please give me a answer for my question:
what are the software and hardware requirement for build the network for 50 student in the university?
* basically 50 computes etc.
* if we can use you tube,we want headset etc.
Too generic of a question. Your actual requirements will greatly affect your design. One you answer the question at a detail level of what services you want your network to provide you have solved the vast majority of your problem.
But if you had say 48 computers all in one room you could buy a single 48 port switch that also has a couple of uplink port and hook it to a internet router. And if this happens to be your requirement then this is your solution
