Caching in name resolution stores previously resolved domain names and their corresponding IP addresses. This reduces the need to repeatedly query DNS servers, speeding up the name resolution process. When a domain name is requested, the resolver first checks its cache for the corresponding IP address before querying the DNS servers.

What is the name of the amount of useful energy you get from a system?

That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).


What is the name given to the effect of trapping energy in the atmosphere?

The name given to the effect of trapping energy in the atmosphere is the greenhouse effect. This occurs when certain gases in the Earth's atmosphere trap heat from the sun, leading to an increase in temperature on the planet.

What is the name of the machine of the force that prevents machines from operating at 100 percent efficiency?

The machine is called a governor. It regulates the speed and performance of machines to prevent them from operating beyond their design limits, protecting them from damage and ensuring stability.


Explain how much efficiency of an ideal machine compares with the efficiency of a real machine?

An ideal machine has, by definition, an efficiency of exactly 100%, which means that absolutely none of the energy it consumes is wasted when converted to power (energy per unit of time), hence the name "ideal". A real machine, however, will never reach an efficiency of 100%, as there will always be at least a tiny bit of energy that is lost to the environment. This is because it is practically impossible to create a perfectly closed system in which no energy can leak out. It is possible, however, to build very efficient systems and machines, although this depends on just how well they are made. Therefore, the efficiency of a real machine is quite variable, going easily from 10% to 98%, depending on its quality. A simple example is that of ordinary household voltage transformers, which generally have efficiencies of around 80%; and of high grade power plant transformers, which have efficiencies of around 98%.
