課程概述

It is hard to imagine life without your Smartphone – you have come to rely on it so much – for your work; to stay in touch with family and friends; to capture and share those special moments; to find your way around in a new neighborhood. Did you ever wonder how and when all this happened? Or how and when GPS sensors came to be in your cell phone? In this course, we will explore the convergence of multiple disciplines leading to todays’ Smartphones. You will learn about the birth and evolution of Telephony Networks, Broadcast Networks (TV and Radio) and Consumer Electronics. We will discuss the impact of Internet, (multimedia) content, smartphones and apps on everyday lives. We will then look at how this emerging platform called the Internet of Things – wherein billions and trillions of devices communicating with each other and “the cloud” – could enable unprecedented, innovative products and services. Take this course if you want to understand what great new advances in mobile-enabled products will be coming our way! Learning Goals: This course provides a core grounding in how science and technology have developed to enable the Internet of Things – in a way appropriate for any learner. For those interested in developing further hands-on expertise in designing and developing for the Internet of Things, this course will provide a context to the discoveries and converging technologies that will springboard the next round of innovations. After completing this course, you will be able to: 1. Compare how the telephone system works (that is, peer-to-peer networks) with how media delivery works (that is, broadcast/multicast networks). 2. Explain the tradeoffs between circuit switched networks (that is, dedicated resources) and packet switched networks (that is, shared resources). 3. Tell interesting stories about key innovations that transformed the communications, entertainment and consumer electronics industries. 4. Explain how email, YouTube, SMS, etc. work. 5. Find resources for those wishing to do more of a “deep-dive” into the above topics....

Majority of the quizzes were poorly designed as the content tested was barely covered in the video lectures. We should not have to google the answers ourselves, that isn't the point of testing. The video lectures were also rather unsatisfactory as they glossed over many of the terms introduced instead of giving a more thorough explanation.

The notes and lectures given are barely related to the tests/quiz questions. From what I see from the forum, many people have problems doing the quiz questions as well. This has indeed made learning harder and less efficient for the students and hence I suggest that you make this course be more informative and useful.

Many of the things tested in the quizzes at the end cannot be reasonably extrapolated from the lectures and only occasionally from the readings. It was very difficult for me to attain this certificate and I am now disincentivized from trying the other coursera modules if they all follow in the same vein.

most of course isn't useful for someone want to learn, it's all about history and the questions is so sick and aren't useful at all. the indian doctor can't explain or give you the information well beside his accent forcing you to read the subtitles to understand what he is saying

Arguably one of the worst online course that I've taken. Questions in the quiz weren't taught and little to no information were provided for learning in some later modules. For a beginner, it is extremely tedious to find the correct answers.

The Course material, with the exception of the last 2 modules, did not relate to the quiz question. Unless you are prepared to spend countless hours looking up the EXACT answer, most of the course is wasting your time.

Very poorly structured course. The lectures and content provided do not match with the quizzes. It can takes hours to Google search the correct answer which is unreasonable, especially with the limited attempts.

Seems like whoever prepared the quizzes from Week 2 onwards gave up following the lesson materials. As a result, I learnt nothing from the lecture and instead spent hours Googling in order to pass the quizzes.

Course content is completely irrelevant to the topics asked in the quiz. I had to rely mostly on discussion forums in order to help me get through this course. I would not recommend it at all.

Pathetic. Multiple quizzes with questions out of syllabus. I got tired looking for answers on google and cancelled the subscription. Free text questions don’t accept the correct answers too.

Boring, most of them are history. Don't worth it ! 1 week into the course, very boring. Not technical enough. The test basically asked people to remember things that are not useful !

Terrible module that expects you to learn everything yourself, no relation between graded assignments and course content, and quizzes are RIDDEN with spelling errors.

Absolute trash starting from Week 1 Module 2. Plenty of useless information that provide no benefits except for winning geeky obscure trivia games.

Big part of the course videos devoted to history of how the technology was developed, not much technical information about the technology itself.

Course advertised incorrectly. This course is more on the electronics and embedded systems end of IoT, as opposed to a high-level perspective.

創建者 YASH T

The assignments are not at all related to the course and not even 10% of the questions are from the video or reading content.

Nothing to do with IoT, misleading title and waste of time, apart from several incorrections in the novel narration.

Quizes are different that what lessons are! Too frustrating!
