After running for a period of time, the LAN Based on Windows NT4.0 finds that the whole network runs slowly: running the office automation system and the WWW homepage in the Access Board is obviously slower than before, especially accessing the internal homepage.
A. Disconnection during testing
After confirming that there is no transmission problem, you can use the ping command to test and find that not only is it broken when you ping the intern
network. However, as the number of computers in the network increases, the number of broadcast packets will increase dramatically. When the number of broadcast packets reaches 30%, the transmission efficiency of the network will decrease obviously. When the NIC or network device is damaged, the broadcast packet will be sent continuously, causing the broadcast storm and paralyzing the network communication. Therefore, when the network equipment hardware failure will also cause slow speed. When y
problem, you can look at it in detail, with each row, column, and every 3x3 square containing 1-9 of these nine digits.
Examples:
Answer:
The Input subject contains multiple sets of tests, separated by a blank line between each group. Each set of tests gives you a 9*9 matrix, separated by a single space for the two elements that are adjacent to the same line. 1-9 represents the completed number of the position, and the question mark (?) indicates the number you want to fill in.

Sometimes, when the interface is tested, often need to rely on external interface environment, but in the actual development, especially in the agile development model, many times depending on the external interface environment may be impassability or not completed, this time can not be carried out in a timely manner end-to-end testing, the need to test the pile is very important. in my previous article, I have introduced the use of Third-party tools

Performance testing, load testing, stress testing What's the difference? Performance testing (or antisymmetric user concurrency performance testing), load testing, strength testing, and capacity testing are some of the areas of performance testing, but concepts can easily be confused. Here are a few concepts to introduce.
Performance test (performance Test): typically collects all the performance related

operation.
Depending on the time and resource characteristics of the product, the efficiency test can include different types of tests, such as performance tests (performance test), load tests (loading test), and stress tests (Stress test). These three types of efficiency tests, not only have different emphases on the

White box tests or white-box tests (White-box testing or Glass-box testing) are tested through the source code of the program without using the user interface. This type of test needs to be revised from the code syntax to find flaws or errors in algorithms, ov

In general, in order to determine the probability of making a mistake from the statistical results of samples (sample), we use statistical methods developed by statisticians to perform statistical verification.
