What are the hardware and software failures What are the software failures

The software is in conflict with its Cita software when it is running, and it is incompatible with each other, which will cause software failures.

When debugging the user program or modifying the parameters, the operator deletes or changes the software content, which causes the software to be troubled. Insufficient battery voltage: The battery or battery circuit that supplies power to the RAM will be short-circuited or broken, and the contact will cause the RAM to not be able to maintain the voltage, so that the system will lose software and parameters.

Interference signal: Sometimes the fluctuation or interference pulse of the power supply will connect the bus of the CNC system, causing timing errors or stopping the operation of the CNC device.

The analysis of the causes of software failure is as follows: 1. Software incompatibilitySome software conflicts with other software and is incompatible with each other when running. If these two incompatible pieces of software are running at the same time, the running of the program may be paused and the tie-up system will crash severely.

A prime example of this is antivirus software. If there are multiple antivirus software in the system, it is easy to cause the system to run unstable2. Illegal operationIllegal operation is caused by improper human operation. For example, when uninstalling a program, you don't use the built-in uninstaller and delete the folder where the program is located, so that the program cannot be completely uninstalled, but will leave a large number of junk files to the system, which becomes a hidden danger to the system.

3. MisoperationMisoperation refers to the loss of important data in the hard disk caused by virus damage caused by the user's accidental deletion of useful system files or execution of formatting commands when using the computer. Computer viruses can cause unpredictable damage to the system, and some viruses can infect the executable files in the hard drive, making them unable to function normally; Some viruses will damage system files, causing the system to fail to boot normally; Other viruses can damage computer hardware, exposing users to greater losses. 4. Software with unreasonable software parameter settings, especially application software, is always used in a specific user environment.

If the environmental parameters set by the user cannot meet the user's environmental requirements, the user will often feel that there are some defects or failures in the software when using it. The document can be displayed normally during the process. But always a blank slate.

After inspection, it was found that the text system of the faulty computer was set up with the function of white characters on a blue background. I can't find anything abnormal when staring at the code (because it's a blue background), but the white paper can't show white words when printing, which leads to the occurrence of failures. x pairs.

Causes of occurrence:1Software is not compatible:

Some software is not compatible with other software when it is run. If these two programs are running at the same time, the system may be suspended, and in severe cases, the system may be crashed. A typical example is that there are multiple antivirus software in the system, and if you run them at the same time, it is easy to cause the computer to crash.

2.Illegal operation: Illegal operation is caused by improper operation by the user, such as not using the missing program when the software is missing, and directly deleting the folder where the program is located, which not only can not completely miss the program, but will leave a large number of junk files to the system, becoming a hidden danger of system failure.

3.Misoperation: Misoperation is when a user inadvertently deletes system files or executes a formatting command while using a computer. This can lead to loss of important data from the hard drive and even the inability to boot the computer.

4.Virus damage: Some computer viruses will infect the files in the hard disk, so that a program can not run normally; Some viruses will damage system files, causing the system to fail to boot normally; There are also viruses that can damage the hardware of the computer, causing users to suffer even greater losses.

2.Reinstall the application: If you have an error using the application, you can reinstall the application after it is completely unloaded.

Similarly, reinstalling the driver can also fix the malfunction of the computer part due to a driver error.

3.Take advantage of antivirus software: Some programs with lower versions (especially operating systems) are vulnerable and prone to errors when running. Therefore, if a program frequently makes errors while running, it can be solved by upgrading the version of the program.

4.Find missing files: If you are prompted that a system file cannot be found, you can extract the original file from the operating system's installation disc or from the correct computer to the appropriate system folder.

Listen to the start-up alarm sound to determine which hardware is the problem.

There is also the simplest and most effective way, which is the substitution method. No matter how high the master, the substitution method must also be used to troubleshoot the hardware.

A hardware failure usually refers to the failure of the motherboard, CPU or memory, and external devices.

Software failures are usually failures caused by incompatibilities or conflicts between the operating system or some software.

To put it simply, hardware failure is a fault that you can't repair, and you generally get after-sales replacement hardware; Software failures can be resolved by reinstalling the software or by other means.

"Computer hardware" is a collective term for all physical parts and equipment in an electronic computer system. A "computer hardware failure" is the failure of all physical components and equipment in an electronic computer system.

Software failures of computers" are non-physical failures.
