Focused a little too much on telephone history, though some was interesting. Perhaps spread out to other modules as short background material.

Would have preferred history/overview from Internet age with focus on various protocols/technologies that were introduced (IP, TCP, UDP, MQTT, Thread, Bluetooth, Zigbee

Module 6 made up for its more dynamic and more germane presentation. May be make it the 1st module, with other modules going back for a brief historical overview

Questions posted at the end of the module are way out of what's being taught in the course. The starting lecture are like going back in time and reading/learning about people who made difference in the world of networking. I am still not sure, how that helps you gain the strong foundation for IoT. I lost interest in the course the moment the questions went way out of sync with the lectures.

While the last module of this course is very interesting and kept with the specialization, the first 5 modules are a waste of time for the most part. Why would I want to learn about AT&T for two weeks? The amount of useful concepts introduced in the first 5 modules won't take more than 15 minutes if unnecessary things were removed.

This could probably be better broken into two one week courses "History of Phone Technology" and "Intro to IoT". Many reviewers say they bail out in first few lectures because content seems too far removed from IoT. I enjoyed the last few lectures with examples of IoT, but could have skipped the rest.

pace is slow. so many video in pieces, and lecturers keep saying like" we will look into more details later" or introduction again and again. I am studying module 2 now, all small lectures like 1 min or 2 mins, which is very shattered, repetitive and annoying.

In itself interesting content, structure was difficult to follow and the history - in my humble view - was going back too far into the past whereas more recent developments where only touched at the surface, quality of slides was poor.

This course helped me in getting introduced to the IOT space, it is very basic/preliminary in nature but helps in setting up stage/ context for acquiring more knowledge and hands on next sessions of the certification.

The teaching has been concise and to the point which is good but not so good for a few difficult topics. Also I've been experiencing video lag and audio stuttering while streaming the videos so there's that.

You must provide some materials because it some time get very irritating to answer your quizzes.I just wanted to know that why you guys wanted us to know about the history of AT&T and Bell labs.

Great instructors.

Lots of historical references and terminology. I would prefer more details about how stuff actually work - in simple layman's terms.

Looking forward to the second course.

This course is more of a history type of course which bores the learners. Course should be more of technological knowledge rather than the history of the technology.

It is informative, but there are many basics that were not covered well & there was a lot of information that was not that interesting (like too much history)

A lot of background information, most of which I was unfamiliar with. Kind of dragged on, but I think it'll ultimately be helpful in the specialization.

i feel this course start is somewhat bored because of teaching is not practical based and better follow udacity website tech for teaching interactively

The course is fine, but I would give the certificate out for free and charge for the ones that follow in the specialization as an incentive to enroll.

Interesting but very introductory. Don't expect to really learn something significant. Easy course. Accent is hard to understand.

Introductory, not completely relevant to my goals, could be ommitted. Nevertheless, I enjoyed the delivery of the instructor.

Not much useful if you want to learn about IOT but helpful if you want to learn historical development that lead to IOT

It's a very basic course with little technical overview. The history and story of emergence of internet is described.

Gooed clear presenters. Give a good idea of how connectivity works. Last module was a bit obvious (IoT applications)

While this course is well organized and descriptive, it barely touches the Internet of Things technologies.

This course is a refresher and provides a High Level overview of IoT and its history

as advertised

OK for the beginners as an introduction to IOT.

Course Videos and Quiz are hardly correlated.

Need to add more examples and explanation and question should not come from out of syllabus

Not really technical, but a good overview over the past years and even centuries...
