Basic computer networking explained in simple terms

A basic understanding of the concepts of computer networkingWhether you are a business manager learning the language of technology to better communicate with IT staff, or just beginning your IT career, don't overlook a basic understanding of computer networking.

What is computer networking?

The simplest definition of a computer network is a group of computers that are able to communicate with one another and share a resource. A computer network is a collection of hardware and software that enables a group of devices to communicate and provides users with access to shared resources such as data, files, programs, and operations.

In simplest terms, a computer network is created to share. In teaching computer networking I often commented that if you find someone who didn't like to use the computer network, they probably had a personal issue with the concept of sharing.

We live in a world of data and information. We love to share data and information. All that data and information gets from my house to your house thanks to the concepts of computer networking. We need computer networking to build the vehicles that transport data and information.

Basic network concepts and the OSI model explained in simple terms

An introduction to learning computer networking technologyIn this chapter of the journey to learn computer networking technology we explain the OSI Reference Model in simple terms, and expand on the different layers of the OSI model.

The OSI model defines the basic building blocks of computer networking, and is an essential part of a complete understanding of modern TCI/IP networks. The theoretical OSI Reference Model is the creation of the European based International Organization for Standardization (ISO), an independent, non-governmental membership organization that creates standards in numerous areas of technology and industry.

Why is the OSI Reference Model important?

An understanding of the concepts of the OSI Reference Model is absolutely necessary for someone learning the role of the Network Administrator or the System Administrator. The OSI model is important because many certification tests use it to determine your understanding of computer networking concepts.

The Open Systems Interconnection Reference Model (OSI Reference Model or OSI Model) was originally created as the basis for designing a universal set of protocols called the OSI Protocol Suite. This suite never achieved widespread success, but the model became a very useful tool for both education and development. The model defines a set of layers and a number of concepts for their use that make understanding networks easier.
