As we can see from the history there was a huge try to achieve the communication between people . The signals of smoke , the sounds of the drum , the fire were some of the basic ways for the transfer of a message in a era years ago . But these ways of communication was neither accurate nor has the certainty of the success . Also the transfer speed of the information was small , the size of the information tiny and the security of the communication was almost absence .

The need for networks appears for the first time when Graham Bell set in use the telephone . He was talking with a friend of his with a single line , but later when he wanted to talk to another friend of his he needed to use another line to connect his phone and the phone of his friend . So imagine that he has X friends , he would need X(X-1)/2 lines and X-1 phones , that was impossible so the need of networks come up . The network first developed for the need of the voi

TOKEN BUS . This protocol is complicated and requires the logical topology to be ring ( note not the physical topology but the logical one ) , and we use it in the bus networks .

In our days the most common networks are these that use the client / server computing environment .
