Networking for Sysadmins

Video Training

Networking is a complex but essential area of study for system administrators. This Learning Path covers the ways users can connect to a network; the concepts of switching, routing, and internetworking; end-to-end protocols; end-to-end data; network security; and everything else you need to know to keep a network functioning smoothly.


Basic system administration

Below are the video training courses included in this Learning Path.


Learning DNS

TCP/IP (Transmission Control Protocol / Internet Protocol) defines how devices connect to, and communicate through the Internet. This segment of your Learning Path explains how TCP/IP packages address, route, and deliver data over a network. You’ll use various network tools as you work through this hands-on course. By the time you’ve finished, you’ll have a thorough understanding of what a packet is and how it delivers data from point to point using TCP/IP.


Learning Network Technology and Security Fundamentals

Presented by David Miller 8 hours 17 minutes

Learn how to secure and protect information as it flows across an enterprise network. You’ll start by reviewing the Open Systems Interconnect (OSI) model, then jump into a review of TCP/IP before you move on to transmission media and technologies. You’ll get a look at the devices that make up the network infrastructure, including firewalls, routers, Virtual Private Networks (VPNs), client systems, and virtual machines. By the time you’ve finished this course, you will be fully capable of securing and protecting an enterprise network.
