About

If you’ve been in the Network Engineering career field for any small amount of time, then you’ve probably been frustrated at how difficult it was to find articles and videos that were reliable, thorough, and understandable. You found articles that were very entry level, that perhaps gave simple definitions but did not communicate enough to explain how technologies actually worked. You found articles that were overly detailed, that went into so much minutia that the original point would be lost. The intent of the blog and video channel is to bridge that gap — providing the happy, practical medium between overly simplistic and overly detailed. PracNet teaches in a manner that is accessible, easy to learn, and easy to pass on. By presenting complex technology simply, PracNet provides practical, immediately applicable, knowledge of the Network Engineering industry.

Video Description

In this video we provide a formal definition for Network "Protocols". We then briefly describe the functionality of the 8 most common networking protocols on the Internet: DNS, DHCP, HTTP, SSL, TLS, HTTPS, FTP, and SMTP. We follow that with a discussion on the four items which MUST be configured to achieve any sort of Internet connectivity. This is Lesson 6 of Module 1 of a Networking Fundamentals course. The first module will be released for free on Youtube and will teach anyone the very core of networking: How data moves through the Internet. === Networking Fundamentals - Module 1 === Lesson 1 - Network Devices Part 1: https://youtu.be/bj-Yfakjllc Part 2: https://youtu.be/H7-NR3Q3BeI Lesson 2 - OSI Model Part 1: https://youtu.be/LkolbURrtTs Part 2: https://youtu.be/0aGqGKrRE0g Lesson 3 - Everything Hosts to do speak on the Internet Part 1: https://youtu.be/gYN2qN11-wE Part 2: https://youtu.be/JI9Zm2tbUoE Lesson 4 - Everything Switches do to facilitate communication Part 1: https://youtu.be/AhOU2eOpmX0 Part 2: https://youtu.be/G7GyWjJtjNs Lesson 5 - Everything Routers do to facilitate communication Part 1: https://youtu.be/AzXys5kxpAM Part 2: https://youtu.be/Ep-x_6kggKA Part 3: https://youtu.be/zmxLg4jV0ts Lesson 6 - Networking Protocols - https://youtu.be/E5bSumTAHZE - ARP, FTP, SMTP, HTTP, SSL, TLS, HTTPS, DNS, DHCP - Four items MUST be configured for Internet Connectivity Lesson 7 - How Data moves through the Internet - https://youtu.be/YJGGYKAV4pA - Interview question: What happens when you type "site.com" into a web browser? --- If you enjoyed this content, then please tell one other person about this series.
