WEBVTT 1 00:00:00.120 --> 00:00:02.580 In this lesson, we're going to cover different 2 00:00:02.580 --> 00:00:05.010 motherboard connectors that you're going to come across 3 00:00:05.010 --> 00:00:07.800 and we're going to do this by looking at a typical motherboard. 4 00:00:07.800 --> 00:00:10.110 This particular motherboard has a form factor 5 00:00:10.110 --> 00:00:12.390 that supports an AM4 socket. 6 00:00:12.390 --> 00:00:14.730 This is known as a B550 motherboard 7 00:00:14.730 --> 00:00:17.730 from MSI and it's a gaming motherboard. 8 00:00:17.730 --> 00:00:19.440 Now first let's take a look here 9 00:00:19.440 --> 00:00:23.070 at the socket and I mentioned this is an AM4 socket. 10 00:00:23.070 --> 00:00:25.710 Now you'll notice AM4 is an AMD socket 11 00:00:25.710 --> 00:00:28.050 which means it is a pin grid array 12 00:00:28.050 --> 00:00:30.330 with a PGA or pin grid array, 13 00:00:30.330 --> 00:00:33.450 this means that we are going to take a CPU that has pins 14 00:00:33.450 --> 00:00:34.920 and place it into the holes 15 00:00:34.920 --> 00:00:37.080 that are sitting on this motherboard. 16 00:00:37.080 --> 00:00:38.850 If you're looking at a motherboard that supported 17 00:00:38.850 --> 00:00:42.630 an intel based LGA processor, we would see pins sticking up 18 00:00:42.630 --> 00:00:45.090 from this motherboard socket waiting to connect 19 00:00:45.090 --> 00:00:47.640 to the holes on the bottom of a processor. 20 00:00:47.640 --> 00:00:51.180 But again, because this is a PGA instead of an LGA 21 00:00:51.180 --> 00:00:53.040 this is an AM4 based socket 22 00:00:53.040 --> 00:00:55.467 and we are going to see the pins on the bottom of a processor 23 00:00:55.467 --> 00:00:57.390 and we would connect those into these holes 24 00:00:57.390 --> 00:00:58.980 we see here in the socket. 25 00:00:58.980 --> 00:01:00.810 Now just to the bottom of this socket, 26 00:01:00.810 --> 00:01:02.970 you'll see this little metal bar 27 00:01:02.970 --> 00:01:06.180 and this actually is the lever as part of the ZIF socket 28 00:01:06.180 --> 00:01:08.130 or a zero insertion force. 29 00:01:08.130 --> 00:01:09.990 To be able to insert our processor, 30 00:01:09.990 --> 00:01:11.970 we would lift that little lever up. 31 00:01:11.970 --> 00:01:14.340 You're going to see the holes open up a little bit more 32 00:01:14.340 --> 00:01:17.370 in the socket, we will then place our processor in, 33 00:01:17.370 --> 00:01:19.650 and then we will close that little lever back down 34 00:01:19.650 --> 00:01:22.650 to the board into the lock position as you see it now, 35 00:01:22.650 --> 00:01:24.870 and this would lock that into place. 36 00:01:24.870 --> 00:01:26.700 Next, we're going to move over to the right 37 00:01:26.700 --> 00:01:28.320 and we can see that there are four 38 00:01:28.320 --> 00:01:30.330 memory sockets right here. 39 00:01:30.330 --> 00:01:33.000 These are actually going to allow us to do either single, 40 00:01:33.000 --> 00:01:36.420 dual or quad channel memory with this particular motherboard 41 00:01:36.420 --> 00:01:38.430 and we'll talk more about that when we get to our section 42 00:01:38.430 --> 00:01:40.080 on system memory, 43 00:01:40.080 --> 00:01:42.660 but for now, you should be looking at these and going, oh 44 00:01:42.660 --> 00:01:44.970 those are really big sockets and there's four 45 00:01:44.970 --> 00:01:46.890 of them together or two of them together, 46 00:01:46.890 --> 00:01:49.320 and generally that's going to be the memory sockets 47 00:01:49.320 --> 00:01:51.240 for your particular motherboard. 48 00:01:51.240 --> 00:01:52.740 If we continue to the right, 49 00:01:52.740 --> 00:01:55.650 you'll see there is this large power connector socket 50 00:01:55.650 --> 00:01:58.500 right here and that is actually the main board power 51 00:01:58.500 --> 00:01:59.970 for this motherboard. 52 00:01:59.970 --> 00:02:01.590 This will connect a cable from here 53 00:02:01.590 --> 00:02:04.770 to our power supply and give us all the voltage we need 54 00:02:04.770 --> 00:02:07.350 for all the various components on this motherboard 55 00:02:07.350 --> 00:02:08.610 including the memory 56 00:02:08.610 --> 00:02:10.620 as well as all of our different expansion cards 57 00:02:10.620 --> 00:02:12.810 except for our processor socket. 58 00:02:12.810 --> 00:02:15.840 Now the processor requires a lot of power on its own, 59 00:02:15.840 --> 00:02:17.850 so we're actually going to power that 60 00:02:17.850 --> 00:02:21.120 using this port up here in the upper left corner. 61 00:02:21.120 --> 00:02:23.700 This is an eight pin CPU power socket 62 00:02:23.700 --> 00:02:25.530 and again this will connect directly 63 00:02:25.530 --> 00:02:28.140 to our power supply to provide us the proper voltage 64 00:02:28.140 --> 00:02:30.240 for the socket on this motherboard, 65 00:02:30.240 --> 00:02:32.610 which again is an AM4 socket. 66 00:02:32.610 --> 00:02:34.410 If we move over here towards the right, 67 00:02:34.410 --> 00:02:36.570 you'll see we have these four pin connectors, 68 00:02:36.570 --> 00:02:38.940 and as we go around, there's several of these on the board. 69 00:02:38.940 --> 00:02:41.550 There's this one here, which is for the CPU fan. 70 00:02:41.550 --> 00:02:43.350 This is another case fan. 71 00:02:43.350 --> 00:02:45.120 Over here we have another case fan, 72 00:02:45.120 --> 00:02:48.990 another case fan, down here we have another case fan, 73 00:02:48.990 --> 00:02:51.840 going over here on the bottom we have another case fan, 74 00:02:51.840 --> 00:02:53.910 and another one here on this bottom edge 75 00:02:53.910 --> 00:02:55.740 and there's lots of different case fans 76 00:02:55.740 --> 00:02:57.480 on this particular motherboard. 77 00:02:57.480 --> 00:03:00.360 Why? Because this is a gaming PC's motherboard 78 00:03:00.360 --> 00:03:03.270 and it can actually support up to six different case fans 79 00:03:03.270 --> 00:03:05.160 and each of those is going to get their power 80 00:03:05.160 --> 00:03:08.220 from this motherboard and the motherboard gets it again 81 00:03:08.220 --> 00:03:11.040 from that large 24 pin connector, 82 00:03:11.040 --> 00:03:12.810 that is the main board power supply. 83 00:03:12.810 --> 00:03:15.510 And so these other four pins that you see on the edge 84 00:03:15.510 --> 00:03:16.620 with the system fans, 85 00:03:16.620 --> 00:03:19.650 that's going to take the power from the 24 pin power supply, 86 00:03:19.650 --> 00:03:21.150 provide it through those four pins, 87 00:03:21.150 --> 00:03:23.610 and then directly into the case fans. 88 00:03:23.610 --> 00:03:25.050 Next as we move down, 89 00:03:25.050 --> 00:03:28.080 you can see we have this USB looking style slot, 90 00:03:28.080 --> 00:03:30.390 and this is actually a USB jumper 91 00:03:30.390 --> 00:03:31.950 to be able to connect to either our front 92 00:03:31.950 --> 00:03:34.470 or back panel connectors on our case 93 00:03:34.470 --> 00:03:37.260 that provide USB directly to our end user. 94 00:03:37.260 --> 00:03:38.220 As we move down, 95 00:03:38.220 --> 00:03:41.280 you'll see this black area with this port cluster. 96 00:03:41.280 --> 00:03:43.560 We'll revisit this when I look at the side of the board 97 00:03:43.560 --> 00:03:46.320 but essentially these are the six SATA ports 98 00:03:46.320 --> 00:03:49.440 that will connect our storage devices to this motherboard. 99 00:03:49.440 --> 00:03:52.530 As we continue to move along, we see another small connector 100 00:03:52.530 --> 00:03:55.170 here., this is a power LED connector that will actually 101 00:03:55.170 --> 00:03:58.530 light up green or red when this case is powered on. 102 00:03:58.530 --> 00:04:01.200 And then as we keep moving, we have another header connector 103 00:04:01.200 --> 00:04:03.780 for USB, and you'll see this is a different style. 104 00:04:03.780 --> 00:04:05.580 This one actually has a different pin out 105 00:04:05.580 --> 00:04:08.250 and this goes to a USB port cluster on the front 106 00:04:08.250 --> 00:04:11.280 of the case when you connect this motherboard to it. 107 00:04:11.280 --> 00:04:13.140 As we keep moving, we've got a couple more 108 00:04:13.140 --> 00:04:16.380 of these USB jumpers, we have the system fan over here, 109 00:04:16.380 --> 00:04:18.060 and then we're going to move all the way down here 110 00:04:18.060 --> 00:04:21.810 and we have this 10 pin area that actually has nine pins 111 00:04:21.810 --> 00:04:23.940 'cause one is missing and that is by design 112 00:04:23.940 --> 00:04:26.370 so you know which way to connect the adapter. 113 00:04:26.370 --> 00:04:28.890 This is going to be used for your audio cluster. 114 00:04:28.890 --> 00:04:31.080 If you have an audio jack on the front of your case, 115 00:04:31.080 --> 00:04:32.610 it has to be connected somewhere, 116 00:04:32.610 --> 00:04:34.740 and that's where this connects to. 117 00:04:34.740 --> 00:04:35.970 Then we're going to move up here 118 00:04:35.970 --> 00:04:38.250 and we have a couple of these expansion card slots. 119 00:04:38.250 --> 00:04:39.780 You'll see one right here 120 00:04:39.780 --> 00:04:43.950 which is actually a small PCIe x1 card slot, 121 00:04:43.950 --> 00:04:46.470 and we have another matching one right here. 122 00:04:46.470 --> 00:04:47.640 We're going to talk more about this 123 00:04:47.640 --> 00:04:49.920 as we go into expansion cards, but for right now 124 00:04:49.920 --> 00:04:52.050 the idea is these are places that we could put 125 00:04:52.050 --> 00:04:55.320 additional features or capabilities into the motherboard. 126 00:04:55.320 --> 00:04:57.450 For example, this motherboard actually 127 00:04:57.450 --> 00:04:59.640 on the rear port cluster, which we'll get to in a second 128 00:04:59.640 --> 00:05:01.680 has a network jack associated with it, 129 00:05:01.680 --> 00:05:05.190 but it only works with cat 6 or cat 7 cabling. 130 00:05:05.190 --> 00:05:06.990 If you wanted to connect a fiber cable directly 131 00:05:06.990 --> 00:05:08.970 to this motherboard, you couldn't do it, 132 00:05:08.970 --> 00:05:12.180 so you could put in a fiber network expansion card 133 00:05:12.180 --> 00:05:14.550 into this PCIe x1 slot 134 00:05:14.550 --> 00:05:16.920 and that would allow you to then connect the fiber connector 135 00:05:16.920 --> 00:05:18.570 to this motherboard. 136 00:05:18.570 --> 00:05:21.990 In addition to that, we have two PCIe x16 slots 137 00:05:21.990 --> 00:05:24.060 which are right here is the first one 138 00:05:24.060 --> 00:05:26.610 and the second one is here closer to the processor. 139 00:05:26.610 --> 00:05:28.950 Now you'll notice one is black and one is gray. 140 00:05:28.950 --> 00:05:30.240 What's the difference? 141 00:05:30.240 --> 00:05:33.900 Well, both of these support the same speed of PCIe x16 142 00:05:33.900 --> 00:05:35.670 which is the bus length and the size 143 00:05:35.670 --> 00:05:37.410 of the card that will go in there. 144 00:05:37.410 --> 00:05:41.820 Generally a PCI x16 is going to be used for graphics cards 145 00:05:41.820 --> 00:05:43.830 and the one that is closer to the processor 146 00:05:43.830 --> 00:05:47.370 in this silver color actually provides 75 watts 147 00:05:47.370 --> 00:05:49.050 of power through that. 148 00:05:49.050 --> 00:05:52.050 This is because it is a powered PCIe x16 149 00:05:52.050 --> 00:05:55.560 with additional power, whereas this lower one that is black 150 00:05:55.560 --> 00:05:56.850 this one does provide power 151 00:05:56.850 --> 00:05:59.820 but not nearly as much power as the top one. 152 00:05:59.820 --> 00:06:01.590 The top one is a little bit faster 153 00:06:01.590 --> 00:06:02.940 and it provides more power, 154 00:06:02.940 --> 00:06:04.710 but they are both the same form factor 155 00:06:04.710 --> 00:06:07.260 of being PCIe x16. 156 00:06:07.260 --> 00:06:08.760 We'll dive into that a little bit more 157 00:06:08.760 --> 00:06:11.430 as we start covering PCIe, their speeds, 158 00:06:11.430 --> 00:06:13.890 their power and things like that. 159 00:06:13.890 --> 00:06:16.050 The next thing you're going to see is this small connector 160 00:06:16.050 --> 00:06:16.980 down here. 161 00:06:16.980 --> 00:06:19.260 This is known as an M.2 connector. 162 00:06:19.260 --> 00:06:22.110 Now an M.2 connector is used for storage devices 163 00:06:22.110 --> 00:06:25.980 specifically M.2 based solid state devices. 164 00:06:25.980 --> 00:06:28.800 These are small little cards that look like a memory module 165 00:06:28.800 --> 00:06:32.010 and they'll be inserted in a flat manner into this socket 166 00:06:32.010 --> 00:06:35.460 and then screwed down using this retaining screw right here. 167 00:06:35.460 --> 00:06:37.890 We'll cover that more as we go into the storage section 168 00:06:37.890 --> 00:06:39.330 of this course. 169 00:06:39.330 --> 00:06:41.880 In addition to that, there is another M.2 slot 170 00:06:41.880 --> 00:06:44.010 hidden underneath this heat shield 171 00:06:44.010 --> 00:06:47.640 and this is a higher speed M.2 lightning gen four slot. 172 00:06:47.640 --> 00:06:50.550 It looks the exact same, but it has this heat sink 173 00:06:50.550 --> 00:06:53.370 on the top to remove excess heat from the storage device 174 00:06:53.370 --> 00:06:55.413 to allow for faster transfer speeds. 175 00:06:56.280 --> 00:06:58.650 The final thing I want to show you from this overhead view 176 00:06:58.650 --> 00:07:01.050 is this silver battery right here 177 00:07:01.050 --> 00:07:03.660 and this is called BAT1 on the motherboard 178 00:07:03.660 --> 00:07:06.240 but what it is is a CMOS battery. 179 00:07:06.240 --> 00:07:09.090 As we talked about the BIOS and UEFI later on, 180 00:07:09.090 --> 00:07:11.280 you'll learn we actually have a battery on our computer 181 00:07:11.280 --> 00:07:12.570 to retain our settings 182 00:07:12.570 --> 00:07:15.150 and that's exactly what we're seeing right here. 183 00:07:15.150 --> 00:07:17.670 That silver battery will last about three years 184 00:07:17.670 --> 00:07:19.770 and so if your computer starts losing its date 185 00:07:19.770 --> 00:07:22.771 and time and every time you power off the computer 186 00:07:22.771 --> 00:07:24.480 and you turn it on, it thinks it's a different day, 187 00:07:24.480 --> 00:07:26.010 you need to replace that battery 188 00:07:26.010 --> 00:07:27.270 and that's a good thing to keep in mind 189 00:07:27.270 --> 00:07:30.180 because all motherboards have this battery on them. 190 00:07:30.180 --> 00:07:32.070 Now the final thing I want to do is move over 191 00:07:32.070 --> 00:07:35.250 to some side views so we can see the edges of this board. 192 00:07:35.250 --> 00:07:36.510 As we move over here, 193 00:07:36.510 --> 00:07:38.640 you can see I twisted the board just a little bit 194 00:07:38.640 --> 00:07:41.100 so we can see those six SATA ports here 195 00:07:41.100 --> 00:07:42.990 on the right hand side of the board. 196 00:07:42.990 --> 00:07:45.930 Notice this is a seven pin SATA data cable 197 00:07:45.930 --> 00:07:47.883 and this is an L-shaped connector. 198 00:07:48.780 --> 00:07:52.140 In addition to the seven pin L-shaped data connector, 199 00:07:52.140 --> 00:07:55.020 each SATA device will need to get power and that will be 200 00:07:55.020 --> 00:07:57.390 from a L-shaped connector that looks similar to this 201 00:07:57.390 --> 00:07:59.670 but it's wider because it is 15 pins 202 00:07:59.670 --> 00:08:01.830 and it connects directly to the power supply 203 00:08:01.830 --> 00:08:03.630 not to the motherboard. 204 00:08:03.630 --> 00:08:06.390 As we move on, we're going to go and twist the board again 205 00:08:06.390 --> 00:08:09.270 and look at the left side of the board, and on this left 206 00:08:09.270 --> 00:08:12.270 or rear side of the board, you can see the port cluster. 207 00:08:12.270 --> 00:08:13.800 In addition to seeing it on the board, 208 00:08:13.800 --> 00:08:15.960 I've also taken a closeup directly of it, 209 00:08:15.960 --> 00:08:17.880 so we can go through these ports one more time 210 00:08:17.880 --> 00:08:21.060 as review from the cable section of our course. 211 00:08:21.060 --> 00:08:22.830 Now here on the backside of your computer, 212 00:08:22.830 --> 00:08:25.190 you're going to have this port cluster and on this motherboard, 213 00:08:25.190 --> 00:08:26.850 we have several different components 214 00:08:26.850 --> 00:08:29.940 including this first two here, which are both USB. 215 00:08:29.940 --> 00:08:31.830 Notice these have a USB logo 216 00:08:31.830 --> 00:08:34.680 but they do not say SS or super speed. 217 00:08:34.680 --> 00:08:37.920 This tells me that these are USB 2.0 compliant ports, 218 00:08:37.920 --> 00:08:39.990 and we can also see that because they are black 219 00:08:39.990 --> 00:08:43.350 instead of having a different color like red or blue. 220 00:08:43.350 --> 00:08:47.010 Generally you're going to see that USB 3 or SuperSpeed USB, 221 00:08:47.010 --> 00:08:49.830 is colored as blue and even higher speed ports 222 00:08:49.830 --> 00:08:51.453 will be colored as red. 223 00:08:52.290 --> 00:08:54.390 In addition to that, if we move over to the right, 224 00:08:54.390 --> 00:08:57.390 we are seeing what is called a PS/2 port. 225 00:08:57.390 --> 00:08:59.670 Now PS/2 is a very old standard 226 00:08:59.670 --> 00:09:01.590 and I'm actually kind of surprised to see this 227 00:09:01.590 --> 00:09:04.200 on a modern board like this B550, 228 00:09:04.200 --> 00:09:07.410 because no one really uses PS/2 connectors anymore. 229 00:09:07.410 --> 00:09:11.460 PS/2 connectors were very popular in the 1980s and 1990s 230 00:09:11.460 --> 00:09:13.800 but they fell out of favor in the early 2000s 231 00:09:13.800 --> 00:09:16.710 as USB was introduced and most people moved their mouse 232 00:09:16.710 --> 00:09:20.040 and keyboards connections into a USB slot instead. 233 00:09:20.040 --> 00:09:21.630 I'd be very surprised to find somebody 234 00:09:21.630 --> 00:09:22.980 using these these days, 235 00:09:22.980 --> 00:09:25.860 I was actually quite surprised to see it on this board. 236 00:09:25.860 --> 00:09:27.870 Next we have two graphics ports 237 00:09:27.870 --> 00:09:30.930 and we have integrated HDMI and display port. 238 00:09:30.930 --> 00:09:33.240 Now if you remember, HDMI and display port 239 00:09:33.240 --> 00:09:35.670 are both going to be used for graphics output, 240 00:09:35.670 --> 00:09:38.730 and this is actually an integrated card to this motherboard, 241 00:09:38.730 --> 00:09:41.280 so there is integrated graphics capability. 242 00:09:41.280 --> 00:09:43.680 Now for most gamers, they're not going to be happy using 243 00:09:43.680 --> 00:09:45.870 the integrated graphics card of this motherboard, 244 00:09:45.870 --> 00:09:50.040 and instead they're going to be using that PCIe x16 slot, 245 00:09:50.040 --> 00:09:52.710 especially that silver one closest to the processor 246 00:09:52.710 --> 00:09:54.600 to be able to put in a high quality 247 00:09:54.600 --> 00:09:56.430 and high performance graphics card. 248 00:09:56.430 --> 00:09:58.950 But if you don't have that and you want to save some money, 249 00:09:58.950 --> 00:10:02.220 you can use the ones integrated into this motherboard. 250 00:10:02.220 --> 00:10:05.310 Next we have two super speed USB three ports 251 00:10:05.310 --> 00:10:08.250 and these are type A ports, as you can tell by the rectangle 252 00:10:08.250 --> 00:10:10.530 with that blue plastic piece in there 253 00:10:10.530 --> 00:10:13.560 allowing us only to connect USB in one direction. 254 00:10:13.560 --> 00:10:14.820 As we move over to the right, 255 00:10:14.820 --> 00:10:16.290 you'll see we have a network jack, 256 00:10:16.290 --> 00:10:19.200 and this is called an RJ45 network jack, 257 00:10:19.200 --> 00:10:21.990 or most people just commonly refer to it as ethernet 258 00:10:21.990 --> 00:10:24.570 even though that is technically not accurate. 259 00:10:24.570 --> 00:10:28.050 Ethernet is a type of standard, it is not a type of cable. 260 00:10:28.050 --> 00:10:30.210 Instead this is what we call a UTP 261 00:10:30.210 --> 00:10:34.260 or STP cable or unshielded or shielded twisted pair cable, 262 00:10:34.260 --> 00:10:37.500 and it uses an RJ45 connector to terminate that. 263 00:10:37.500 --> 00:10:39.270 We can note that on this network jack, 264 00:10:39.270 --> 00:10:42.030 it is a 2.5 gigabits per second connection, 265 00:10:42.030 --> 00:10:44.760 because they notated that on the motherboard showing us 266 00:10:44.760 --> 00:10:46.500 that it is a very high speed connection, 267 00:10:46.500 --> 00:10:49.620 and supporting cat 6 and cat 7 cabling. 268 00:10:49.620 --> 00:10:53.100 Next, we have USB type C and they were even nice enough 269 00:10:53.100 --> 00:10:55.320 to write it for us on that jack. 270 00:10:55.320 --> 00:10:57.360 Now on the exam, if you get one of these things 271 00:10:57.360 --> 00:10:59.280 where you have to label parts of a motherboard 272 00:10:59.280 --> 00:11:00.870 or ports on a motherboard, 273 00:11:00.870 --> 00:11:03.060 you are not going to be given the names on these. 274 00:11:03.060 --> 00:11:04.650 They're going to hide those from you, 275 00:11:04.650 --> 00:11:09.060 but in this case we can see this is a super speed USB type C 276 00:11:09.060 --> 00:11:10.890 so it is USB 3, 277 00:11:10.890 --> 00:11:14.130 and you can see the number 10 there written next to the SS, 278 00:11:14.130 --> 00:11:16.890 and this tells us this is a 10 gigabit per second connection 279 00:11:16.890 --> 00:11:19.170 instead of the standard five gigabits per second connection 280 00:11:19.170 --> 00:11:21.000 that USB 3 comes with. 281 00:11:21.000 --> 00:11:23.610 And over to the right we have another USB port. 282 00:11:23.610 --> 00:11:24.870 This one is colored red 283 00:11:24.870 --> 00:11:27.390 to show us that it is a 10 gigabit per second port, 284 00:11:27.390 --> 00:11:29.370 and you also see that noted with the 10 285 00:11:29.370 --> 00:11:30.960 next to the SS symbol. 286 00:11:30.960 --> 00:11:34.290 Again, this is a type A connector being that large rectangle 287 00:11:34.290 --> 00:11:36.450 and shape instead of the type C to the left 288 00:11:36.450 --> 00:11:39.240 which is more of a small oval shape. 289 00:11:39.240 --> 00:11:41.760 Then as we move down, we have these two connectors 290 00:11:41.760 --> 00:11:43.350 that are gold in color. 291 00:11:43.350 --> 00:11:46.260 These are actually connectors for a wifi antenna, 292 00:11:46.260 --> 00:11:48.930 because this particular motherboard has an embedded wifi 293 00:11:48.930 --> 00:11:49.890 chip. 294 00:11:49.890 --> 00:11:51.510 Now, you can't see the antennas on here, 295 00:11:51.510 --> 00:11:53.040 because they haven't connected them yet, 296 00:11:53.040 --> 00:11:54.390 but that's what those are used for. 297 00:11:54.390 --> 00:11:55.770 It's going to use external antennas 298 00:11:55.770 --> 00:11:57.150 which are connected to ports. 299 00:11:57.150 --> 00:11:59.310 Under that, we have our audio cluster 300 00:11:59.310 --> 00:12:01.470 and our audio cluster is made up of two parts. 301 00:12:01.470 --> 00:12:04.560 The first part is what's known as S/PDIF 302 00:12:04.560 --> 00:12:07.350 and it says S/PDIF out, now that stands 303 00:12:07.350 --> 00:12:10.350 for the Sony Phillips Digital Interface Format, 304 00:12:10.350 --> 00:12:12.450 and this is a fiber optic cable connection 305 00:12:12.450 --> 00:12:15.540 that's used for audio output of the highest quality. 306 00:12:15.540 --> 00:12:17.850 Now, if you don't have that for your stereo system, 307 00:12:17.850 --> 00:12:20.400 you can instead use a 5.1 surround sound 308 00:12:20.400 --> 00:12:22.740 using the one eighth inch mini jacks there 309 00:12:22.740 --> 00:12:27.740 labeled RS-out, CS-out, Mic-in, L-out, and L- in 310 00:12:28.447 --> 00:12:30.270 to be able to connect a stereo system or speakers 311 00:12:30.270 --> 00:12:31.770 to this particular motherboard 312 00:12:31.770 --> 00:12:34.080 using its integrated sound card. 313 00:12:34.080 --> 00:12:35.160 So as you can see 314 00:12:35.160 --> 00:12:38.040 this motherboard has a ton of different capabilities 315 00:12:38.040 --> 00:12:40.800 and a lot of external ports that we can connect to. 316 00:12:40.800 --> 00:12:42.060 As you move through this course, 317 00:12:42.060 --> 00:12:43.890 it's important to understand each device, 318 00:12:43.890 --> 00:12:46.470 how it connects to this motherboard and how it gets power 319 00:12:46.470 --> 00:12:48.660 and data to and from these different devices, 320 00:12:48.660 --> 00:12:51.000 and what each device is going to be used for. 321 00:12:51.000 --> 00:12:53.430 In this lesson, I just wanted to show you a quick overview 322 00:12:53.430 --> 00:12:54.480 of the motherboard, 323 00:12:54.480 --> 00:12:57.810 so you can see these different ports and connectors visually 324 00:12:57.810 --> 00:12:59.730 and then identify what they are. 325 00:12:59.730 --> 00:13:01.680 For the exam it is important to understand 326 00:13:01.680 --> 00:13:03.300 these different ports and connectors 327 00:13:03.300 --> 00:13:05.580 and be able to label them on site. 328 00:13:05.580 --> 00:13:07.080 It would be very fair on exam day 329 00:13:07.080 --> 00:13:09.120 for CompTIA to give you a picture like this, 330 00:13:09.120 --> 00:13:13.909 and then several labels like CPU socket, memory socket, 331 00:13:13.909 --> 00:13:18.909 PCIe x1, PCIe x16, CPU power, main board power 332 00:13:20.040 --> 00:13:20.970 and things like that, 333 00:13:20.970 --> 00:13:24.000 and then have you drag them to the right place to label them 334 00:13:24.000 --> 00:13:26.550 on hotspots on a graphic like this. 335 00:13:26.550 --> 00:13:28.500 So keep that in mind as you're studying 336 00:13:28.500 --> 00:13:30.420 and as you're working with these different computers 337 00:13:30.420 --> 00:13:32.370 to be able to identify the different parts and pieces, 338 00:13:32.370 --> 00:13:35.223 and components visually as you're working on a system.
