[MUSIC] Smart Devices. In this module, we will focus on smart device specifications first and then go over all the details of smart devices. Which we will focus on smartphones and smart watches. Beginning with smartphones, we will focus on two device types. One is the Samsung Galaxy Note8 and the other one is the iPhone X. In these devices, we will focus on all the specific modules that are included inside that make them perform so outstandingly. First, when this was released and their manufacturer. The manufacturer for Galaxy Note8 is Samsung and it was released on August 2017. For the iPhone X, the manufacturer is Apple and this was released on September 2017. So a mere one month difference is all that distinguishes these two. Looking into the platform units that are used in smartphones, we will first begin with the most important module which is the chipset. The chipset contains the majority of the functions that the smart device has to use. In other words, it controls the overall communication. As well as the Wi-Fi Bluetooth networking interfaces. In addition, it does a majority of the processing that enables the smartphone to operate. So therefore, the chipsets play a significant role of the smartphones. For a Samsung Galaxy Note8, it uses the Qualcomm MSM8998, Snapdragon 835 chipset. In addition, there's a Samsung Exynos 8895 Octa chipset that could be used as well. For an iPhone X, it uses the Apple A11 Bionic. I know that you're thinking you need to know much more about these modules. And of course in this lecture, I will include further details. The second most important module on a smartphone is the CPU. It interfaces with all device components on the smartphone. Of course it will interface with the chipset to receive operations and ask it to do things. And also it will work with the graphics processing unit. Which is the row below and it will work together to get all the functionality coordinated for the smartphone itself. The CPU for Galaxy Note8 is an octa-core device. This means that it has eight cores. It has four cores which run at 2.35 GHz Kryo and also it has four cores which run at 1.9 GHz Kryo. Or, you can use an octa-core, which has four 2.3 GHz, and also four 1.7 GHz cores. Either way, you have eight cores that you will be using. Further details about the octa-core and the components will be explained pretty soon in following lectures. For iPhone X, you have hexa-core. That means that it has six cores. Two are Monsoon, and four are Mistral. What does this mean? Of course, I'll explain this later. The GPU is the next module we need to focus on. For Galaxy Note8, it's an Adreno 540 or a Mali-G71 MP20. For iPhone X, it uses the Apple GPU, which is a three-core graphics unit. We now look into display, camera, and additional features. The types of the display are Super AMOLED for Galaxy Note8, and for iPhone X it's OLED. The meaning of this, of course, I will explain in detail later. The display size is 6.3 inches for Galaxy Note8 and 5.8 inches for iPhone X. The resolution for Galaxy Note8 is 1440 by 2960 pixels for Galaxy Note8. And 1125 by 2436 pixels for the iPhone X. Protection wise of the display. For Galaxy Note8, it uses a Corning Gorilla Glass 5. And for iPhone X, it uses scratch resistant glass and it has the feature of oleophobic coating. What does Corning Gorilla Glass mean? Also, what does oleophobic coating mean? Of course, I will talk about the details of this in the following lecture. Then for the camera, it has a dual 12 MP for the Galaxy Note8. And for iPhone X, it'll use a Dual 12 MP as well. So, the primary camera. This is a camera on the backside of your smartphone. The one that you use for selfies, taking pictures of yourself, is a secondary one. And you can see the resolution right here. For the Galaxy Note8, it's an 8 MP one, for iPhone X it's a 7 MP one. Additional features include GPS. GPS is your positioning system that tells you your longitude and latitude, where you are. And this is critical, because a lot of the applications that are conducted on a smartphone are location based services, LBS. For the Galaxy Note8, it uses A-GPS, GLONASS, BDS, GALILEO. And for iPhone X, it uses A-GPS, GLONASS, GALILEO, and QZSS. What are the details of these? What do these GPS modules mean? Of course, I will explain this later. Looking into the battery of the two devices, the units are both in milli-Ampere hour, mAh, as listed in your left-side bottom corner. The battery types are both lithium ion. And lithium ion batteries with different capacities are used in these smartphones. For the Galaxy Note8, it's a 3300 milli-Ampere hour one, for the iPhone X, it is a 2716 milli-Ampere hour battery. In addition in the following lectures, I will talk about the details of wireless charging which is a critical feature for a smartphones nowadays. And therefore I will talk about the standards and what's going on in there. The next thing of the feature that we need to focus on is waterproof. Also, really, it is dustproof and waterproof. You will see that it has the identification of IP, two numbers and certified. What does that mean? I will of course explain the details of this very soon. For the Galaxy Note8, it has an IP68 certified. For the iPhone X, it is IP67 certified. Now let's talk about Smart Watches. I'm going to compare the Gear S3 as well as the Apple Watch Series 3. The Gear S3 is from Samsung and was released over a year ago in August of 2016. The Apple Watch series S3 was released in September of 2017. The platform, first we look into the operating system. Gear S3 is a Tizen-based wearable OS 2.3.2. And for the Apple Watch Series 3, it's a watchOS 4.0 from Apple. The chipset, for Gear 3, is an Exynos 7270. And for the Apple Watch Series 3, it's an Apple S3. For the CPU, for Gear S3 it is a Dual-core 1.0 GHz module, and for the Apple Watch Series 3, it is a Dual-core CPU as well. Looking into the display and other features. For the Gear S3, the size of the display is 1.3 inches. For the Apple Watch Series 3, it is 1.65 inches. The resolution of the display is a 360 by 360 pixel one for Gear S3. And for the Apple Watch Series 3, it is a 390 by 312 pixel. For Gear S3, the battery is a lithium ion 380 milli-Ampere hour one and also for the Apple Watch Series 3, it is a lithium ion 273 milli-Ampere hour battery. In addition, I will talk about the wireless charging, which will be a major feature for smart watches as well. Additional features include sensors. For the Gear S3, it includes a accelerometer, as well as gyro, heart rate, and barometer. For the Apple Watch Series 3, it includes the same sensor types. What does this mean? Well, of course I will talk about the details of these very soon. So please hang in there. Then, waterproof like I said, before I will talk about the details of IP certified standards very soon. But as we go into the details up here for the Gear S3. it is IP68 certified. For the Apple Watch Series 3, it is 50 meter that's about 164 feet water resistant. In the following lectures, I will talk about the details of what you saw in the tables of the specification for smart phones and smart watches. These are the references that I use, and I recommend them to you. Thank you.
