The task not matched to the devices in Poland, not every use iPhones.

COURSE IS VERY INTERESTING BUT ASSIGNMENT CONTENT IS VERY DIFFICULT

Fairly good overview of events and technologies leading up to IoT.

the questions were too easy in my opinion. everything else is fine

内容详实而且深入浅出,基本涉及了网络基础、TCPIP、CS和PS和应用。

课件整体显得短小但精致实用，价格实惠，因此给予四星的评价。

Good background for non-experts but just an introductory course.

Good course to learn.Upgraded lot of information related to iot

Indeed it was a good course, but very less related to IoT.

NB-IoT is not discussed while getting upto here.

wonderful course, but weird quiz...

Good Course for Evolution of IoT

week 2 module 5 is interesting

Good review of the history.

the course was very good

Proper info provided

this course is good

it's very usefull

Interesting!!

very good

The mid portion is a little disconcerting; module 3 & 4. The lectures in no way corresponded to its quizzes and the questions asked were extremely confusing and difficult. Resorting to Google was really the only option as both lectures and slides were not really providing anything substantial. I spent hours at end trying the quizzes again and again, but to no avail, and even after getting the answer right, some of them did not make any sense. It certainly did not help that an additional 8 hours would have to be wasted just to try again. Overall, I do not recommend this module to those unfamiliar with the History of the Internet.

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.
