Assalamu Alaikum, how are you? Can you hear me? Walaikum. Assalamu Alaikum, sir. I can hear you. I am fine. Alhamdulillah. Today, in your foundation class lecture one, we will learn about the evolution of ICT. The things that I will write down should be written down. Okay? Please tell me who is watching from which course.

Sir, we are from the foundation course. What foundation have you enrolled in? BCS Bank all together, sir. Everything together. That's what was said. Yes, everything together. All of the foundations together. Okay, sir, I haven't had a class with you before, but we had a few conversations. Today is my first class. So, yes,

sir, I teach ICT, so this is my first meeting with you about ICT. We will have an overall discussion about ICT. We will

write down the topics that are important to us for any exam in Bangladesh, from BCS to bank exams. Okay? This means that you can cover the topic 100 percent if you study these ICT topics. For example, the history of computers, history and generations. History and generations of computers. There

are many topics related to computer hardware, software, software,

another software called firmware, you need to know about number systems and digital electronics, digital electronics, and the last one is networking, networking and data communication, hacking, hacking tools, etc. You will find them all, write them down. Yes. You will not find any sheets or lecture sheets for this. This is why you need to write it down.

Peace be upon you. Yes. Peace be upon you. Sir. Do you know the number three? Software is number three, sorry software plus farm war thank you sir, I have never met anyone before, right, sir, it was not today, okay, okay,

since you have been admitted to the foundation for all the courses, is there a target target that if there is a job like this, I will do it, if not, I will not do it, sir, is there a

target, madam, you said

BCS, sir, BCS, sir, in BCS, these topics, that is, from my course, from my classes, there were approximately 13 common topics, only in ICT, there were 14 in science, total 27 common topics,

and it would have been better if you took our science class, the person takes it and what do you do, this is what is happening, yes, you, I will take your ICT, let's see what happens, this is what is happening, we will see later whether there is any. There is another sir, he

takes the science section. I don't always buy everything. Sometimes I take whatever I want from Vidyabari in two batches. So let's start with ICT. So everything is written? It's over. The end. Everyone's writing? Yes, sir. So here are six, sorry, five topics, how many classes do you have on your course? Seven, seven, seven, six. I

don't know how many classes you have. Sir, it hasn't been given. I think you know how many classes there will be in the course, so I said, yes, there will be six classes. How many? There will be six classes. There will be another test in the middle. So these are six classes. Five topics for six classes. Six classes.

You will have six classes. It is becoming number one today. Then forward. And you will get five classes. So we're heading to the history of computers. History. The history of computers [clears throat] begins with the abacus. From where? Abacus. It is called the first computer. So which is the first computer? The first computer was the

abacus. This abacus could add, subtract, multiply, and divide 3000 years ago. And it was discovered in Babylon. So about 43,000 years after the abacus, we get the mechanical calculator. And this calculator is the successor to the modern calculator. And for this reason, Liveness is called the father of the calculator, the successor to the modern calculator.

So who was the inventor or father of the calculator? The father or inventor of the calculator. Who was the inventor?

Who will I tell?

Can you hear this? Yes, sir. We have to talk. Yes. Then it's okay. We got the calculator from Abacus. Many years later, two more devices were created , the computer. One is the difference engine. Difference engine. This happened in 1822. Another is the analytical engine. Analytical engine. The Analytical Engine was created in 1833.

So we all know the name of the person who built these two engines. Charles Babes. The name is Charles. Do n't you know him? Sir. He was a mathematician by profession. Who was it? Mathematician by profession. He was a mathematician. So when was the Analytical Engine created? In 1833. Which is the first computer?

Abacus Computer Abacus is the

last written so far. Yes, sir. So if you have a business, why do n't you hire people? Do n't do it all alone, people will work together. The person who was appointed to this analytical engine is called Lady Ada. Lady Ada Augusta. So who was called Lady Ada Augusta? So what do we call the

programmer or user of the analytical engine? So who was the programmer of the analytical engine ? Eder, then we write some of the titles of this Eder. Edo was also a mathematician by profession. Lord Byron's daughter. He was a friend of Charles Babbage. Lord Byron was a friend of Charles Babbage. And my friend's daughter, Ada, is a mathematician.

And this analytical engine programmer, and because of that, she was given the title "Mother of Programmers." 100 years after her death, she was given another title, "First Programmer in the World." Who was the first programmer in the world? Ready Ada Augusta Lovelace. Later, an Ada programming language was written in his name. So

what is the name of this one? Programming. Name of the programming language. Language name. Okay. And what generation's language is this? It may come up in the exam. Then you would say 3G or high level language. You

won't get any lecture sheets if you take the entire 3G or High Levels. And I hope that whatever you write will be directly common from here in any exam. Do

n't take a screenshot again. You have another habit. What to take? Do you have a habit of taking screenshots? Do

n't take a screenshot. Your screenshot will remain a screenshot. Even if the exam is over, you wo n't remember it.

Last thing you wrote was Sir, who was the father of the calculator? What is the

name of this demon? Sir, the name of programming. Programming language. Programming language, which generation of language is it, sir? High Level Language or 36 Which was the first computer? Abacus. So, what I have read so far will remain in my mind? InshaAllah. InshaAllah.

Now, what were these two engines of Charles Babbage? Difference Engine and Analytical Engine Difference and Analytical Let's take a look at the main parts of the Analytical Difference and Analytical Engine. The main part of this engine was one, which was the input, process, and output. How many parts were there? Three. And the current computer is built on these three parts.

So tell me, on whose architecture is the current computer based?

Charlesbase. So, is the current computer based on the design that Charles Babbage created, and for that reason should he be given a title or the Father of Computer? So who exactly was the father of computers? For what contribution is he called the father of computers?

Not for the invention of the difference engine, but for the fact that the difference and analytical engines had three parts, these two and three parts. So how many parts are original in the current computer ? Three. Three. So whose design are you building on ? Salsbase. And what would you say to him for this reason?

Father of Computer. Father of Computer. Computer.

Finished writing, ok very good, now come with this engine, since when this Charles Babbage got the title of Father of Computer, but he was a dead man, yes, then a dead man became a father, will the neighbors take it for granted, other scientists will accept it, won't the neighbors like it after seeing your success,

sir, they won't want to get that job either, yes sir, similarly, a "yeah" starts among the scientific community that we too will become fathers. They started researching this to break it. So many scientists give up after many years of research here. Just a scientist, he spent 10 years researching analytical and difference engines.

And after 10 years of research, they found a problem. The problem is that after you give input, the processing is finished and the output is given. If you need to see the results or output again, what do you have to do from the beginning? Input is required. Process output. Does that mean you will

pay more every time you see the output? Please provide input. Which makes it boring, doesn't it? Yes, sir. To get rid of this boring process, we found a solution that since we are losing the output, we can keep this output in the storage. Where can we keep it? We can keep it in the storage. The storage unit is

added here. Now you will keep the result in the storage. When you need to see it, you will see it from the storage again. If you do not need to give input again, this storage is added here. After how many years, 10 years, 10 years of research, and then this person's name is John von Neumann. John von Neumann.

So John Neumann. John von Neumann. How many years did he research and solve the problem here? But the main part or foundation is not being changed. Sir, even if he cannot, he is working. Sir. And because of this work, he should be given some title, should he not, should he not, should he not,

that is why he is given the title of Father of Modern Computers. Now, do you notice that we are now in the era in which computers have memory cards or not? Yes. Don't have a memory card in your mobile or computer? Yes, sir. Yes.

So whose foundation are we on now? John Newman is

called the father of modern computers for this reason. Actually, do you ever read it like this? Do you not read it with the contributions? Do you just memorize it? The father of computers, the father of

modern computers, just memorize it like this. That's why you don't remember it anymore, so you have to clear your throat again in the exam hall. Okay, sir, the writing is over. Very good. Now let's move on to these three parts. A technical evolution of them has been created in the current computers. So let's try to understand the evolutions a little.

So we moved into the computer generation. Yes, computer generation. So there are a total of five computer generations or evolutions. How many? Five o'clock. When we first started building computers, we followed this difference engine. After the Difference and Analytical Engine, the name of that engine is Mark One. Mark One, look, let me

show you a little bit. Let me show you whether there is a net on the board or not. Then you will understand what is coming from our computer today.

Hmm, the story of the world. Well, I couldn't show you. I will show you later what else is coming. It's not coming.

Yes, the keyboard is not really there, so writing is a problem. So after the analytical engine, we started generation. So when did the generation start? After the analytical engine. Can you hear me? Yes, sir. Well then we start with the first generation. The first generation of computers were made with vacuum tubes. With what?

[Coughing][Clearing throat] Vacuum tube. Vacuum tube or airless is good, airless is good, vacuum tube or airless is good, clear, so I can explain that due to the installation of this bulb, the weight of the computer becomes very heavy, from 10 to 50 tons. How many tons is 10? 50 tons. 50 tons. So what if the first generation

computer weighed 27 and a half tons? True or false? True. And here the computer language was machine language. So the name of the language of this generation of computers is machine language, machine language or object code or object language or zero or one. What does zero one mean? Binary is a binary language. So what is the basic language of the machine?

Which language can be directly understood by the machine? What is the

basic language of the machine? Which language can be directly understood by the machine? Brother, binary, sir. Binary language. Can machines directly understand languages other than binary? No, sir. If I didn't speak Bengali, I would speak Chinese. Do you understand? No, sir. Could you explain to me why you didn't understand? No, sir. So if you talk to a machine using machine language, the

machine can understand it directly, right? So we see examples of some of the Oneji computers, which generation of computers are there, such as Mark One. Mark One is called the first electronic computer. So which is the first electronic computer? Mark One. Mark One. And the inventor of Mark One is the inventor. Who was the inventor?

I can Howard I can, who we know as the inventor of computers, and if we say the inventor is the company, then we would say IBM International Business Machines.

So which company made the first computer ?

Who was the inventor of the IBM computer?

What can I say if I understand the company? IBM.

Okay [clearing throat] Then came the first digital computer. So which was the first digital computer? The first digital computer? The first EDISAC. The first computer with memory. The first storable computer. S

for storage. S for storage. Mercury delay lines. Mercury delay lines.

ABC. The first automated computer. The first automated computer. These are all used by people. The first computer that came into the hands of people was the UNIVAC. Univac One and Two. The first commercial computer.

Sir, please tell me the number below number three. The

number four is ABC and the number three is storage, so which is the first computer with memory ? The

first computer with memory.

What were the first commercial computers?

Back one two

okay sir ok come now then what is the problem of the first generation size is it big or small? Big. Sir. So we will not try to solve this problem. Yes, sir. That's why we slowly moved to Tuji. The important feature of the 2G is that we built computers with transistors instead of vacuum tubes.

With what? Transistor. The inventor of the transistor was William Skoley, William Skoley, Walter Batten, and many others were team leaders. That's why William Skoley is called the inventor of this transistor. The year was 1947, if not in the option, then 1948. And where is it? Bell Laboratories, which is located in the United States.

And what is the function of a transistor? And before that, let me write a little bit about the transistor being made using silicon technology. Silicon technology. Silica comes from silica and means sand. Silica means sand. Sand. And what does the amount of this silicon in our body consist of, 27.7%, that is, 28%?

Silicone. This silicon combines with oxygen to form silicon dioxide. Which is what makes glass. I hope you can now recognize silicone. And it is a semiconductor. What is this transistor made of? What is the function of a transistor? There is a beautiful relationship between the work of transistors and our studies. You will see that our

studies are first motivated and at this level, slowly and gradually, you can't hear what you see and what you don't hear. That is, when your studies are over, you will see that you will put transistors in again, will it go to high amplitude again, will it produce results, will you put transistors in again? So

without transistors, it is not possible to take your studies forward at a faster pace. So what is the function of transistors? Signal amplification, signal amplification, or signal amplifier,

how far are you in working as an amplifier?

This is the last one, sir, don't do anything. Now computers have started being made with transistors. Give the heading of the first transistor-based computer. Give the heading of the first transistor-based computer. T.A. This is the first transistor- based computer. So which is the first transistor-based computer? T.X.Zero transistor, experimental zero

transistor, experimental zero computer. So here we have computers in Bangladesh. The

first computer in Bangladesh was IBM 1620.

IBM 1620. Bangladesh Atomic Energy Commission or Bangladesh Atomic Energy Commission [snort]

It came in 1964. Later, another computer was brought. Bangladesh, BUET, sorry, where did the IBM 1400 model come to Adamji Jute Mill? Adamji Jute Mill in 1965.

And remember, these two computers were main frame computers. So which are the main frame computers, sir?

Atomic Peace Commission. That is the Energy Commission. Yes, the Energy Commission. Atomic Energy Commission. What year was it? 1964.

And since then, it has been coming.

Yes, sir. So what type of computers were the first two in Bangladesh? Main frame. Mainframe computer. The first two computers to arrive in Bangladesh are the mainframe series.

Then we went to 3G. What else does a 3G computer need to do? What to do in a short performance? Hi. Which is why a group of scientists packed millions of transistors into a tiny silicon chip. The name is IC. Integrated circuits. Integrated circuits. So here it's not just IC, but IC is the

main component of IC, the transistor. Main ingredient. There were two other ingredients with it. One is a capacitor. Another one is the register. So do you remember how transistors work? Signal amplifier. The function of a capacitor is to hold charge. That's why we call it a charge carrier.

So what does IC consist of?

So how many elements are there in a layer capacitor resistor?

Sir, the writing is finished. Very good. So which is the fastest memory ? What is the register, madam, he said slowly, I am afraid, register, 3G technology, 3G, there are some technologies, the names of these technologies are like SSL, LSI, MSIS, S for Small Scale Integration, L for Large Scale Integration, M Medium,

Medium Scale Integration, R IC, personal first computer, PDP One, first IC based computer, PDP One,

first IC based computer in Bangladesh,

IBM System P Six, who came to BUET, came in

1900, 89, sorry, in 79, if it is

written, you will say that this computer is coming to Bangladesh, which is IBM System 360, the computer is mini frame, if it is

written, you will say.

So what happened to the boys who finished writing?

Sir, okay,

finish writing. Sir, I am telling you that IBM System 360 is what kind of computer? 3G technology? 3G technology? Mini computer? Mini frame?

Okay, so what kind of computer came to Bangladesh? It

was the fastest, sir. Yes, he said, the fastest, temporary, practical. Explain it a little. That is volatile memory register. It is inside our processor. Where is it inside the processor? We will know tomorrow. I think we have a class with you. It seems like sir. It is not permanent. It does not erase.

Something like that. What else is volatile? It is volatile. It means it erases. Temporary. It erases. What happens to memory when the power goes out? When the power goes out, the memory is erased. Rob, who says that

you have a head, it is inside the head. It is not like our brain is like this. Yes, it is not like this. There is no need to see the brain. Yes, sir, there is a memory in the middle of this brain. This is how arithmetic works. And it works logically. And the part in the middle here is

this register. This register is called the Hippo Campus in our brain language. Hippo Campus. And the work of Hippo Campus is to see two parts of data A and L. But this is intellectual work. It works logically. The result of these two is stored in a register and is transferred from the register to the output. Okay?

So now everything that goes into this register, that is, everything that goes to the Hippo campus, is deleted. Which is why you study and get wiped out. Isn't that true? What else do you do after reading? I want to die. Don't forget ? Read and don't forget? Sir. Again, most people's A and L do

n't work together. This means that not everyone's cognitive and logical functions work together. And those who do n't suffer from indecision. Such a patient. Now, will you take a test and see who is in this problem? Huh. I will tell you.

Yes sir. There is a test for this on the Hippo Campus. Yes, an MRI test costs 13,000 to 15,000 taka. You will know by doing that test. So now it will take so much money. I'll let you know the test results, okay? No need to test. The automatic result will be out. For

example, if these girls think a little, many times when there is a fight, the real thing is not remembered at the end of the fight. Time does not come to mind. So when you remember the real thing at the end of the fight, you should understand that one part of you is working and the other

part is not working. It means that time is running out to do that and because of this imbalance, you are not able to say the real thing at the right place.

So now see if studying with this problem in mind will take more or less time? If you study this disease, then someone else will not have this disease. Will you get a job before him? G Sir, let's say that he is thinking about his brain, meaning he is coming up with answers and you are

thinking that since you have this problem in your head, then you are thinking like this, B and A are thinking between the two options, like this, of course B will be the answer, B will be the answer, B will be the answer, B will be the answer, what do you think, A will be the answer B will be the answer, B will be the answer, B will be the answer, B will be the answer, B will be the answer, B will be the answer, B will be the answer, I do

n't think so, I would have said that in Bida, but did I remember that at that time, I went shopping and walked around for four or five hours, and when I came home with the dress, I didn't think that was good. G, the problem of bringing this up, now you have an idea about the register,

remember that it is the register, what is after the register, is the cache memory, which is after the cache, ROM, which is after the ROM, SSD, finally if HDD keeps going up, the price and speed will increase. Prices and speeds increase. So which memory is the most expansive?

Which one is the Expensive Star and which one is the Faster? If the speed is higher, the price will be higher.

If the speed is higher, the price will be higher.

If the

speed is higher, the price will be higher. Listen, what will be the price if the speed is higher?

If the speed is higher, the price will increase. So which memory has the lowest storage capacity and which has the highest speed? So tell me, between SSD and HD DD, which one has the highest speed? SSD is faster. Now they say they are having trouble with memory. This trouble is gone. What are

the names of all the memories? Yes. These are all memories. Register, cache, ROM, SSD, HD Yes sir, sir, we always talk about ROM, SSD, HD, but where is the register cache used? It is inside the processor. Okay, sir. And inside the CPU box, RAM is installed on the motherboard. Yes, SSD. And your

HD. You install these separately. But the register and cache are inside the processor. It is understood that these are stored. We will go to class number three or four and learn about them again. Yes, in detail, today you were having a little problem, so I will show it separately. Let's go to the forge.

Which generation of computers do we currently use? The notable feature of the fake computer is the microprocessor. Microprocessor. And the microprocessor is made of millions of ICs. And what are the components of IC? What are the main ingredients? No transistor? Transistor. So now what is the smallest, smallest element? Transistor. Transistor. So what is the

smallest component that a microprocessor is made of? Transistor. Do you

understand? Yes, sir. We will take a break for prayers. Okay. Yes, sir. What time will it start again? No, no, no. I'll brake once. I mean, you have to take a break and start again, right? We'll leave it at once. Okay. Finish it at once. That will happen. So there are transistors inside the microprocessor,

right? And the inventor who created this microprocessor is named Ted Hopp. Ted Ted. Yes. In 1975, we were at war. And the inventor company here was Intel. What is the name? Intel Company. So who is doing all the financial and spiritual transactions that need to be done? Intel. And who is working with talent for money

? I will trade. Which seems to be causing Intel a problem. When you say microprocessor inside the microprocessor, the name Intel comes up. The name comes up. I made something myself, but it doesn't feel bad if it doesn't have its own name. That's why the name of the microprocessor is changed to Intel 4004.

This is the first microprocessor. So what is the name of the first microprocessor? Intel and the first computer was made with Intel 4004. The first computer was made with the Altair computer. The Altair 8800 was the first microprocessor-based computer. But

sir, the writing is over. How are the boys?

These guys don't talk, yes everyone seems to be sir, yes everyone, and here the name of the technology is VLSI V for Very, then the full form will be Very Large Scale Integration, Large Scale Integration, let's go, let's go to

5G, what will 5G be like, then in the future computer, then what will the future computer be like, the technology will be technology, UVLSI, I am writing it with Ultra U, the rest is written here above, Ultra Very Large Scale Integration, Ultra Very Large Scale Integration, and the notable feature here is AI AI

Artificial Intelligence, is it a simulation of the human brain, simulation of the human brain, do you think the intelligence or brain of the machine is good ?

This machine is a simulation of the human brain. Yes, simulation of the human brain.

Then write a little bit about the father of AI, John Makharth,

before that. Okay, sir, that's what I'm writing.

What did the Father of AI say? John McCarthy, please write a little. Hey, Makharthi writes in Bengali. It has been

written, sir, that if John McArthur, the father of AA, were to

talk about any subject in front of a mobile phone, he would find that the mobile phone could not hear him. And it can be heard through voice recognizer. And as soon as you listen, you'll see ads showing up on the topic you're talking about. Are you paying attention?

Now look, we can see our mobile phones. Okay? Through face recognition. These are all 5G technologies. Pace Recognition. We can see everything through the webcams in front of us. There is another thing, which is neural networks. Neural network. And with this neural network, you can connect your brain to your brain through sensors. That means your mobile phone can

automatically connect to your brain. Brain to device. Brain to device. See if when you think about something in your mind, that topic comes to mind or not? Yes, sir. Are n't you thinking about taking a course after you've been admitted to Vidyabari ? Yes

sir, I have finished writing.

Another important feature will be IoT. Internet of Things. IoT. Internet of Things. The technologies I've mentioned so far all combine to form IoT. IoT equals AI plus VR plus augmented reality augmented reality

plus ETC

Sir, what did you write next? ATC OK,

sir, so this is the fifth generation. We move on to the classification of computers. You do n't understand this a bit. Sir, come on, come on, from above, what do you say about the fifth generation? What is the fifth generation technology? UV LSI Ultra Very Large Scale Integration. Okay, the next important feature is AI.

What is AI? Artificial Intelligence. AI is Artificial Intelligence. Clear? What is this? Simulation of the human brain. Simulation of the human brain. Brain

What's next? Look at voice recognition. Now, if you talk on your mobile or in front of your computer, you will see that it automatically shows an advertisement about the topic or subject you were talking about. This means that you did not input the words. Again, look at the font camera in front of you, the font

camera on the front of the mobile, but it can see you and because it can see you, it can see you. It

processes your augmented reality and analyzes your appearance and shows you what you like and what you don't like. When you watch a reel video, you think you saw a video and you like it. Later, you will see it and show you some more videos of that same video. Are you paying attention? Yes, sir. I see, that's okay, sir.

That means he's watching through that camera whether you're enjoying it or not.

They will show you what they seem to enjoy watching over and over again. Now look at the next technology, which is neural networks. You don't need to see it, you do n't need to hear it. You just have to think about it in your mind. That's it. Many of you may have been admitted to Vidyabari.

Thinking about taking a course? And the advertisement for Vidyabari appeared. Isn't that what happened

? Say this.

Yes sir, now I understand, yes I understand clearly, let's

go now, how many types of computers are there in the classification of computers, let's

talk about three types, sir, what is

analog, digital, hybrid, sir, let's

go, we know the details, okay, this is it [clearing throat], five minutes, pray, I will also read now. I know a little about computers. Yes. There are actually two types of computers. One is a special computer. Special computer. Yes, yes, you will write. Special is embedded computer [clears throat] Another is general special and general. So how many

types of computers are there? What are the two main types?

Microcontroller based or based ICs such as ATM calculators micro pro web oven AC fan CD player etc. robots etc. [Clearing throat] So what is a microcontroller based IC called? The

writing is over,

now comes the general computer, again there are three types depending on the application, one is analog, the other is digital, the accuracy of digital is 100 percent, and the combination of these two has created another one, that is, hybrid. What is hybrid? Now comes the digital computer, again there are four types of

super computers. A while ago, I was reading the main frame. I remember that there are

four types of digital computers based on the size, capacity and efficiency of mini micro or PC. These four types are super main, mini micro, micro or PC, personal computer, but among the examples, you will find desktop,

laptop, roll top, palmtop,

palmtop, which is a computer that can be used in the palm of your hand, and another is the tablet, which is also called tablet PC or hand- held computer that is used in the palm of your hand. Do you understand? Now tell me, what other types of computers are you having problems with? Is

this true or not? Okay, then write to me and tell me, sir, how many microcomputers are there, tablet PCs, handheld computers, which are suitable for use in the palm of your hand, which are like the top chats on Plumtub, so that's the

end, sir.

This is the end [clearing throat] The

end Sir I ca

n't hear this The end Yes Sir The end So that's it for today Yes Do you have any comments about the class Are you feeling bad Not feeling good Tell me how it is Feeling good Sir Not feeling good Yes Sir Feeling good Okay Thank you See you again in the next class

Inshallah The end Okay Allah Hafez Allah Hafez Assalamu Alaikum Walaikum Assalamu Ladies, please don't say anything Assalamu Alaikum Sir Feeling good Yes Sir Okay Pray for me Allah Hafez
