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....

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Lots of historical references and terminology.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.

The quizzes were very demotivating for me as most of the questions were not covered in the lectures at all. That being said, the lecturer was lively and taught with enthusiasm.

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.

Quiz questions were very often unrelated or not found in the video lecture content. The early half of this course largely pertains to the History of IoT

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.

the content is inspiring but some of the content in quizzes are not stated in the lectures, making a hard time to search and check for the answers.

In most part the quizzes were asking topics not mentioned in videos or didn't give an extra lecture to make a read a prepare the quiz

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.

OK for the beginners as an introduction to IOT.

Course Videos and Quiz are hardly correlated.

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