Legacy computer networks

Computer and Telephone networks have grown at an astounding rate over the last 20 years. As you probably already know, or learned in the earlier courses, TCP/IP and several variations of Ethernet now dominate the bulk of the world's networks. Plenty of other standards, mediums, and protocols existed before these staples emerged however, and they are the focus of this course. Just because the topics of this course are obsolete doesn´t mean you won't find them in the real world. Quite the contrary, there are bound to be pockets of these artifacts just waiting to be found at your next job, so familiarizing yourself with them is in your best interest. You'll likely need to know them too if you are considering trying to gain any of the industry certifications, which are detailed in a later course.
