2nd Note

Computer Networking!

Let's discuss what is network today!  (・∇・)

Simply put, a network a compilation of links. Maybe for some, computer network  = internet.

Even I thought the same thing before.
Actually computer network is  a collection of COMPUTERS and  other HARDWARE DEVICES that are CONNECTED together to share  hardware, software, and data as well as to communicate with one  another.

 For example a computer being connected to a printer, is also a  network.  

Now let me put some listing of 

Network Classification and Network components
