before any one of us ever touched a computer Networking Transmission Media

or was connected to the Internet, networking
meant going out to meet some friends and
having a conversation. The notes they took were the databases and servers. The
data people wanted to share were their dreams, curiosities and memories, and this
data was transmitted by writing in each other’s notebook and passing it from one
hand to another.
That sounds like an interesting time to live in, but it’s so different from today,
where everything is just a click away.
Then, humans took a giant leap and computers were developed for an individual
to work on his/her own machine. But as the usage increased, it was observed that
although computers offered computation power to their users, they could not suffice
all their needs because applications often demanded exchange of data between
several such users. Thus, the idea of linking two machines together that can share
information, emerged.
