How Does a Load Balancer Work? A load balancer is a reverse proxy. It presents a virtual IP address (VIP) representing the application to the client. The client connects to the VIP and the load balancer makes a determination through its algorithms to send the connection to a specific applica...

So how do surge protectors work and when you need them? And how do you know if the one you have is good quality? The main job of a surge protector system is to protect electronic devices from "surges." So if you're wondering what a surge protector does, the first question is, "...
A vacuum can have volume but does not have mass, and so, it would seem, a balloon with a vacuum inside should be lifted by the buoyancy of the air around it. This doesn't work, however, because of the force of surrounding air pressure. Air pressure doesn't crush an inflated balloon...
Distributed locking and pages using framesTomcat does not keep session instances in sync across the cluster. The implementation of such logic would be to much overhead and cause all kinds of problems. If your client accesses the same session simultanously using multiple requests, then the last re...
When the valve is closed, the ball completely obstructs the passage of the fluid. When the valve is in the on position, the ball does a quarter turn (90 degrees) and the fluid is allowed through a cavity inside the ball. These types of valves are in general more durable an...
Being involved does not mean doing a child's homework -- or correcting it. "Homework is a tool for teachers to know whether the child is learning or not," Steinberg says. "If you do the homework, you're not letting the teacher know what the child is learning." ...
The main job of a surge protector system is to protect electronic devices from "surges." So if you're wondering what a surge protector does, the first question is, "What are surges?" And then, "Why do electronics need to be protected from them?" ...
