The server is a kind of the computer or a system which will provide the resources and the data with the services or the programs to the other computers and it is also known as the clients over the network. In t he theory the computers share the resources with client machines they are also considered as the iSeries server which is included with the web servers too and also the mail servers and sometimes the virtual servers too .
The systems:
The individual system will woks as the provider of the resources and use them from the system which is needed at the same time. The device can be either the server or the client and it may be the same at both times. The oldest version are the main frames or the minicomputers .The minicomputers are very much smaller to the main frame computers hence it is given the name. With the advancement of the technology it has ended up becoming to be larger and larger than the desktop computers. The servers initially where connected to the clients and they are considered as the dumb terminals and the actual work use to happen in the server.
The server are now considered to be the most powerful computes which are connected and the network will see the less powerful client in the computers . This kind of the architecture is considered to be the client server model in which both the client and the server posses the computer power and the major process will be done with the server. With the advancement of the technology the vertical servers are increased and the entire thing can be done with a single hardware server which can be done. The cloud computing is the birth of the virtual server and now a days it is runner by the third party hardware across the world and on the internet. This servers can be used as the mail servers and the they can be only assigned with the single work at a time .The servers are like they can perform many tasks or the multitasks at time like file printing storing a file and accepting of the print job and send the information to the network attached printer .
The client computer plays the main role of the executing the program and the server take the information and process it and does the work the server can take multiple commands at a time from any number of the client computers.
Summing up:
The server is a kind of the computer or a system which will provide the resources and the data with the services or the programs to the other computers and it is also known as the clients over the network.
