In a technical sense, a server is an instance of a computer program that accepts and responds to requests made by another program, known as a client. Less formally, any device that runs server software could be considered a server as well. Servers are used to manage network resources.
Diamond is stable at extreme pressures. To the top Conclusion Metamorphic rocks form from heat and pressure. Some of the minerals that make up those rocks also change properties as heat and pressure is applied. Polymorphs of minerals at different phases result and thus some minerals are only found in metamorphic rocks.ome of the minerals that make up those rocks also change properties as heat and pressure is applied.

On the basis of their origin, minerals may be divided into primary and secondary minerals. Minerals formed during solidi  cation of magma or lava are called primary minerals, and minerals formed by alteration of the primary minerals and by resyn-thesis and recrystallization during weathering are secondary miner als.
