COMPUTER NETWORKING

Detailed explanation-1: -A public network is a type of network wherein anyone, namely the general public, has access and through it can connect to other networks or the Internet. This is in contrast to a private network, where restrictions and access rules are established in order to relegate access to a select few.

Detailed explanation-2: -The simplest way of explaining the Internet is to call it “the network of networks.” It’s the connection of computer networks around the world into one entity, so to speak. It’s not one big computer, but rather numerous networked computers connected together.

Detailed explanation-3: -A communications network that resides outside the organization’s firewall. The term typically refers to the Internet; however, there are military and financial networks that are public with regard to the firewall but not part of the global Internet. Contrast with private network.

Detailed explanation-4: -The Internet is a large cluster of networks linking millions of computers that reside in geographically dispersed locations. A device must get connected to a network before communicating over the internet. An internet service provider (ISP) provides the connection to other devices using cable wires or DSL lines.
