WEBVTT 1 00:00:00.000 --> 00:00:00.900 [Instructor] In this lesson, 2 00:00:00.900 --> 00:00:03.420 we're going to talk about mobile device synchronization 3 00:00:03.420 --> 00:00:04.590 and how you can synchronize data 4 00:00:04.590 --> 00:00:07.140 from your various applications across devices 5 00:00:07.140 --> 00:00:08.730 or into the cloud. 6 00:00:08.730 --> 00:00:09.750 But before we do that, 7 00:00:09.750 --> 00:00:12.660 let's first talk about the two main OS' out there 8 00:00:12.660 --> 00:00:14.070 for mobile devices. 9 00:00:14.070 --> 00:00:16.620 These are Android and iOS. 10 00:00:16.620 --> 00:00:18.480 When you're dealing with mobile operating systems 11 00:00:18.480 --> 00:00:20.190 and tablets and smartphones today, 12 00:00:20.190 --> 00:00:23.460 there really are only two dominant players in this market. 13 00:00:23.460 --> 00:00:26.040 The first is the Android operating system. 14 00:00:26.040 --> 00:00:28.290 Android has taken a lot of market share 15 00:00:28.290 --> 00:00:30.420 because it offers an open-source code base 16 00:00:30.420 --> 00:00:33.600 instead of a closed-source or proprietary code base. 17 00:00:33.600 --> 00:00:36.450 Android has been sponsored and developed by Google. 18 00:00:36.450 --> 00:00:38.070 It has a very large distribution 19 00:00:38.070 --> 00:00:39.480 of the operating system code, 20 00:00:39.480 --> 00:00:42.300 and is widely available on smartphones and tablets, 21 00:00:42.300 --> 00:00:43.740 as well as other smart devices 22 00:00:43.740 --> 00:00:46.080 like network streaming TV set top boxes, 23 00:00:46.080 --> 00:00:48.930 and a myriad of other internet of things devices. 24 00:00:48.930 --> 00:00:50.340 Because of the open-source nature 25 00:00:50.340 --> 00:00:51.390 of the Android code base 26 00:00:51.390 --> 00:00:53.250 that makes up this operating system, 27 00:00:53.250 --> 00:00:55.620 each manufacturer of a tablet or smartphone 28 00:00:55.620 --> 00:00:56.700 can actually change the way 29 00:00:56.700 --> 00:00:58.410 the operating system looks and feels 30 00:00:58.410 --> 00:01:00.990 before implementing that on their devices. 31 00:01:00.990 --> 00:01:04.350 For example, if you look at an Amazon Kindle Fire tablet, 32 00:01:04.350 --> 00:01:05.310 they don't look anything 33 00:01:05.310 --> 00:01:07.080 like a normal Android tablet, 34 00:01:07.080 --> 00:01:08.790 but underneath them they're actually running 35 00:01:08.790 --> 00:01:10.230 the Android operating system, 36 00:01:10.230 --> 00:01:13.380 but they've done a customized interface on top of it. 37 00:01:13.380 --> 00:01:15.720 Because that operating system is open-source, 38 00:01:15.720 --> 00:01:18.300 manufactures can save considerable time and money 39 00:01:18.300 --> 00:01:20.610 by not having to reinvent their own operating system 40 00:01:20.610 --> 00:01:22.470 for their tablet devices or smartphones, 41 00:01:22.470 --> 00:01:25.800 and instead they can use Android as their baseline. 42 00:01:25.800 --> 00:01:29.520 Now, the other dominant mobile operating system is iOS. 43 00:01:29.520 --> 00:01:30.930 iOS was developed by Apple 44 00:01:30.930 --> 00:01:32.850 for use on their iPhones and iPads, 45 00:01:32.850 --> 00:01:35.880 but these days iOS is only used on iPhone, 46 00:01:35.880 --> 00:01:38.400 and the iPadOS, which is a variation of this, 47 00:01:38.400 --> 00:01:40.290 is used for their iPads. 48 00:01:40.290 --> 00:01:41.790 Now this operating system, 49 00:01:41.790 --> 00:01:44.040 which we're going to collectively call iOS, 50 00:01:44.040 --> 00:01:45.810 relies on closed-source code 51 00:01:45.810 --> 00:01:48.300 that was developed and sponsored by Apple. 52 00:01:48.300 --> 00:01:49.440 Because of the proprietary 53 00:01:49.440 --> 00:01:51.840 and closed nature of this operating system, 54 00:01:51.840 --> 00:01:54.420 the only people who can use it are Apple, 55 00:01:54.420 --> 00:01:56.610 because they own the intellectual property for it, 56 00:01:56.610 --> 00:01:58.590 and they only have licensed it for use 57 00:01:58.590 --> 00:02:00.990 on Apple hardware at this point. 58 00:02:00.990 --> 00:02:03.960 Now when I talk about open versus closed-source, 59 00:02:03.960 --> 00:02:05.220 this is an important distinction 60 00:02:05.220 --> 00:02:06.930 when we talk about software. 61 00:02:06.930 --> 00:02:09.780 When we talk about a system that is denoted as open-source, 62 00:02:09.780 --> 00:02:12.090 it means that the software and its original source code 63 00:02:12.090 --> 00:02:13.260 are freely available 64 00:02:13.260 --> 00:02:15.630 for any developer who wants to download it, 65 00:02:15.630 --> 00:02:18.540 modify it, and redistribute this code base. 66 00:02:18.540 --> 00:02:20.820 This allows manufacturers to utilize the code 67 00:02:20.820 --> 00:02:22.620 without having to pay a large licensing fee 68 00:02:22.620 --> 00:02:24.810 to the original software manufacturer. 69 00:02:24.810 --> 00:02:27.750 Additionally, they can modify the operating system or code 70 00:02:27.750 --> 00:02:29.520 to do whatever it is they wish with it, 71 00:02:29.520 --> 00:02:31.710 whether that's putting it on a smartphone, a tablet, 72 00:02:31.710 --> 00:02:33.480 or another smart device. 73 00:02:33.480 --> 00:02:36.540 Open-source software allows them to have a lot of creativity 74 00:02:36.540 --> 00:02:38.430 in the manufacturing of their devices, 75 00:02:38.430 --> 00:02:40.560 as well as the ability to have other people working 76 00:02:40.560 --> 00:02:42.240 to help create more applications 77 00:02:42.240 --> 00:02:44.400 for the operating system that they're using. 78 00:02:44.400 --> 00:02:45.420 This is one of the reasons 79 00:02:45.420 --> 00:02:46.860 that the Android operating system 80 00:02:46.860 --> 00:02:49.980 has grown so fast in popularity with manufacturers 81 00:02:49.980 --> 00:02:52.110 because they have a lower cost of services 82 00:02:52.110 --> 00:02:53.790 by using this open-source platform 83 00:02:53.790 --> 00:02:56.280 as their code base for their operating system. 84 00:02:56.280 --> 00:02:59.310 Now conversely, Apple's iOS falls under the category 85 00:02:59.310 --> 00:03:00.840 of closed-source. 86 00:03:00.840 --> 00:03:02.610 When you use closed-source software, 87 00:03:02.610 --> 00:03:05.400 you're usually going to be doing this with proprietary software 88 00:03:05.400 --> 00:03:07.110 and this computer software is licensed 89 00:03:07.110 --> 00:03:09.960 under the exclusive legal right of the copyright holder, 90 00:03:09.960 --> 00:03:11.250 in this case Apple, 91 00:03:11.250 --> 00:03:13.230 and they can license that to other people 92 00:03:13.230 --> 00:03:15.720 to use under their terms and conditions. 93 00:03:15.720 --> 00:03:18.600 Now, the licensee who is going to license his software 94 00:03:18.600 --> 00:03:20.460 will be restricted from other uses, 95 00:03:20.460 --> 00:03:22.800 so they're not allowed to modify it, share it, 96 00:03:22.800 --> 00:03:26.340 study it, redistribute it, or reverse-engineer the code. 97 00:03:26.340 --> 00:03:28.200 When you're dealing with closed-source software, 98 00:03:28.200 --> 00:03:30.030 all you're getting is the product, 99 00:03:30.030 --> 00:03:31.710 you don't get to see how it was actually created 100 00:03:31.710 --> 00:03:34.680 or the actual software code underlying it. 101 00:03:34.680 --> 00:03:38.070 I like to think about open versus closed software this way, 102 00:03:38.070 --> 00:03:41.130 let's say that you want to have a pie for dessert tonight, 103 00:03:41.130 --> 00:03:43.080 if you go to your local bakery to buy a pie, 104 00:03:43.080 --> 00:03:44.670 they're not going to give you the recipe, 105 00:03:44.670 --> 00:03:46.890 this is like closed-source software. 106 00:03:46.890 --> 00:03:48.120 You're going to pay for a pie, 107 00:03:48.120 --> 00:03:50.460 you can eat the pie, you can enjoy the pie, 108 00:03:50.460 --> 00:03:53.070 but you're not going to know how they made the pie. 109 00:03:53.070 --> 00:03:53.970 Now on the other hand, 110 00:03:53.970 --> 00:03:55.770 let's pretend you went to the grocery store 111 00:03:55.770 --> 00:03:57.210 and they only had apple pies, 112 00:03:57.210 --> 00:03:59.220 but you wanted a blueberry pie. 113 00:03:59.220 --> 00:04:02.310 Well, too bad that store only sells apple pies 114 00:04:02.310 --> 00:04:04.020 so you're going to have to eat that apple pie 115 00:04:04.020 --> 00:04:06.120 for dessert tonight instead of blueberry. 116 00:04:06.120 --> 00:04:07.590 This is because you have no method 117 00:04:07.590 --> 00:04:09.180 to change the recipe of the pie, 118 00:04:09.180 --> 00:04:11.580 because you don't know how that pie was made. 119 00:04:11.580 --> 00:04:13.140 Now let's compare this to going over 120 00:04:13.140 --> 00:04:15.360 to your friend's house and getting a pie from them. 121 00:04:15.360 --> 00:04:18.060 Now this might be more like an open-source solution, 122 00:04:18.060 --> 00:04:20.310 your friend, instead of giving you the apple pie, 123 00:04:20.310 --> 00:04:23.130 they might give you the recipe to make the pie yourself. 124 00:04:23.130 --> 00:04:23.963 This is what happens 125 00:04:23.963 --> 00:04:25.920 with the open-source software community. 126 00:04:25.920 --> 00:04:27.090 You can have the end product 127 00:04:27.090 --> 00:04:29.340 by simply downloading the Android operating system 128 00:04:29.340 --> 00:04:30.720 and use it as it exists, 129 00:04:30.720 --> 00:04:32.820 or in this case, you can go to your friend's house 130 00:04:32.820 --> 00:04:34.950 and take an apple pie they've made for you, 131 00:04:34.950 --> 00:04:37.320 or you can actually download the source code 132 00:04:37.320 --> 00:04:39.510 and remodify it for your own use. 133 00:04:39.510 --> 00:04:40.740 In the apple pie example, 134 00:04:40.740 --> 00:04:42.360 you got the recipe from your friend 135 00:04:42.360 --> 00:04:44.250 and you changed out the apples for blueberries 136 00:04:44.250 --> 00:04:46.650 so you can make the pie that you actually want to eat. 137 00:04:46.650 --> 00:04:48.540 This is the beauty of open-source, 138 00:04:48.540 --> 00:04:50.820 creativity and change can be included, 139 00:04:50.820 --> 00:04:53.040 whereas with closed-source or proprietary software, 140 00:04:53.040 --> 00:04:54.300 they can't. 141 00:04:54.300 --> 00:04:55.800 Now we've just finished a discussion 142 00:04:55.800 --> 00:04:57.720 of open-source versus closed-source, 143 00:04:57.720 --> 00:04:59.280 and while that's all valid, 144 00:04:59.280 --> 00:05:01.380 the end user rarely is going to be involved 145 00:05:01.380 --> 00:05:04.380 in developing the operating system or the code itself, 146 00:05:04.380 --> 00:05:07.410 instead, that end user simply wants to be able to buy, 147 00:05:07.410 --> 00:05:10.320 download, and use applications on their device. 148 00:05:10.320 --> 00:05:12.960 To get applications if you're using an Android device, 149 00:05:12.960 --> 00:05:15.270 you can get them from a couple of different places. 150 00:05:15.270 --> 00:05:17.130 First place is the official marketplace, 151 00:05:17.130 --> 00:05:19.140 known as the Google Play Store. 152 00:05:19.140 --> 00:05:20.850 This is by far the most widely used 153 00:05:20.850 --> 00:05:23.310 and easiest place to get new applications. 154 00:05:23.310 --> 00:05:24.630 But with Android, 155 00:05:24.630 --> 00:05:27.240 because we're dealing with an open-source operating system, 156 00:05:27.240 --> 00:05:28.410 you're not actually limited 157 00:05:28.410 --> 00:05:30.330 to just the Google Play official store, 158 00:05:30.330 --> 00:05:32.430 and instead, you can actually get your software 159 00:05:32.430 --> 00:05:35.340 or applications from a variety of different sources. 160 00:05:35.340 --> 00:05:38.089 For example, you can go to the Amazon Appstore, 161 00:05:38.089 --> 00:05:39.390 GetJar, SlideME, 162 00:05:39.390 --> 00:05:41.850 or numerous other third party application stores 163 00:05:41.850 --> 00:05:44.550 to download software onto your smartphone or tablet, 164 00:05:44.550 --> 00:05:46.890 if you're running the Android operating system. 165 00:05:46.890 --> 00:05:47.940 Apple on the other hand 166 00:05:47.940 --> 00:05:50.220 prefers to use a walled garden approach, 167 00:05:50.220 --> 00:05:53.850 and this means you can only get apps directly from Apple. 168 00:05:53.850 --> 00:05:55.860 Now this doesn't mean Apple's the only developer, 169 00:05:55.860 --> 00:05:58.800 but it means you can only get get apps from their app store 170 00:05:58.800 --> 00:06:00.630 which is called the App Store. 171 00:06:00.630 --> 00:06:03.540 Now, the App Store is an application on your iOS device 172 00:06:03.540 --> 00:06:05.010 that allows you to access a store, 173 00:06:05.010 --> 00:06:07.230 purchase, and download applications. 174 00:06:07.230 --> 00:06:08.640 Under the Apple terms of service, 175 00:06:08.640 --> 00:06:10.350 you're not allowed to download an application 176 00:06:10.350 --> 00:06:11.970 from anywhere else in the world, 177 00:06:11.970 --> 00:06:14.460 you can only do it from the App Store. 178 00:06:14.460 --> 00:06:17.160 Your iOS device will not allow outside applications 179 00:06:17.160 --> 00:06:18.780 to be installed on that device 180 00:06:18.780 --> 00:06:20.880 without first jail breaking that device, 181 00:06:20.880 --> 00:06:22.800 and since Apple Software is closed-source, 182 00:06:22.800 --> 00:06:25.560 the end user is required to accept the terms of service 183 00:06:25.560 --> 00:06:27.270 prior to being able to use the device, 184 00:06:27.270 --> 00:06:29.520 so they are now locked into the App Store 185 00:06:29.520 --> 00:06:31.620 when they want to download software. 186 00:06:31.620 --> 00:06:34.560 Now in both the Google Play Store and the Apple App Store, 187 00:06:34.560 --> 00:06:35.760 you're going to find applications 188 00:06:35.760 --> 00:06:37.740 from lots of different developers. 189 00:06:37.740 --> 00:06:40.080 Anyone can make an application for this software, 190 00:06:40.080 --> 00:06:42.420 but they have to get it approved and published 191 00:06:42.420 --> 00:06:44.640 into the app store for you to be able to download it 192 00:06:44.640 --> 00:06:46.682 and install it on your mobile device. 193 00:06:46.682 --> 00:06:49.320 To create an application for an iOS device, 194 00:06:49.320 --> 00:06:51.360 you're going to use the programming language Swift, 195 00:06:51.360 --> 00:06:52.650 and use Apple's Xcode, 196 00:06:52.650 --> 00:06:54.360 which is an integrated development environment 197 00:06:54.360 --> 00:06:57.180 to create the code that creates that application. 198 00:06:57.180 --> 00:06:59.880 On the other hand, if you want to create an app for Android, 199 00:06:59.880 --> 00:07:00.780 you're going to be writing this 200 00:07:00.780 --> 00:07:02.580 in the Java programming language, 201 00:07:02.580 --> 00:07:04.170 and you'll be using Android Studio 202 00:07:04.170 --> 00:07:05.940 as the integrated development environment, 203 00:07:05.940 --> 00:07:07.920 and this can operate on Linux, Windows 204 00:07:07.920 --> 00:07:09.840 and macOS systems. 205 00:07:09.840 --> 00:07:12.510 Now once your applications are installed on a device, 206 00:07:12.510 --> 00:07:14.130 you need a way to synchronize the data 207 00:07:14.130 --> 00:07:16.080 that's being held by those applications 208 00:07:16.080 --> 00:07:19.620 across multiple devices, including laptops, desktops, 209 00:07:19.620 --> 00:07:21.600 smartphones, and tablets. 210 00:07:21.600 --> 00:07:23.760 Now one of the easiest ways to synchronize your data 211 00:07:23.760 --> 00:07:25.260 across multiple devices 212 00:07:25.260 --> 00:07:28.770 is to use a shared account across a cloud based network. 213 00:07:28.770 --> 00:07:31.320 There are three main providers in this area, 214 00:07:31.320 --> 00:07:33.840 Microsoft, Google, and Apple. 215 00:07:33.840 --> 00:07:37.620 Microsoft uses a product known as Microsoft 365, 216 00:07:37.620 --> 00:07:39.000 this gives you the ability to have 217 00:07:39.000 --> 00:07:40.470 office productivity software, 218 00:07:40.470 --> 00:07:42.420 as well as a large amount of storage space 219 00:07:42.420 --> 00:07:45.570 in the cloud under what is known as OneDrive. 220 00:07:45.570 --> 00:07:48.210 Users of Microsoft 365 will normally get 221 00:07:48.210 --> 00:07:49.950 an email account associated with it 222 00:07:49.950 --> 00:07:52.620 using the generic domain of outlook.com, 223 00:07:52.620 --> 00:07:55.470 or by having a registered third party domain 224 00:07:55.470 --> 00:07:57.210 such as your own company's domain name 225 00:07:57.210 --> 00:08:00.540 if your company uses 365 at the enterprise level, 226 00:08:00.540 --> 00:08:01.410 for example, 227 00:08:01.410 --> 00:08:04.380 if I decide to use Microsoft 365 for my company, 228 00:08:04.380 --> 00:08:05.700 we would then have email addresses 229 00:08:05.700 --> 00:08:07.650 of @diontraining.com, 230 00:08:07.650 --> 00:08:10.500 and it would be hosted and provided by the Microsoft servers 231 00:08:10.500 --> 00:08:12.720 using the 365 service. 232 00:08:12.720 --> 00:08:15.420 The second option we have is using Google Workspaces 233 00:08:15.420 --> 00:08:16.860 provided by Google. 234 00:08:16.860 --> 00:08:19.620 Now Google Workspaces requires a Google account, 235 00:08:19.620 --> 00:08:21.300 meaning a Gmail account, 236 00:08:21.300 --> 00:08:23.550 or having an enterprise account with Google 237 00:08:23.550 --> 00:08:25.050 and your own domain. 238 00:08:25.050 --> 00:08:27.360 My company actually uses Google Workspace 239 00:08:27.360 --> 00:08:29.310 for all of our productivity software. 240 00:08:29.310 --> 00:08:31.260 This gives us the ability to have Google Docs, 241 00:08:31.260 --> 00:08:35.010 Sheets, Slides, and Google Drive for cloud based storage, 242 00:08:35.010 --> 00:08:37.140 as well as providing email for all of our team members 243 00:08:37.140 --> 00:08:38.430 at Dion Training. 244 00:08:38.430 --> 00:08:40.800 When you email us at deontraining.com, 245 00:08:40.800 --> 00:08:42.750 it's actually going through a Google server, 246 00:08:42.750 --> 00:08:44.820 and they're the ones who are hosting our email for us 247 00:08:44.820 --> 00:08:46.710 as part of Google Workspace. 248 00:08:46.710 --> 00:08:49.260 And the third option we have is Apple's option, 249 00:08:49.260 --> 00:08:50.970 this is known as iCloud. 250 00:08:50.970 --> 00:08:53.070 Now if you get an Apple account with iCloud, 251 00:08:53.070 --> 00:08:57.510 your email is going to be @icloud.com, or @me.com. 252 00:08:57.510 --> 00:09:00.060 This is a free service that anybody can sign up for, 253 00:09:00.060 --> 00:09:02.460 and there is a free storage level tier on iCloud 254 00:09:02.460 --> 00:09:03.600 when you sign up for this, 255 00:09:03.600 --> 00:09:05.310 and this service works exceptionally well 256 00:09:05.310 --> 00:09:09.090 if you're using an iPhone or an iPad as your mobile device. 257 00:09:09.090 --> 00:09:10.500 Now in addition to the free level, 258 00:09:10.500 --> 00:09:12.750 there is a paid tier you can have with iCloud as well 259 00:09:12.750 --> 00:09:15.720 that gives you additional storage capacity in the cloud. 260 00:09:15.720 --> 00:09:17.460 Now when you configure your device, 261 00:09:17.460 --> 00:09:18.480 you're going to choose which 262 00:09:18.480 --> 00:09:20.160 of these three services you're going to use, 263 00:09:20.160 --> 00:09:22.080 or some other option out there, 264 00:09:22.080 --> 00:09:24.690 and this will allow you to sync up information and data 265 00:09:24.690 --> 00:09:26.640 from your devices to other devices 266 00:09:26.640 --> 00:09:28.530 across multiple mobile devices 267 00:09:28.530 --> 00:09:30.150 and your desktops and laptops 268 00:09:30.150 --> 00:09:31.923 using these cloud based services.
