hi, i know nothing abt networking stuff and i m having my own silly ideas abt it. but as far as i understand every network has a main pc which is called server, which controls other pcs, right? other pcs connected to the server can access data from the server. the server has a hard drive where softwares are installed and once the network is set up other pcs (with no hard drive on them as i understand at the moment or may be i m misunderstood) can use the same software. for example in a uni library there are 50+ pcs all connected to a server and any one who wants to use a particular application such as microsoft word can do so with a username and a password from any one of the 50 pcs on that network. what i mean here is there is no need to install microsoft word or any other application on any of the 50 pcs in order to use them. am i right in my understanding of the network concept as stated above? if not plz let me know how exactly it works in simple terms i will be gr8ful. i m hoping that a simple explanation will do me a gr8 favour. thanks a lot.
