What is the difference between the Internet and OSI reference model

Both the TCP/IP network model and the OSI Model create a reference model for computer networking. The OSI model is widely used to teach students as was created in the mindset of a reference book. The TCP/IP standards were created to provide guidance to people actually implementing a networking technology and was created in the mindset of a service manual. Much like the answer to the question of why was the internet created, the answer to why do we need the OSI model depends on who you ask. Here at ComputerGuru.net try to explain the basics of the OSI model as it relates to understanding basic computer networking.

The Internet and the TCP/IP family of protocols evolved separately from the OSI model. Often you find teachers, and websites, making direct comparison of the different models. Don't get too hung up on drawing direct comparisons between the two models. Our discussion here on the two networking reference models is address some commonly asked questions, and give some historical perspective as to how the models have evolved.

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.

Learning basic computer and networking technology

Woman working late on computerWelcome to the Guru42 Universe. Your journey to learning basic computer and networking technology concepts starts here at ComputerGuru.Net

Learning computer networking can be intimidating, like learning a foreign language, so many similar sounding words and phrases, and acronyms everywhere.

Many people attack their understanding of a computer concept in the context of using a dictionary to find the meaning of a word they don't understand. It would be difficult to learn a foreign language simply by using a dictionary as your tool.

Likewise, it is difficult to learn technology concepts simply by looking up specific definitions. We organize the material in sections that can be read like a chapter in a book by topics, rather than simply a list of definitions like a dictionary.Since 1998, ComputerGuru.net has attempted to provide self help and tutorials for learning basic computer and networking technology concepts, maintaining the theme, "Geek Speak Made Simple."

We continue to receive positive feedback from all over the world about our technology websites as we attempt to presented material more from a personal "lessons learned" perspective than a text book perspective.
