Free CCNA | JSON, XML, & YAML | Day 60 | CCNA 200-301 Complete Course

Welcome to Jeremy’s IT Lab. This is a free, complete course for the CCNA. If you like these videos, please subscribe to follow along with the series. Also, please like and leave a comment, and share the video to help spread this free series of videos. Thanks for your help. In this video we will look at JSON, XML, and YAML. These are known as data serialization

languages, or data serialization formats. These allow us to format or structure data in a standardized way so it can be communicated between applications. This is covered in exam topic 6.7, which says you must be able to interpret JSON encoded data. Note that it only mentions JSON, not XML or YAML. So, the majority of this video will focus on JSON,

but at the end I will take a bit of time to compare JSON to two other popular data serialization languages, XML and YAML. Here’s what we’ll cover in this video. First I’ll briefly introduce data serialization and why we need it. Then I’ll cover JSON. This will be the main part of this video,

and we’ll focus on how to interpret basic JSON-encoded data. Then I’ll briefly introduce XML and YAML, so you can compare and contrast them with JSON. However I won’t spend so much time on those two, since they’re not mentioned in the exam topics list. And make sure to watch until the end of the video for a bonus practice question from Boson Software’s

ExSim, the best practice exams for the CCNA. So, let’s take a look at what data serialization is. It is the process of converting data into a standardized format, or structure, that can be stored, for example in a file, or transmitted, for example over a network, and then be reconstructed later, perhaps by a different application.
