Learn about the five types of area networks.

An quick fundamental overview of layer two devices.   To learn more about this and similar topics, enroll in our exclusive Understanding Networking Fundamentals course.    

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2 of the OSI model.

While Apple has created many fine things, they were yet to be created themselves when Xerox PARC scientists created Media Access Control addresses. These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below:

The process of subnetting is both a mathematical process and a network design process. Mathematics drives how subnets are calculated, identified, and assigned. The network design and requirements of the organization drive how many subnets are needed and how many hosts an individual subnet needs to support. Binary basics and IPv4 address structure were covered in part one of this two-part paper.

The change we have been talking about for years is here: IT Departments are being torn apart and reassembled in new and interesting ways, as one by one companies make their move to the Cloud. As predicted, IT Pros are being asked to take on new and different roles and to be more involved in the business. In this session, we will look at some of these new roles; what’s working, what’s failing, who is succeeding and who has been left behind. Being an IT professional today is exciting as it is scary.
