1 00:00:00,380 --> 00:00:05,720 Hello, my name is Tayfun, and in this lecture we are going to learn about the and logic. 2 00:00:05,750 --> 00:00:10,840 So today we are embarking on a journey to unravel the fascinating world of logic. 3 00:00:10,850 --> 00:00:16,720 And this is a concept that brings a touch of teamwork to the realm of computers. 4 00:00:16,730 --> 00:00:23,750 So imagine a magical lock that only opens when two specific keys are used together. 5 00:00:23,780 --> 00:00:26,400 That's the heart of an and logic. 6 00:00:26,420 --> 00:00:33,350 So now we will dive into the intricacies of this logic gate and uncover its vital role. 7 00:00:33,380 --> 00:00:34,250 The realm of. 8 00:00:35,300 --> 00:00:45,470 So think of and logic as a pair of these steel gates, each requiring a key to open. 9 00:00:46,620 --> 00:00:49,810 But these keys come in two colors. 10 00:00:49,830 --> 00:00:54,480 The one is silver in this case, right? 11 00:00:54,480 --> 00:00:56,700 It My driving skills is not that good. 12 00:00:56,730 --> 00:01:00,960 But I will try this as hard as I can, so. 13 00:01:02,550 --> 00:01:03,000 Here. 14 00:01:05,790 --> 00:01:10,230 So here we have the silver key. 15 00:01:11,460 --> 00:01:17,700 And we throw the here and we also have this gold key. 16 00:01:21,850 --> 00:01:23,710 So this is our keys here. 17 00:01:23,860 --> 00:01:31,570 So here to unlock these gates, you need a silver key for one gate. 18 00:01:32,320 --> 00:01:36,220 And the gold key for the other, right. 19 00:01:36,370 --> 00:01:44,080 So only when both keys are inserted simultaneously will the gate swing open, granting access. 20 00:01:44,080 --> 00:01:51,770 So if either key is missing or if both keys are the same color, the gates remain tightly closed. 21 00:01:51,790 --> 00:01:59,860 So in the world of computers and logic acts as a digital partnership that ask a specific question. 22 00:02:00,810 --> 00:02:11,910 So the basically this and logic asks just want this this very simple and specific question are. 23 00:02:29,750 --> 00:02:33,200 Are both things true? 24 00:02:37,010 --> 00:02:38,770 Write this. 25 00:02:38,780 --> 00:02:41,640 Ask just this question here. 26 00:02:41,660 --> 00:02:42,440 That's it. 27 00:02:42,470 --> 00:02:48,820 So if the answer is yes, then it signifies that the both things are true. 28 00:02:49,220 --> 00:02:53,550 If the answer is no, then at least one of the things is false. 29 00:02:53,570 --> 00:03:01,240 So and logic empowers the computers to make decisions based on the joint validity of the two conditions. 30 00:03:01,250 --> 00:03:04,130 So imagine you have a two loyal guards. 31 00:03:04,160 --> 00:03:08,720 This is a guard A and guard B, each of with lantern in their hands. 32 00:03:08,720 --> 00:03:12,080 They hold a power to illuminate a path. 33 00:03:12,230 --> 00:03:19,640 Introduce the logic to the scenario, and logic acts as a grand illuminator, lighting the way only 34 00:03:19,640 --> 00:03:23,690 when both guards have their lanterns ablaze. 35 00:03:23,780 --> 00:03:33,020 So if a guard a lantern shines and a guard B lantern casts its glow, the grand illuminator beams brightly. 36 00:03:33,050 --> 00:03:39,690 However, if a either guard or guard B has their lantern unlit, in this case, it's zero. 37 00:03:39,960 --> 00:03:48,930 But lit is glowing is one, then the illuminator remains dim, so we can also have a consider mythical 38 00:03:48,930 --> 00:03:51,690 bridge guarded by a vigilant sphinx. 39 00:03:51,870 --> 00:03:55,920 To cross the bridge, you need to answer the two riddles correctly. 40 00:03:56,010 --> 00:04:00,390 Riddle A and riddle B Only when both riddles are answered accurately. 41 00:04:00,390 --> 00:04:01,320 You can. 42 00:04:02,040 --> 00:04:03,660 Then you can proceed, right? 43 00:04:03,930 --> 00:04:13,020 So if either A or riddle B is answered incorrectly, the bridge remains inaccessible and the Sphinx 44 00:04:13,020 --> 00:04:14,510 watchful gaze persists. 45 00:04:14,520 --> 00:04:20,820 So and Logic finds its application in various computer scenarios, such as ensuring the fulfillment 46 00:04:20,820 --> 00:04:24,060 of multiple conditions before performing an actions. 47 00:04:24,060 --> 00:04:29,100 And just like the synchronized keys required to unlock our mystical gates. 48 00:04:29,100 --> 00:04:36,720 So add logic ensures that both conditions are met before granting access or triggering a specific route. 49 00:04:36,930 --> 00:04:45,390 So here it's actually just a bit we will be dealing with is so I will write some diagram here so you 50 00:04:45,390 --> 00:04:49,080 will understand better and here. 51 00:04:49,320 --> 00:04:50,880 So we will need to. 52 00:04:52,330 --> 00:04:54,940 Actually, we don't need this here, so. 53 00:04:57,240 --> 00:04:58,080 Just need to. 54 00:05:00,950 --> 00:05:03,460 The brush size here and that's it. 55 00:05:03,640 --> 00:05:11,560 So here we will delete this brush off and here we will create some diagram. 56 00:05:11,740 --> 00:05:13,450 For illustrative purposes. 57 00:05:13,540 --> 00:05:14,800 So one. 58 00:05:15,560 --> 00:05:16,220 But let's. 59 00:05:16,700 --> 00:05:18,980 So this is one. 60 00:05:19,580 --> 00:05:20,210 You. 61 00:05:21,030 --> 00:05:22,430 Re here. 62 00:05:22,440 --> 00:05:24,740 So this is our first two and. 63 00:05:25,320 --> 00:05:25,750 Right. 64 00:05:26,390 --> 00:05:26,540 And. 65 00:05:28,250 --> 00:05:29,330 Again here. 66 00:05:34,700 --> 00:05:37,100 And again, we will add another here. 67 00:05:37,100 --> 00:05:39,240 Actually, we don't need to add here. 68 00:05:40,170 --> 00:05:40,770 Does this. 69 00:05:44,920 --> 00:05:45,770 And that's it. 70 00:05:45,790 --> 00:05:47,710 So now what we're going to do is. 71 00:05:48,420 --> 00:05:50,010 This is our A. 72 00:05:50,770 --> 00:05:51,670 Different color. 73 00:05:52,480 --> 00:05:53,650 Uh, a. 74 00:05:54,520 --> 00:05:55,240 Be. 75 00:05:55,390 --> 00:05:57,970 And this is our output, right? 76 00:06:04,520 --> 00:06:14,900 So here, if our A is true and B is true as well, then our output will be one. 77 00:06:15,140 --> 00:06:21,290 If our A is zero and B is zero as well, then our output will be one again. 78 00:06:21,770 --> 00:06:27,740 But if our A is one and B is zero, our output will be zero. 79 00:06:27,740 --> 00:06:34,280 And if our A is zero and B is one, our output will be zero again. 80 00:06:34,280 --> 00:06:40,970 So as we explained here in this cases, our output is set. 81 00:06:41,860 --> 00:06:53,430 Here again, sad, but in these cases, these are output as this one output here, these are happy. 82 00:06:53,440 --> 00:06:54,070 Right. 83 00:06:54,160 --> 00:06:57,100 And that's it with our and logic. 84 00:06:57,280 --> 00:07:01,810 There you have it and extensive exploration of and the logic. 85 00:07:01,810 --> 00:07:07,720 So this is a captivating concept that adds a sense of collaboration to the world of computing. 86 00:07:07,810 --> 00:07:14,710 Think of it as a harmonious partnership between two keys need to unlock a set of gates. 87 00:07:14,710 --> 00:07:21,430 As you delve further, remember that and logic enables computers to make decisions based on the joint 88 00:07:21,430 --> 00:07:23,140 root of two inputs. 89 00:07:23,140 --> 00:07:29,950 So keep your curiosity kindled fellow adventurers as you venture deeper into the cooperative world of 90 00:07:29,950 --> 00:07:33,970 logic, the ever evolving realm of computers.
