Computer networks is defined as a collection of interconnected computers which uses a single technology for connection.
A distributed system is also the same as computer network but the main difference is that the whole collection of computers appears to its users as a single coherent system
Example :- World wide web

A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes.

An overlay network is a computer network that is built on top of another network.

In a computer network, a node can be anything that is capable of sending data or receiving data or even routing the data to the destination.

In a broadcast network, an information is sent to all station in a network whereas in a multicast network the data or information is sent to a group of stations in the network. In unicast network, information is sent to only one specific station.

A personal area network (PAN) is the interconnection of information technology devices within the range of an individual person, typically within a range of 10 meters.

A router[a] is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet.

A protocol stack refers to a group of protocols that are running concurrently that are employed for the implementation of network protocol suite.

A network congestion occurs when traffic in the network is more than the network could handle.

A virtual private network extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network.
