12. 0:28Hello, my Class 12 champions. How are
13. 0:31you all? Welcome to today's exciting and
14. 0:33exciting session where we'll discuss the
15. 0:36top 50 most important IMP questions for
16. 0:38your half-yearly examinations.
17. 0:40That is, 50 important questions that are
18. 0:43very important for your half-yearly exam
19. 0:45.
20. 0:46So, friends, today we're going to do 50
21. 0:48questions, and I want to start right
22. 0:50away without any further delay.
23. 0:53My first question here is: What is a
24. 0:55database? What is a database? Explain
25. 0:58its purpose? I mean, what is a database
26. 1:00? I want to explain its purpose. It's a
27. 1:03very simple question. You'll have to do
28. 1:05it in your exam, and I know it comes up
29. 1:07. So, be sure to study it.
30. 1:10You'll definitely get two marks for it.
31. 1:13Question number two: What is data
32. 1:15redundancy? We know what redundancy
33. 1:17means.
34. 1:19What does redundancy mean? Repetition.
35. 1:22When something is repeated repeatedly,
36. 1:24it's called redundancy. So, kids, try
37. 1:27this question too.
38. 1:28Question number three: Write any two
39. 1:31advantages of SQL. Write any two
40. 1:33advantages of SQL.
41. 1:36We have to write two advantages of SQL,
42. 1:38this structured query language.
43. 1:40We have to write two advantages in the
44. 1:42exam. So, brother, what is this question
45. 1:44for me? It's important. So, be sure to
46. 1:46try this one too.
47. 1:47Let's move on to question number four:
48. 1:49What is a database management system?
49. 1:51Sir, we absolutely have to answer this
50. 1:53one. This question is quite simple: "
51. 1:56What is a database management system?"
52. 1:58We've seen it repeatedly in exams. So,
53. 1:59we absolutely have to answer this one.
54. 2:02Now, you'll ask, "Sir, who will answer
55. 2:03this?" I'll answer it, you kids. I'll
56. 2:06bring you all a live session where I'll
57. 2:08share all the answers.
58. 2:10Question number five: "When did SQL come
59. 2:12into existence?" When did SQL come into
60. 2:16existence? So, we have to answer this
61. 2:18one too. Because you get these questions
62. 2:20in both objective and subjective forms
63. 2:23in exams. So, be sure to study this one
64. 2:25. Question number six: "What is a file
65. 2:27system?" Absolutely have to answer it.
66. 2:29What is a file system? What is a file
67. 2:31system? Okay, we've studied database
68. 2:33management systems. What is a file
69. 2:35management system? We have to define
70. 2:36them separately. So, if I look at this,
71. 2:39it's a very important question for me,
72. 2:41worth two marks. Okay, brother? Let's
73. 2:43move on. Question number seven. What is
74. 2:46the Python library? What is the Python
75. 2:49library? Right? What is this Python
76. 2:51library called? Pay attention to this.
77. 2:54We also see this question in the exam
78. 2:56for two marks.
79. 2:57Okay, brother? Question number eight.
80. 2:59What is a series? Create an empty series
81. 3:02?
82. 3:03Now, sir, I understand what this series
83. 3:05is?
84. 3:06Right? What is this series?
85. 3:08But whenever I talk about creating an
86. 3:10empty series in Python, what is it?
87. 3:13So, don't worry about that either,
88. 3:15children. I will also explain what an
89. 3:17empty series is. How do you create an
90. 3:19empty series? It's very simple. I will
91. 3:21explain this to all of you very clearly
92. 3:23.
93. 3:23Question number nine: "What is data
94. 3:25visualization in Mat PlotLib?"
95. 3:28When we discuss the Mat PlotLib chapter
96. 3:30, these types of questions become very
97. 3:32important to me.
98. 3:34That is, what is data visualization
99. 3:36called in Mat PlotLib?
100. 3:38What is data visualization?
101. 3:40So, right? We have to pay attention to
102. 3:41this.
103. 3:43There are only a few questions in Mat
104. 3:43PlotLib: "What is Mat PlotLib?"
105. 3:45"What is data visualization?""What is
106. 3:46this plot?""What is this bargraph?""
107. 3:49What is this histogram?""So, you'll see
108. 3:50these types of questions."
109. 3:52So, you all have to pay special
110. 3:53attention to these questions as well.
111. 3:56Okay, kids?
112. 4:01Let's move on. Question number 10: "
113. 4:04What is Pillow Library?""What is this
114. 4:06Pillow Library?""So, what is this Pillow
115. 4:07Library?" So, you'll have to write about
116. 4:09this as well. This is also a two-mark
117. 4:11question. It's a very good question that
118. 4:12you'll see in the exam.
119. 4:14Question number 11: What are image
120. 4:16functions? Please explain, brother, what
121. 4:19are these image functions? I need to
122. 4:21explain them. So, let me explain it
123. 4:23briefly. What is it called? I am read,
124. 4:26you might remember.
125. 4:27The second is I am save, you might
126. 4:29remember that too.
127. 4:31The third is I am show, you might
128. 4:33remember that too. So, right? This is
129. 4:35how you will have to write the answer in
130. 4:36the exam. You will see it in three marks
131. 4:39and two marks.
132. 4:41So keep this in mind, and you have to
133. 4:43write this answer as well.
134. 4:45Okay, kids? So, do this too. Question
135. 4:47number 12: What is Jupyter Notebook?
136. 4:50What is this Jupyter Notebook? So, this
137. 4:52happens a lot in exams. We get stuck on
138. 4:54such questions in two marks. So, it is
139. 4:57important to read this. This is very
140. 4:59important. Okay, kids? Let's move on.
141. 5:02Question number 13: What is CP? What is
142. 5:05this CP? What is this CP? So, CP is also
143. 5:07a library that you'll have to write
144. 5:08about. So, this is important too.
145. 5:10Question number 14: What is the Pandas
146. 5:12library? What is the Pandas library?
147. 5:15It's a very simple question.
148. 5:17It's a very important question worth two
149. 5:19marks. So, do this. Okay? Question
150. 5:22number 15: What is Mat Plot Lib? Right,
151. 5:25its three features. Brother, what is Mat
152. 5:28Plot Lib? Tell me its three features.
153. 5:32Write down its three features. So,
154. 5:34brother, it's a very simple question.
155. 5:35What is Mat Plot Lib? We have to write
156. 5:37down its three features. So, we have to
157. 5:39answer this question as well.
158. 5:42Okay, kids? Let's move on. Question
159. 5:44number 16: What is network topology?
160. 5:47What is network topology?
161. 5:49Do it. This is a very important question
162. 5:52about network topology. Okay? Question
163. 5:54number 17: Right, three differences
164. 5:56between star and ring topology.
165. 5:58That means we have to write three
166. 6:00differences between star and ring
167. 6:02topologies.
168. 6:03We draw boxes for the differences
169. 6:05between them. We just need to draw that
170. 6:07box and write the difference between
171. 6:09them. So, this question must be written
172. 6:11this way. And I tell you that you'll
173. 6:13encounter questions about difference
174. 6:14between in exams. So, always write
175. 6:16properly by making boxes. You get proper
176. 6:18marking for it. IP is the only subject
177. 6:21in which you can score 100 out of 100 in
178. 6:24your main exams because writing in it is
179. 6:27quite simple. So, we have to keep that
180. 6:29in mind.
181. 6:30And if we always write in an exam
182. 6:32following a pattern, even if we write
183. 6:34small, meaningful answers, we will
184. 6:36definitely get marks for them.
185. 6:38So, write this answer following this
186. 6:40pattern. Question number 18: Explain
187. 6:42tree and mesh topology. What are you
188. 6:44talking about, brother? We have to
189. 6:45explain tree and mesh topology. Explain
190. 6:47both of these thoroughly in paragraph
191. 6:49form. This is also going to be a simple
192. 6:51question. So, this is also a special
193. 6:52question for me, worth three marks.
194. 6:55Okay? Let's move on. Question number 19.
195. 6:57What is a bridge? Explain its types?
196. 6:59Brother, what is a bridge? I have to
197. 7:01explain its types. So, this is also a
198. 7:03type of network device that you will all
199. 7:04study about. You will get a very good
200. 7:06answer to it today. Question number 20.
201. 7:08What is a data transmission mode?
202. 7:10Explain its types?
203. 7:12This question is very important. We have
204. 7:15three types of modes, which are called
205. 7:17simplex, half duplex, and full duplex.
206. 7:20So, we all have to keep this in mind;
207. 7:21you will come across this question in
208. 7:22the exam and you will have to write it.
209. 7:23Well, I will tell you one way to write
210. 7:24this answer. So you can write it this
211. 7:26way: If you always make a few flow
212. 7:28charts, your answers with these flow
213. 7:30charts increase your marks. Isn't it? So
214. 7:32, if you draw a flow chart in this way,
215. 7:34your marks increase because of all these
216. 7:36things, because the presentability of
217. 7:37the paper increases. So, in the IP paper
218. 7:39, just these diagrams and answers, all
219. 7:41these things, get more marks. So, we
220. 7:43have to do this question too. Question
221. 7:45number 21: What is an anaconda
222. 7:46distributor? What is an anaconda
223. 7:48distributor? Children, do it. In the
224. 7:50exam, you'll see such small definition
225. 7:53questions, and you get nervous. What is
226. 7:55this? I never read it. Where did this
227. 7:58come from? Oh, this didn't come from
228. 7:59anywhere. It's in this. It's part of the
229. 8:01book. You have to do it. So, memorize it
230. 8:03. Okay, brother? Let's move on. Question
231. 8:05number 22. What is a web browser? What
232. 8:07is a web browser? Right? What is a web
233. 8:10browser? And explain its three major
234. 8:12features. Explain its three major
235. 8:15features.
236. 8:16Right? I want to explain to you three of
237. 8:19its major features, which you use in
238. 8:21your daily life.
239. 8:23Be it Chrome, Firefox, or Internet
240. 8:25Explorer, anyone who has an iPhone uses
241. 8:28Safari.
242. 8:29What are all these? A web browser. Now I
243. 8:31want to tell you three of its features.
244. 8:33You use them, you can write them down.
245. 8:35Question number 23: What is a web page?
246. 8:38What is a web page? What is a web page?
247. 8:40So this is also a very simple question.
248. 8:42Solve it. It is worth two marks.
249. 8:45Question number 22: Explain the
250. 8:46difference between static and dynamic
251. 8:48web pages. Learn by doing it.
252. 8:50Learn by doing it.
253. 8:52This question is about explaining the
254. 8:54difference between static and dynamic
255. 8:56web pages.
256. 8:57I need to answer questions where I have
257. 9:00to explain the difference. And I have to
258. 9:02answer this question because it's
259. 9:04important. So, please do it. Okay,
260. 9:06brother. Question number 25: What is web
261. 9:08hosting? Why is it required? Brother,
262. 9:11what is web hosting? And why is it
263. 9:14needed? So, these questions are written
264. 9:17on the board. If someone is needed to
265. 9:19explain them, then what is it? Host?
266. 9:22Who is needed to make a website
267. 9:24accessible to people? So, what is it
268. 9:26called? Web hosting. I will thoroughly
269. 9:28discuss the answer in a live class,
270. 9:30where you will understand it clearly.
271. 9:31Question number 26: Explain the SQL date
272. 9:34function.
273. 9:35So, brother, we have date functions,
274. 9:37numeric functions, string functions, and
275. 9:39aggregate functions.
276. 9:42So, what is each one telling us? What
277. 9:43are these date functions supposed to do
278. 9:45? We need to explain them. He even gave
279. 9:46us the names. Create the NOW function,
280. 9:48the DATE function, the MONTH function,
281. 9:49and what are the YEAR functions supposed
282. 9:51to do?
283. 9:52Write them with example syntax. We'll do
284. 9:54it.
285. 9:55These syntax questions are often quite
286. 9:57easy to see in exams. You might get
287. 10:00nervous just hearing the word "syntax,"
288. 10:02wondering, "Sir, what is this syntax?
289. 10:04How do I do it?" It's nothing, my friend
290. 10:05. The first line has a short definition
291. 10:07.
292. 10:08The second line contains the syntax, and
293. 10:09the third line provides the output,
294. 10:11which you can do in a very simple way.
295. 10:13So, don't be afraid, brother. I'm here.
296. 10:15I'll explain everything in the simplest
297. 10:17way, which will help you on the exam.
298. 10:20So, you have to write SQL date functions
299. 10:21. These four are our functions.
300. 10:23We have to explain them and their syntax
301. 10:25along with examples.
302. 10:27So, those Hindi medium students who are
303. 10:29watching this video, don't worry. I'll
304. 10:31bring the answer in Hindi as well so you
305. 10:33won't have any problems with that either
306. 10:35. Okay, kids? Come on, sir. Let's move
307. 10:37on. Very good. Question number 27:
308. 10:39Explain the POW function, FLOOR function
309. 10:41, and SQRT function with syntax and
310. 10:43examples.
311. 10:44Right? Now, this is our second function
312. 10:46question. Right? These are called
313. 10:48numeric functions, for which POW stands
314. 10:50for power. Right? POW is short for power
315. 10:52. Look here, it's written the same in
316. 10:54Hindi: We have to explain the POW
317. 10:56function, FLOOR function, and SQRT
318. 10:57function with syntax and examples. So,
319. 11:00children, we have to prepare this very
320. 11:01well. You have to study this as well.
321. 11:04Now, let me tell you, many times,
322. 11:05questions like this are asked directly,
323. 11:07like, "Explain any five numeric
324. 11:08functions,""Explain any five aggregate
325. 11:10functions,""Explain any five string
326. 11:11functions."
327. 11:13Explain any five aggregate functions,
328. 11:15explain any four functions.
329. 11:17And many times, they're asked directly,
330. 11:19like, "This is the name of the function
331. 11:20.
332. 11:21Explain this one too." So, brother,
333. 11:23study thoroughly.
334. 11:24Even if you come across it this way,
335. 11:26you'll be able to explain it. And if
336. 11:27you're asked directly, you'll be like, "
337. 11:29Wow, brother, just write down whatever
338. 11:30comes to mind." So, there's nothing
339. 11:32difficult. Everything is simple. Okay?
340. 11:34Question number 28: Differentiate
341. 11:37between a DBMS and a file system. You
342. 11:39have to do this.
343. 11:41This question is very important. Okay?
344. 11:44What are you saying? Explain the
345. 11:45difference between a DBMS and a file
346. 11:47system.
347. 11:48You have to explain the difference
348. 11:50between the two. This question is very
349. 11:52special to me. This is very close to my
350. 11:54heart. I'll take care of it. This
351. 11:56question is very good. It's very close
352. 11:58to your heart. Sorry, by the way. I'm
353. 12:00your Kartik brother. Your IP educator.
354. 12:02So, remember all these things. Okay?
355. 12:04Let's move on to Question 29: Explain
356. 12:06the Advantages and Disadvantages of
357. 12:09Python. That is, we have to explain the
358. 12:12advantages and disadvantages of Python.
359. 12:15What are Python's strengths and
360. 12:18weaknesses? We have to write this down.
361. 12:20This is also a very simple question. Be
362. 12:21sure to do it. Question 30: Explain any
363. 12:24four applications of Python with
364. 12:26examples.
365. 12:28That is, we have to explain any four
366. 12:30applications of Python with examples.
367. 12:33Now, brother, what does "application"
368. 12:35mean? So, application means what can I
369. 12:37do with Python? I can create
370. 12:39applications with Python. I can create
371. 12:41websites. I can create games. I can do
372. 12:44scripting. This is called scripting
373. 12:45language. So I'm able to do all these
374. 12:47things. So what do you call all these
375. 12:49things? Children call it application,
376. 12:50and what would you call it in English?
377. 12:52Application. So, this was a fairly
378. 12:54simple question. You have to answer it.
379. 12:56It's important, and if we do it with
380. 12:58examples, we'll get a very good answer.
381. 13:01Okay, dear children, did you all
382. 13:03understand this?
383. 13:10Let's move on. Now let's talk about
384. 13:13question number 31. What does question
385. 13:15number 31 say?
386. 13:17Write differences between series and
387. 13:19data frames. Brother, write the
388. 13:20difference between series and data
389. 13:21frames. This is a differentiating
390. 13:22question. You have to write the
391. 13:23difference between the two. This is a
392. 13:25variant question. We have to do it.
393. 13:27Question number 32: What are computer
394. 13:29network devices? Explain their types.
395. 13:31What are these computer network devices
396. 13:33? What are computer network devices? I
397. 13:35have to explain their types. What are
398. 13:38the types? Router, bridge: It's called a
399. 13:41router, not a router. Right? Pay
400. 13:43attention. We get confused between
401. 13:44router and router. Kids say router.
402. 13:47Router, bridge, hub, right? There are
403. 13:49different switches, different network
404. 13:51devices, so you have to write their
405. 13:52names. They're called the same types.
406. 13:54This is a simple question. Question
407. 13:55number 33: Write four differences
408. 13:58between router and switch. Look, read it
409. 14:00in Hindi. What is written here? Router.
410. 14:03And you have to write four differences
411. 14:04between switch. So, write four small
412. 14:06differences. Your work is sorted, your
413. 14:08life is sorted, my life is sorted.
414. 14:09That's it. Okay? It's a very simple
415. 14:11question. Come on, sir. Let's move on.
416. 14:12Question number 34: Write four
417. 14:14differences between ring and bus
418. 14:16topology.
419. 14:17Brother, I have to explain four
420. 14:19differences between ring and bus
421. 14:21topology.
422. 14:23I have to write four differences. That
423. 14:25means, write four differences between
424. 14:27ring and bus topology. Are you getting
425. 14:29it? It's a very simple question. You
426. 14:30have to solve this one too.
427. 14:32Question number 35: What is a website?
428. 14:35What is a website? And explain its types
429. 14:38? You have to tell us about that too.
430. 14:41What is a website? Explain its types.
431. 14:44It's simple. You have to do it. Question
432. 14:47number 36: Explain land and water with
433. 14:49examples. Brother, do this.
434. 14:52This is an important question: explain
435. 14:55local area network, metropolitan area
436. 14:57network, and wide area network with
437. 14:59examples.
438. 15:00So explain it very well. The answer is
439. 15:03excellent.
440. 15:04You will get excellent marks for this.
441. 15:06Very good. Let's move on. Question
442. 15:08number 37: Explain head function. Okay,
443. 15:10let me tell you what this is called? We
444. 15:12call it function. So many students might
445. 15:14be thinking, "Sir, function isn't
446. 15:15written anywhere. Why are you saying it
447. 15:17?"
448. 15:17So, when we code in IP, these little
449. 15:19brackets are called functions.
450. 15:22They're called functions. Okay, kids? We
451. 15:24need to explain the head function and
452. 15:26tail function methods with examples.
453. 15:28What are you talking about? We need to
454. 15:29explain the head and tail methods with
455. 15:31examples. So, these two functions, head
456. 15:33and tail, are very important.
457. 15:35We'll understand them very well.
458. 15:37I'll answer them in abbreviated
459. 15:38programming terms, which you'll
460. 15:40understand very easily.
461. 15:43Okay? Let's move on to question number
462. 15:4538: What is CSV data? What is CSV data?
463. 15:48Right? What is CSV data? And explain its
464. 15:51features and uses? Explain its features
465. 15:55and uses. CSV is a comma-separated value
466. 15:58.
467. 15:59What is it? You need to write about it
468. 16:01and some of its features and where it's
469. 16:04used.
470. 16:05You need to write about that. Very
471. 16:07simple answer, sir. It's a simple
472. 16:08question that we have to answer.
473. 16:10Question number 39: What is a web server
474. 16:13? What is a web server, brother? What is
475. 16:15a server? Where all the details are
476. 16:17stored. All the data is stored. It is
477. 16:18taken from there and made available to
478. 16:19people. So, what is the web after that?
479. 16:22So, think about it a little and answer
480. 16:24it. It's a very nice, simple question.
481. 16:25Let's move on.
482. 16:27Question number 40: Explain the function
483. 16:29of the CREATE TABLE and ALTER TABLE
484. 16:31commands in SQL with syntax.
485. 16:33What is he saying?
486. 16:35We have to explain the function of the
487. 16:37CREATE TABLE and ALTER TABLE commands in
488. 16:39SQL, along with their syntax.
489. 16:41That is, we have to explain these two
490. 16:43commands that have been given to us.
491. 16:44They are very simple. We will understand
492. 16:46them thoroughly. This is important. It
493. 16:48is necessary to do this. So, there is no
494. 16:49need to worry, friends. Okay? Question
495. 16:51number 41: Explain the group by. This
496. 16:53question is important, I'm going to
497. 16:54answer it right now.
498. 16:57The group by clause, the order by clause
499. 16:59, and the having by clause—you'll see
500. 17:00one or two of these in the exam, and
501. 17:02they're worth three or four marks.
502. 17:05So, this becomes very important for us.
503. 17:08What is he talking about, brother?
504. 17:09We have to explain the SQL group by
505. 17:11clause, order by clause, and having by
506. 17:13clause with syntax and examples.
507. 17:15So, we'll create a small program, give
508. 17:17an example, and write the answer in a
509. 17:19very good way.
510. 17:21We'll present it perfectly. You'll get
511. 17:24full marks in the exam. Okay? So, do
512. 17:26this question. I made a very poor star
513. 17:29here. So, I'll make it better.
514. 17:31Ringer ringer, every day, it's full of
515. 17:33phosies. Okay? So, here's the star. So,
516. 17:35be sure to make this one. Don't make
517. 17:36stars. Be sure to complete the questions
518. 17:38. Okay, Question 42: Explain histogram
519. 17:40plots and line plots with examples.
520. 17:44Brother, I have to explain the histogram
521. 17:45plot and line plot with examples. So,
522. 17:47this is part of the types of plots. Do
523. 17:48this as well. This is also important.
524. 17:50Question 43: Explain the function of
525. 17:53rename table. Look, now another one has
526. 17:55appeared.
527. 17:55And drop table, this is another command
528. 17:58in SQL.
529. 17:59Right? What are you saying, brother? We
530. 18:00have to explain the function of the
531. 18:01rename table and drop table commands in
532. 18:02SQL.
533. 18:06Just like the alter and create table
534. 18:06commands that appeared earlier, you have
535. 18:07to do the same with this one.
536. 18:09It's not difficult.
537. 18:10Don't worry, brother. I'll explain
538. 18:11everything. We'll do everything easily.
539. 18:13Okay, brother? Well done. Question 44:
540. 18:15What is a network hub?
541. 18:16What is a network hub?
542. 18:18What is a network hub? What is a network
543. 18:20hub? Explain its types. I have to
544. 18:22explain its types. What is a network hub
545. 18:24? And there are some types of it, I have
546. 18:25to tell you about them. So you will get
547. 18:27the answers to these in the live class.
548. 18:28Don't worry, boss. Until you find these
549. 18:30answers, read the questions and activate
550. 18:32your brain before Diwali. Okay? Question
551. 18:34number 45, what is URL? Write a short
552. 18:36note. What is this URL? What is Uniform
553. 18:39Resource Locator? Its full form can be
554. 18:41written in one word, and this answer can
555. 18:42also be written in two marks.
556. 18:44There is a short note on it. Right?
557. 18:47Shorten it and write it down, brother.
558. 18:49You must write it. Right? So, children,
559. 18:51do this too. This is also important for
560. 18:52me. Question number 46. What are the
561. 18:55advantages and disadvantages of DBMS? I
562. 18:57have to write the advantages and
563. 18:59disadvantages of DBMS.
564. 19:01Simple. So, we also have to answer this
565. 19:04question: what are the advantages and
566. 19:06disadvantages of databases? I'll have to
567. 19:08explain it. So, kids, please do this
568. 19:10question too.
569. 19:12Question number 47: Explain the
570. 19:13concatenate function, the four-length
571. 19:15function, and the insert string function
572. 19:18with examples. Look, what has he done
573. 19:20here? One, two, and three. So, what
574. 19:24happens often is that someone directly
575. 19:26sees the names and asks you, "Explain
576. 19:28the concatenate function, the four-line
577. 19:30function, or the insert function."
578. 19:32And many times, they'll say, "Explain
579. 19:34any four string function."
580. 19:36So, your brain doesn't work. What are
581. 19:37these string functions, what is this
582. 19:39aggregate? And when he gives the names,
583. 19:41do you understand? Hey, was he talking
584. 19:42about this? This is what you need to do
585. 19:44so you won't get confused. These are
586. 19:46divided.
587. 19:46If you divide them in the same way and
588. 19:48remember them, your work will be easier
589. 19:49. So, we have to explain the concatenate
590. 19:51four-length function and the
591. 19:52insert-string function with examples. So
592. 19:54, kids, we'll have to do this question
593. 19:55too.
594. 19:56Now, look below, there's a very
595. 19:58well-written question: Explain any five
596. 20:00aggregate functions in SQL. I mean, I
597. 20:02have to explain any five aggregate
598. 20:04functions in SQL.
599. 20:05To explain these five functions, a
600. 20:07direct question like this can come up in
601. 20:09the exam. Many times, they'll ask, "
602. 20:10Brother, explain these five aggregate
603. 20:11functions," and many times, they'll even
604. 20:13give names and say, "These four names
605. 20:14are written. Please explain them."
606. 20:16So, both of these questions are
607. 20:17important. They can come in both
608. 20:18variations. So, you definitely have to
609. 20:20do it. Okay? Let's move on to my last
610. 20:23important question: What is the Internet
611. 20:25? Right? What is the Internet? You all
612. 20:28use it, so you all know the answer to it
613. 20:31. So, definitely do it and write any
614. 20:33three uses of the Internet. Write any
615. 20:35three uses of the Internet. What are you
616. 20:37saying? Write three uses that you know.
617. 20:40So brother, this is very simple. You use
618. 20:41the internet. Do you know what its uses
619. 20:43are? What are its uses? So this is a
620. 20:45simple question and it comes in two or
621. 20:47three marks in the exam. So do solve
622. 20:49this.
623. 20:50Question number 50 last question. What
624. 20:52is computer network architecture,
625. 20:54explain its types? Children, there are
626. 20:56two types of computer network
627. 20:58architecture. One is peer to peer
628. 21:00architecture and the other is client
629. 21:01server architecture. So you have to
630. 21:03solve these also in the exam. These are
631. 21:05also asked in a different way, brother,
632. 21:08what is P2P? That is, what is peer to
633. 21:09peer architecture? And the second
634. 21:11question is what is client server
635. 21:12architecture? So you can also see
636. 21:14questions in this way in the exam. So
637. 21:17you have to keep in mind that the
638. 21:19student may also ask about computer
639. 21:20network architecture and may also ask to
640. 21:23tell about its types or many times he
641. 21:24may ask what is this P2P called and what
642. 21:26is this client server architecture
643. 21:28called.
644. 21:29Is it okay kids? I hope you must have
645. 21:31understood all these important questions
646. 21:33very well.
647. 21:35These were very simple questions. You
648. 21:36must have understood them very well. So
649. 21:38thank you so much for joining this
650. 21:40session. See you in the next class. Till
651. 21:42then, bye bye, take care, peace out,
