Computer Networks

The term Computer Networks to mean a collection or set of autonomous systems and computers interconnected to each other by the communication channel, medium, and network technologies.

Introduction of Computer Networks

Each of the past three centuries has been influenced via a single technology. The 18th century was the time period of the great unconsciousness systems assist the industrial revolution. The 19th century was the era of the steam engine. Throughout the 20th century, the key technology was information gathering, processing, and distribution.

The term “Computer Network” to mean a collection or set of autonomous systems and computers interconnected to each other by the communication channel, medium, and network technologies. Two or more nodes and computers systems are said to be interconnected if they are able to interchange the information with each other. These systems could be connected via an Ethernet wire, fiber optics, copper wire, microwaves, infrared and communication satellites. Network come in many shapes, size, forms and in different network topologies, as we will see later.

Basically, there are two terminologies connected to each other in a computer network, the first one is the internet and the second is the world wide web. Although it may sound strange to some people, neither the internet nor the world wide web is a computer network. The Internet is not a single network but a network of networks and the web is a distributed system that runs on top of the internet.

There is a lot of confusion between a computer network and a distributed system. The key difference is that in a distributed system, a set of unconventional system and computers become visible to its users as a single reasonable system. A usual, familiar and common example of a distributed system is the world wide web in which every single thing look like a document (web page), both distributed system and the computer networks need to move files around.
