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....

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.

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.

Content is interesting however there seems to be a lot of quizzes with inappropriate questions that are not taught. This is better in module 6 where the questions were answerable by viewing the teaching materials.

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.

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.

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.
