WEBVTT 00:00.330 --> 00:06.030 Hello, my name is Typhoon and today we are embarking on a journey to unravel the captivating world 00:06.030 --> 00:07.830 of XOR logic. 00:07.860 --> 00:12.990 This is a concept that adds a touch too much to the realm of computers. 00:12.990 --> 00:23.220 So a picture, a real tickle gate that requires not one but two unique keys unlock its secrets. 00:23.520 --> 00:25.890 That's the essence of logic. 00:25.890 --> 00:33.300 So get ready to delve into the inner workings of this logic gate and discover its remarkable role in 00:33.300 --> 00:34.620 the world of computing. 00:35.270 --> 00:44.630 So imagine X or logic as a magical gatekeeper that guards a hidden treasure room. 00:44.630 --> 00:49.040 So this gate has two key holes. 00:50.190 --> 00:50.730 Right. 00:50.880 --> 00:55.590 So each here designed for a different key. 00:55.980 --> 00:57.450 So let's write it. 00:57.480 --> 01:00.210 This has the two key holes. 01:00.750 --> 01:01.200 Let's. 01:01.880 --> 01:07.410 In front color and as I said, each designed for a different key. 01:07.430 --> 01:10.670 So, for example, a purple key. 01:10.670 --> 01:20.450 This is the this represents the zero and the gold or actually blue key represents the one. 01:22.090 --> 01:29.350 So to open the gate, you must insert the purple key into one keyhole. 01:29.350 --> 01:31.660 And this blue key. 01:32.570 --> 01:37.300 Entered the other, though only when this unique combination is met. 01:38.290 --> 01:42.920 So will the gate swing open revealing treasure within? 01:43.000 --> 01:53.250 So if you try to insert two silver keys or two gold keys, the gate remains fairly fastly locked, sealing 01:53.440 --> 01:55.070 its riches. 01:55.090 --> 01:56.080 So. 01:56.920 --> 01:58.750 In the realm of computers. 01:59.240 --> 02:09.220 XOR logic acts as a digital detective that poses a specific question Are these two things different? 02:09.250 --> 02:16.420 If the answer is yes, then it signifies that the two things are indeed distinct. 02:16.630 --> 02:17.950 The answer is no. 02:17.950 --> 02:21.010 Then the two things are the same. 02:21.010 --> 02:29.920 So XOR logic empowers computers to make decisions based on whatever the inputs provided are mutually 02:29.920 --> 02:32.110 exclusive from each other. 02:32.110 --> 02:35.800 So imagine you have a pair of enhancing light switches. 02:35.890 --> 02:38.080 In this case, let's actually write it. 02:38.080 --> 02:42.610 The switch A and switch B. 02:44.510 --> 02:48.470 Each capable of illuminating a room here. 02:48.470 --> 02:50.570 Let's also draw the house here. 02:55.040 --> 03:01.280 So only if one of them enhancing light switches is on while the other is off. 03:01.280 --> 03:08.300 So if a switch A is shining brightly, in this case it is one. 03:11.770 --> 03:14.680 And switch P is in darkness. 03:14.710 --> 03:16.390 In this case, it's zero. 03:16.420 --> 03:19.930 Or switch A is dimmed zero. 03:20.050 --> 03:24.040 And switch B is glowing one. 03:25.210 --> 03:27.880 The master switch turns on. 03:28.060 --> 03:41.710 However, if both switch A and switch B, share the same state, for example, both sharing a one year. 03:42.970 --> 03:43.630 Or both. 03:43.630 --> 03:44.950 Sharing zeros. 03:44.980 --> 03:48.040 The master switch remains off. 03:48.040 --> 03:48.580 Right. 03:48.580 --> 03:52.090 So it will be off in this state. 03:52.090 --> 03:54.790 So if both of these are. 03:55.710 --> 03:57.450 Equal to same. 03:57.480 --> 04:01.080 The master switch remains off. 04:01.080 --> 04:05.460 So consider mystical treasure chest guarded by a potent spell. 04:05.490 --> 04:10.020 To unlock this chest, you require two remarkable crystals. 04:10.110 --> 04:10.650 Crystal. 04:10.650 --> 04:10.800 A. 04:10.830 --> 04:11.790 And crystal B. 04:11.820 --> 04:20.430 As you place these radiant crystals on their designated pedestals, the chest springs open only when 04:20.430 --> 04:24.000 a crystal, a immense, a luminous glow. 04:24.030 --> 04:31.230 In this case, the crystal A will mount one, and crystal B remains in its natural state. 04:31.260 --> 04:39.030 Zero or when a crystal A actually let's actually use different colors for this so or a crystal here 04:39.030 --> 04:41.070 one as I said the. 04:42.070 --> 04:49.600 Kristel a emits a luminous glow in this case one and Kristel B remains in its natural state. 04:49.630 --> 04:50.530 Zero. 04:50.800 --> 04:58.840 Or when a crystal A rests calmly like zero and crystal B radiates its brilliance. 04:59.020 --> 05:04.540 And in this case, our treasure box will be open. 05:04.540 --> 05:14.590 So, yes, if both crystals share the same radiance or lack of the chest remains secretly locked, safeguarding 05:14.590 --> 05:15.700 its content. 05:15.700 --> 05:18.130 So in this case, if this is the. 05:19.690 --> 05:23.830 One here, one 1 or 0 zero. 05:23.860 --> 05:30.130 Then our chest will be locked and will not open in this case. 05:30.130 --> 05:38.770 And and or Logic finds its applications in an array of computer operations, such as ensuring the accuracy 05:38.770 --> 05:45.340 of data transmission and fortifying digital security through the cryptography, just like the intricate 05:45.340 --> 05:50.290 dance of is needed to unlock our mystical gate. 05:50.320 --> 05:57.790 So the XOR logic ensures specific conditions are met before granting access to valuable data. 05:58.540 --> 05:59.200 Formation. 05:59.200 --> 06:03.760 So there you have it, a comprehensive exploration of XOR logic. 06:03.790 --> 06:09.480 This is a captivating concept that infuses a sense of mystery to the world of computing. 06:09.490 --> 06:17.000 So think of it as puzzle, requiring the perfect pair of keys to unlock a hidden treasure. 06:17.020 --> 06:24.460 As you continue to venture forth, remember that XOR logic enables computers to make decisions based 06:24.460 --> 06:28.150 on the exclusive nature of two inputs. 06:28.150 --> 06:36.220 So keep your curiosity alive as your journey deeper into the enigmatic realm of logic. 06:36.520 --> 06:38.800 The ever evolving landscape of. 06:39.960 --> 06:41.670 And I'm waiting you in next lecture.
