| What are the types of web load testers? Posted: 09 Jun 2012 03:17 AM PDT What are the types of web load testers?Several Web load tests are textured to find out how a website or web application performs under various levels of usage, from the expected normal level to the predicted peak volume of traffic. There has also been said to be performance testing, reliability testing and volume testing. This type of testing is sometimes separated into three types. Load testing 1.0 is now largely obsolete. Load testing involves testing your server performance to see how many users it can cope with, but does not really give any useful information from the user perspective; for example, does a high load slow down the loading of the website? Website Load testing 1.5 uses the same methods as load testing 1.0, but it makes good use of Cloud based resources to run the tests. Then it is able to provide more information about your website's loads, being a good way to reduce costs. Website load testing 2.0 also looks at how a user will experience your website, sporting functions such as comparing a selection of internet browsers; this is to see if they have an effect on the load. Website Load testing 2.0 also uses Cloud computing resources, so is cost effective and extremely affordable. Although the terms load testing and performance testing are frequently used interchangeably, there are actually differences in their definitions. Load testing is normally defined as how much traffic the website is able to cope with, while performance testing looks at the speed of the website under different amounts of usage. Performance testing, then, is useful for looking at how a user will be affected by heavy website traffic. Different people working in the industry have varying opinions on the exact definitions of these terms. There is also no clear difference between what is load testing and what is stress testing (stress testing involves increasing the traffic until the website or software is no longer able to function, resulting in an error message). Although the benefits of carrying out web load testing are very clear (increased performance, greater speeds and thereby an increased level of business), there is no real agreement between software testers regarding the goals of load testing. It is a non-functional type of test, which means it looks purely at the amount of users that the system can deal with, not whether the website actually functions correctly. Several web load testing is now executed online, utilizing Cloud computing resources. This frees up the software testers to execute other tests, such as examining the website functions as it is expected to do.

| The Working Principles Of An Automotive Camera Module Alignment Posted: 08 Jun 2012 05:00 AM PDT The Working Principles Of An Automotive Camera Module AlignmentVehicle manufacturers and mechanics continue to make many changes with the aim of raising the safety levels on the roads. Automotive camera module alignment has been one of the introductions and has seen a very huge drop in terms of accident numbers. There are cameras that are placed strategically on the vehicle. The cameras usually give a view of sights that are hard for the driver to catch which include rear, side and sometimes front view. A monitor on the dashboard usually displays everything that the cameras capture. Drivers can opt to view from each camera one at a time or a screen split view of them all. Also included in the cameras is an infrared night vision feature. This feature becomes useful when it is dark because it becomes very hard to differentiate what you see from the actual thing. When active, the night vision clears out the dark aspect in the transmission and gives the driver such a good view. Highly responsive sensors are also used in the system. The sensors detect and warn when pedestrians and other vehicles are too close to the vehicle. It is only this way that drivers can avoid bumping into other vehicles and hitting pedestrians who are out sight of the bare eyes. The system also automatically takes over control of the vehicle for situations that run out of hand. Such situations are when a driver cannot be able to avoid an accident no matter how hard he or she tries. The car is then veered automatically back to safety, instantly braked or airbags pulled out. An analog video recorder is also included for saving all what the cameras capture. Should an accident take place then the police pull out all the saved videos and check to see what caused it. New vehicle buyers are advised to buy ones that have an automotive camera module alignment and those that do not have should plan on having one installed.
