and maintenance, and clean it before specific testing.
If there are some problems in the environment, it will have a serious impact on computer hardware and related equipment, such as high temperature, stains, dust and so on. If the computer stays in this unfavorable environment for a long time, it is easy to cause hardware failure.
2, from simple to difficult, from general to special, step by step.
In the maintenance of computer hardware, we can start with simple faults to find the reasons, and then investigate step by step. In this process, we should also strictly follow the laws of mathematical statistics, first consider the high probability fault problem, that is, the universal or common fault problem, and then consider the low probability fault problem.
3. Consider the peripheral equipment of the computer first, and then check the peripheral equipment of the host.
In the specific maintenance, we should first consider the failure of external equipment and its possibility, and then consider the possibility of failure of the host after the detection of external equipment is completed, so as to conduct comprehensive detection and maintenance of the host.
