Recently, I studied the design pattern. I used reflection when I learned about the abstractfactory of terrylee. By the way, I also studied the reflection mechanism of C. I collected some information on the Internet and my personal understanding for everyone to learn.In C #, we need to use reflection. First, we need to understand the relationships between several classes in the following namespace:System. Reflection namespace(1) appdomain: application domain, which can be understood as a logical

The output capacity of UPS refers to the product of the valid value U of the output voltage and the valid value I of the output current. Power Factor cos Phi refers to the ratio of active power P output by UPS to nominal view in power S, which can be expressed as cos Phi = P/S. Cos Phi is generally 0.8, UPS requires at least 0.8 of the load power factor, of course, the higher the power factor, the better, too low, it is too waste. When the power facto

Linux Load Average The average system load is defined as the average number of processes running in a queue during a specific time interval. If a process meets the following criteria, it will be in the run queue:-It is not in the result of waiting for I/O operation-It does not actively enter the waiting state (that is, "Wait" is not called) -not stopped (for example: waiting to be terminated)

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware. The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways: 1. If the server goes down, the load balancing system will stop requesting the server to go down and distrib
