Computer Networks

   According to Wikipedia, "A computer network, or simply a network is a collection of computers and network hardware interconnected by communication channels that allow sharing of resources and information."

   The "Computer Network" is a collection of autonomous computers interconnected by communication channels. Two or more computers are said to be interconnected if they are able to communicate each other. The communication channel may be optical fiber, copper wire, microwaves, satellites or any medium that allows communication. The networks may be in different shapes(Topology: Bus Topology, Ring Topology, Star Topology, Tree Topology, Mesh Topology), sizes(LAN, WAN, SAN, DAN, CAN), and forms.

   The Internet is known as Network of Networks. Internet is a global system of interconnected computer networks that use the standard Internet Protocol suit(TCP/IP).

   This is the basic knowledge of Computer Networks. We can discuss deep information about computer networks later.
