A computer server is also called as a server. A computer server is actually a computer which has the responsibility of running an application which is specific in nature. Sometimes if a computer server is fixed to run one particular application program, it may be named after that program. For example there may be many computer servers in the world, but few of them are named according to the tasks they perform. The applications of the server computers are divided between the computer servers. Computer servers are important not only to those who are in the field of networking but nowadays to everyone. The world of internet has made us so much involved in the world of interconnectivity and interdependence that the problems in the server computer of one company situated in one part of the world may have a direct effect on the people living in other parts of the world.

If the load on the computer is light, a computer server can run one program or one application separately. If this is not the situation, and the loading is not light, than you will need more than one computer servers. A server computer has a definite capacity till which it can bear the loading. If the loading becomes heavier than that, it is not possible for one single server computer to bear it.

There is another reason of having more than one computer servers at one time. If the burden on one of the computers is too much, it may cause damage to that computer. You must be ready to handle the situation if the server computer drops dead. This is the reason that if the loading is heavy, more than one computer serve as the computer server. These decisions are to be made keeping the situation and requirements in front of you.
