What is network?

                                     what is network?

   The network can be interconnected by connecting the computers overlaid to each other by sending  a file to another location or using a file in another location. It creates a communication between the two.

   Let's say that there are only songs and pictures on our  computer. Let's have videos on our friend's computer. If we need videos on his computer then we will pendrive those videos and see them on our computer. Similarly if our friend wants songs and photos, he will also pendrive through the copy and upload it to his computer.

   Without doing so, we can use data on both systems at any time if you connect to our computer and via a cable or a Bluetooth.  It is possible to connect as many computers as possible and use the data in it . The network is connected to two or more computers.

    A medium is required to connect to the network. The medium may be either wire medium or wireless medium. 

   The wire medium is the usual cable we use.

   For example copper cable,aluminum cable and telephone link cable can be called wire medium.

    The wireless medium is to connect the network using waves without cables.

    

For example radio waves, satellite and infrared waves.
