What is the difference between removing problems, testing and tuning?

Spend any amount of time of work or playing on computers and soon hear three words concerned about: problem removal , testing and tuning . While the first two are common enough, their meanings may seem blurred or even synonymous. In practice, each of these actions is different, although it is related. In many cases, the user's fault is to blame.

The first step in troubleshooting is to cover the foundations. Is software or hardware installed correctly? Is it correctly configured? Have you read the manual and follow all the instructions? Maybe you changed something in your system that caused the problem? Have you used this product all the time, or is it a new installation?

If it is a new installation, you can almost be sure that the problem lies in the installation process, especially in the case of hardware. The hardware requires a device driver (software file) that acts as a bridge or interface between hardware and operating system. If OVDevices fail, hardware cannot properly communicate with other system components. The device drivers may not be present or may have been installed in the wrong order with respect to the device.

If the problem lies in the hardware that has worked absolutely well, it can be the cause of corruption of the device driver. Reinstalling the driver can solve the problem. The updated driver can also make a trick. Other times, re -sending the component on the motherboard on the computer and the extraction of the components and reinstall to take care of the problem.

Hardware removal in Windows ™ operating systems is also available via device manager and Help menu. The yellow exclamation mark next to the component in the device manager indicates the problem.

software that starts to behave badly can also be damaged. Reinstall can sometimes helpI, but if the program began to act after installing a new, unrelated software, there may be a conflict between them. Firewally and antivirus programs are known for not playing together, and it is probably wise to stick to only one program in each of these categories unless you are an advanced user.

Problem removal generally usually includes reading manuals or help files, exceeding the basics to eliminate the user's error as a potential cause, and using a search engine to explore how the other problems have solved. If there is one thing you can always rely on as a end user, it is that someone has gone to your shoes before. The Internet community is very good about providing assistance and in most cases the answers can be found by Diligent searching for.

testing is the predecessor of tuning. Testing is usually the strength of programmers and advanced users and occurs when the product is new or updatesIt is necessary and should be carried out through its steps to eliminate potential problems. Testing identifies "errors" or imperfections in order to be corrected in the tuning process before [another] official release of the product. This "unofficial" edition is known as beta edition (eg 3.0 b ) and public volunteers are known as beta testers.

Beta testing is a valuable resource for software developers due to different participants in computer systems in combination with just the number of hours and scenarios in which the program is used. This will wash out unforeseen problems in a way that cannot be effectively achieved by means of domestic debuggers. The beta testing phase gives the authors a good idea of ​​the product's preparedness for the public domain.

Hardware is also tested beta, but because it is financially unbearable to provide free beta hardware for the public, hardware testing and tuning are normally done in the house. But beta products could be premieres and in somedistributed in a limited number to industry initiates at conferences such as Comdex.

Beta Software is specially available for testing and is not considered a stable edition. Beta Testers install beta software at their own risk and to help developers software to identify the source of the problem, they must provide a healthy amount of information when reporting error. The required data varies, but generally includes system specifications, beta versions and assembly, accurate conditions under which an error occurred, and the content of error messages.

tuning is forte programmers and developers and includes correcting the code itself to eliminate error or errors. Developers are trying to replicate beta reported errors of home systems to remove them.

While there are many types of tuning tools, a simple example is a tool that allows the programmer to monitor the program code while manipulating different commands and routines. OneThe basic approach is to simplify the code as much as possible in a suspicious problem place, while still replicating and narrowing the focus on potential problem lines. In fact, tuning is a complex process that requires different approaches based on factors, such as the complexity and length of the software code itself, and the language to which it is written.

tuning can be a tedious task, although some languages ​​are easier to match than others. For example, Java includes routines that process exceptions. The exemption error occurs when the program encounters a situation that must be solved before the program continues correctly. In this case, the built -in routine initiates "search" in various layers software code, searching for answers to the problem. If the correction cannot be found, a fatal exception is an error and the program will turn off. The resulting error message may include a memory address or some other cryptic data that does not help the user but can be valuable for tuning. Well written programs would not beLy to have fatal mistakes.

Older programming languages ​​such as c or are not so transparent and do not solve errors so effectively. Tuning programs written in these languages ​​can test the skills and patience of the tuning device.

Fortunately, for the end users, the software has already been tuned by the main shortcomings. For this reason, most of the problems that the end user encounters is within the scope of solving problems and can be corrected through the above. On these occasions that the end user encounters an error, it can go through problems to solve problems that can detect work up to BUG is fixed by a developer.

When applying for help on a web forum or a discussion group, make sure you do your homework in advance. Removing problems is time consuming, and people who voluntarily admit their help appreciate someone who tried to find answers. Ask a problem that was asked and answered repeatedly beforeHe gets friends and is considered a bad Netiquette.
