1 00:00:00,840 --> 00:00:01,990 Hello and welcome back. 2 00:00:02,430 --> 00:00:09,540 In this video, we are going to do a practical walkthrough on their behavior and look how the expert 3 00:00:09,540 --> 00:00:15,870 directory structure, which the country to the air and comparing the V90 large. 4 00:00:17,630 --> 00:00:20,660 So I mean, maybe two machine windows seven. 5 00:00:22,080 --> 00:00:23,650 I created a photo call. 6 00:00:23,670 --> 00:00:24,600 Now they have to. 7 00:00:26,040 --> 00:00:34,470 And then you can go in download this zip file this project and Zip, put it in my desk to inside here 8 00:00:34,500 --> 00:00:44,190 I have a window and the Dark Age here for which you can obtain by reading this, opening this text file 9 00:00:44,190 --> 00:00:45,790 here you show you writing it. 10 00:00:46,530 --> 00:00:50,220 He might be slightly different for yours, but basically he's in this. 11 00:00:51,210 --> 00:00:54,990 So to get this view 90, you will go to this path here. 12 00:00:55,230 --> 00:01:04,730 It means you open the sea dry, cleaning your seafood and go to program for x86 and then go to windows. 13 00:01:04,830 --> 00:01:05,090 It's. 14 00:01:07,310 --> 00:01:12,720 Can they look for 10 for Windows, 10 in before eating food? 15 00:01:13,790 --> 00:01:15,590 And they look for 10 zero zero? 16 00:01:15,950 --> 00:01:18,470 Maybe this number here helping is. 17 00:01:19,720 --> 00:01:25,390 And then you say here there's a U.N. for the one year for Libya and throughout the region. 18 00:01:26,820 --> 00:01:31,620 And then w-, you should be able to locate your win in the. 19 00:01:34,250 --> 00:01:44,790 He's the one who invented a hedge, so a copy of me and he he copies in and put in this for the two 20 00:01:45,080 --> 00:01:45,740 I this one. 21 00:01:48,940 --> 00:01:49,420 Copy and. 22 00:01:50,470 --> 00:01:56,350 So the reason the copyright is you don't want to accidentally add is far from this location. 23 00:01:57,850 --> 00:02:02,830 So now you can open this, we need a huge rectly added, you know that? 24 00:02:05,130 --> 00:02:13,960 And while you know, that is open, you can control if you search or you can just click on this search, 25 00:02:13,960 --> 00:02:19,680 you search, find and here look for a spot. 26 00:02:19,830 --> 00:02:21,120 And it's called dear. 27 00:02:23,820 --> 00:02:25,200 You finally just go on. 28 00:02:26,130 --> 00:02:31,710 So this is a structure for the part of the paper that contains the export directory. 29 00:02:32,790 --> 00:02:41,870 Now we are going to open the country to the L in B using B B. 30 00:02:42,540 --> 00:02:44,660 So let's go and look for an entity to the. 31 00:02:46,250 --> 00:02:54,650 Connected to the oil is found in the sea dry windows system, 32. 32 00:02:57,040 --> 00:02:58,290 System System32, 33 00:03:01,380 --> 00:03:03,120 again, you can scroll down. 34 00:03:04,860 --> 00:03:07,890 And under care, there should be kind of three to. 35 00:03:09,430 --> 00:03:09,790 Yeah. 36 00:03:09,820 --> 00:03:11,790 So you can directly copy this. 37 00:03:13,150 --> 00:03:18,860 A PC in your this folder here, 90s. 38 00:03:20,830 --> 00:03:24,160 All right, so this way you accidentally go in this far. 39 00:03:24,910 --> 00:03:26,710 So now you can open this web. 40 00:03:27,190 --> 00:03:28,930 So fire your bidet. 41 00:03:32,420 --> 00:03:40,040 Now, all of these these files here shortcuts, so these shortcuts created from the flight order and 42 00:03:40,040 --> 00:03:41,000 the activities. 43 00:03:42,790 --> 00:03:45,400 You can find your B that he actually. 44 00:03:46,610 --> 00:03:52,370 He would be back, you just right click and drag to the desktop to create your shortcut. 45 00:03:56,380 --> 00:03:57,670 So now open feedback. 46 00:03:59,550 --> 00:04:02,950 And then you're going to jail in the. 47 00:04:06,690 --> 00:04:08,160 And BBC Sun say. 48 00:04:10,350 --> 00:04:13,350 So if you go to the option here, there. 49 00:04:15,020 --> 00:04:21,520 It is, but highly paid it, scroll down, you can see, and that has punditry directory structure, 50 00:04:21,520 --> 00:04:22,510 he said this address. 51 00:04:23,620 --> 00:04:26,740 So this is Schoharie reality to address. 52 00:04:27,610 --> 00:04:32,600 So if you want to follow this in the memory, you just right click is full. 53 00:04:32,860 --> 00:04:34,360 Are we in the FC? 54 00:04:34,780 --> 00:04:36,340 Click on it and you come here. 55 00:04:36,970 --> 00:04:37,960 Yes, how you get this? 56 00:04:39,010 --> 00:04:43,120 So now this is a off your spot that it is right here. 57 00:04:43,750 --> 00:04:50,200 And this is the member of the structure, so you can see characteristics here. 58 00:04:50,470 --> 00:04:52,750 Refer to give it. 59 00:04:54,050 --> 00:04:57,020 Which is this four characters this form right here? 60 00:04:58,500 --> 00:05:07,360 Album Money Song Zeros, and then if you want to have a human readable view of this, all you need to 61 00:05:07,360 --> 00:05:09,220 do is click on next step. 62 00:05:10,910 --> 00:05:15,110 And then you can see the human readable view for all these bites here. 63 00:05:16,140 --> 00:05:24,410 So characteristics here is referring to this four year because it's a dual format and the value is always 64 00:05:24,420 --> 00:05:33,770 zero zero next only stand is in the Valley five five four six three one five, which is this in reverse 65 00:05:33,790 --> 00:05:37,580 Phi Phi for the S.S. when fight. 66 00:05:40,000 --> 00:05:49,510 Next, one major motion, two zeros to advice, you can confirm here you can see pediatrician and then 67 00:05:49,540 --> 00:05:55,240 here my new addition is an excellent also zero referring to two base here. 68 00:05:56,170 --> 00:06:00,490 And the next one will be a name, a 364 here in. 69 00:06:01,060 --> 00:06:10,390 So this name is a name for this year, and the name is following this address a 364, which is this 70 00:06:11,020 --> 00:06:13,060 a three six four? 71 00:06:14,270 --> 00:06:20,900 So you can actually click this and follow this here and now you will see. 72 00:06:21,850 --> 00:06:30,510 And this address is a name, Colonel 9:57 referring to this connected, you can tell that via Zoom enough 73 00:06:31,630 --> 00:06:34,360 now to go back to the previous RV. 74 00:06:34,720 --> 00:06:37,990 Just click on that you go back to the. 75 00:06:39,550 --> 00:06:44,980 Now the next one is this one, so a busy highway is one. 76 00:06:45,160 --> 00:06:47,140 So this refers to this one. 77 00:06:47,140 --> 00:06:50,130 Here is for back to me. 78 00:06:51,130 --> 00:06:59,710 So this one here is telling you that the ordinal starts from one deciding a Saturn one. 79 00:06:59,710 --> 00:07:01,360 So we have a few ordinance. 80 00:07:02,440 --> 00:07:10,420 You have to remember to get to the base one to get the actual arena. 81 00:07:11,110 --> 00:07:12,400 So that's the meaning of this. 82 00:07:12,880 --> 00:07:15,490 These are offsets and this is the base. 83 00:07:15,850 --> 00:07:22,550 So if you if you want to calculate the actual know, you need to take these numbers at the base and 84 00:07:22,570 --> 00:07:23,950 then you get your chance in a. 85 00:07:26,920 --> 00:07:30,880 So there's a meeting on this next one is number of functions. 86 00:07:31,720 --> 00:07:33,190 Assign them no functions as a diva. 87 00:07:33,730 --> 00:07:37,510 So here the normal functions is Hex five seven. 88 00:07:37,510 --> 00:07:45,700 Oh, which in this case vice handle and the number of names also see x y. 89 00:07:45,730 --> 00:07:52,120 So that means that five hundred and seventy functions in Hex. 90 00:07:53,200 --> 00:07:59,000 So you want to know actually how many of these you have to convert into decimal. 91 00:07:59,020 --> 00:08:03,580 You can use their calculator, you can convert Hex. 92 00:08:06,020 --> 00:08:10,670 So they're facing zero in decimal. 93 00:08:10,850 --> 00:08:14,390 It is one thousand three hundred two functions. 94 00:08:14,900 --> 00:08:18,740 So currently through the has gone one thousand three hundred ninety two functions. 95 00:08:19,040 --> 00:08:20,240 Hey, spot that tightens. 96 00:08:21,950 --> 00:08:24,440 So these two are referring to the fi sound. 97 00:08:24,440 --> 00:08:24,980 Really nice. 98 00:08:25,760 --> 00:08:26,570 No function. 99 00:08:26,570 --> 00:08:27,500 Refer to this. 100 00:08:29,120 --> 00:08:30,930 A number of. 101 00:08:32,600 --> 00:08:35,540 Names refer to this is one. 102 00:08:36,930 --> 00:08:44,010 So a number of functions referring to a number of her address here, actually, and my needs us to refer 103 00:08:44,020 --> 00:08:44,460 to this. 104 00:08:45,630 --> 00:08:47,870 So he got that done. 105 00:08:48,010 --> 00:08:50,790 Her next one is to address all functions. 106 00:08:51,450 --> 00:08:59,850 So this is the address where you have an array containing all the functions so you can right click this 107 00:09:00,150 --> 00:09:01,290 folder, Harvey. 108 00:09:01,770 --> 00:09:02,820 And here you go. 109 00:09:03,900 --> 00:09:05,310 So the first address is. 110 00:09:06,730 --> 00:09:09,610 This one, the first function, he said, is address. 111 00:09:11,190 --> 00:09:19,920 He he wants zero, and you can even see here he he won't see zero second function, he said his address. 112 00:09:22,130 --> 00:09:28,870 He even even he he when he when he is here, it is functioning, so this address. 113 00:09:32,920 --> 00:09:35,170 Three zero three three zero. 114 00:09:35,320 --> 00:09:37,630 And you can trace it all the way down. 115 00:09:38,080 --> 00:09:43,990 So this is the original memory which contains the real functions. 116 00:09:44,410 --> 00:09:53,200 So this area of function here is also known as a spot address table, which we have seen before in the 117 00:09:53,200 --> 00:09:54,070 PowerPoint tonight. 118 00:09:54,910 --> 00:09:57,220 This is a spot address table. 119 00:10:02,680 --> 00:10:05,200 And then in the next one is the address of names. 120 00:10:05,890 --> 00:10:09,670 So this is a friendly name for each of these functions. 121 00:10:10,540 --> 00:10:17,350 Here you only see addresses of the aforementioned you don't know what they are, but this this table 122 00:10:17,350 --> 00:10:19,900 here, this array here tells you what they are. 123 00:10:20,350 --> 00:10:23,740 So you can actually click on this now and follow the memory. 124 00:10:24,840 --> 00:10:30,960 So the first first address, which is this one, a few nights. 125 00:10:32,100 --> 00:10:39,330 A three nine, six nine one contestant name the first function correctly likeliness and follow this 126 00:10:40,290 --> 00:10:46,720 and then in memory, you can see the name of the function, which is acquired exclusive and you gave 127 00:10:46,760 --> 00:10:48,920 and you will see acquire licensee. 128 00:10:50,810 --> 00:10:56,030 You can do the same thing for the next one, right click for this information, and you can see the 129 00:10:56,030 --> 00:10:57,250 second one is so long. 130 00:10:57,470 --> 00:10:58,490 Is quite exclusive. 131 00:10:58,880 --> 00:11:03,770 Now you can take a look at this, right click this and go there. 132 00:11:03,770 --> 00:11:07,790 You can see is had had them, he added to me and so on. 133 00:11:08,780 --> 00:11:14,150 So this is a real friendliness, which is human readable strings. 134 00:11:15,020 --> 00:11:18,710 All right, the next one ordinance rectly follow. 135 00:11:19,550 --> 00:11:21,280 And this is very ordinance type. 136 00:11:21,990 --> 00:11:31,010 So ordinance signed to Vice what which is to base the first ordinance zero zero and this one uses zero 137 00:11:31,010 --> 00:11:34,940 one eight one two zero two and zero three and so on. 138 00:11:35,180 --> 00:11:37,100 And they're referring to this column here. 139 00:11:38,870 --> 00:11:47,180 So as you recall from our site, the ordinance is the numbers referring to the location in the address 140 00:11:47,570 --> 00:11:54,230 where they are met, where each of these function needs are met in the address that there is a purpose 141 00:11:54,230 --> 00:11:55,130 of ordinance. 142 00:11:56,360 --> 00:12:00,640 OK, so there's a meeting about this spot, actually. 143 00:12:01,850 --> 00:12:07,910 The only thing you need to be aware of is that some of these effort going forward is now this amazing. 144 00:12:07,910 --> 00:12:16,310 And see for this mean that this addresses contained does not contain the actual code for that function, 145 00:12:16,910 --> 00:12:21,650 but you need to refer to another year for that actual code. 146 00:12:22,430 --> 00:12:26,980 So how do you know that this is not the IP address of your chocolate? 147 00:12:27,800 --> 00:12:37,460 You have to compare the if range how they explained that a tree so your x y data nine FC plus CFC when 148 00:12:37,460 --> 00:12:40,340 we give you the range on the spot territory. 149 00:12:40,910 --> 00:12:51,920 So if you are, if this particular address is false within within this range, then you can be sure 150 00:12:51,920 --> 00:12:52,970 that it is. 151 00:12:55,410 --> 00:13:05,970 It is a forwarding address, so be hit below that we need to go and look up and try to find the functioning 152 00:13:06,150 --> 00:13:09,030 condition for this function. 153 00:13:10,270 --> 00:13:14,650 Some of we don't have this folding, for example, like edit them. 154 00:13:15,010 --> 00:13:22,090 So for those instances you can use and likely follow this, and in here you can see the actual implementation 155 00:13:22,390 --> 00:13:26,300 for that particular function for the rest. 156 00:13:26,350 --> 00:13:29,470 You will need to follow the folder. 157 00:13:30,430 --> 00:13:39,430 So this is basically the practical walkthrough on examining the --, specifically the export 158 00:13:39,460 --> 00:13:40,120 territory. 159 00:13:40,720 --> 00:13:47,980 So these are basic knowledge which you need to have for these costs and to be using this basic foundational 160 00:13:47,980 --> 00:13:50,590 knowledge in the coming lessons. 161 00:13:50,950 --> 00:13:52,900 So that's all for these practical. 162 00:13:53,350 --> 00:13:55,480 Thank you for which he.
