How does the computer work?

We will now know how our computer's name machine does all the work as our instruction. When we press a key from the computer's keyboard, almost all of the letters or numbers we want are being displayed on the monitor screen. It is computer but we do not know Characters or numbers do not understand anything. To him, only two numbers are known. That is - '1' and '0' With this 1 and 0, the computer displays all our information or instruction on the monitor screen. Again, this is 0 and 1 number, but the computer is different. Computer understands 0 means 'no' and 1 means 'yes', in other sense 0 means off Off) and 1 means on (on) Suppose, there is an electric table lamp and a switch of it. When the switch will be turned on the lamp, then the lamp will be off when turned off. It is such that the lamp does not shine or it will not be there any way or arrangement in the middle of it. In such a system, the computer performs all its functions. He will understand it off, otherwise it will understand. That is, 0 means that it is understandable that we can understand nothing in the outside or in the middle of our computer. These two numbers are called binary numbers. In computer languages, the binary number of binary lamps and the binary being taken by the binary is 0 - 0 binary numbers = no = Off and 1 binary number = yes = on Unbelievably, when the computer is in motion, the high-speed current flows through a microprocessor installed on the small silicon chips inside it. This flow creates a variety of vibrations - which is called Pulse in English and the code or code generated from this pulse. This code number is called eski or escai code. Computer can not recognize any letter directly or not recognize him. Each number or character has different codes for it. This code number is created again by 0 and 1. For each letter or number of keyboards, there are eight binary numbers individually arranged - a code that is created with. The interesting thing is, these signals of Pulse are created, but the transistors installed on the chips. These transistors usually work as an on-off switch of the table lamp. That is, sometimes the circuit current flows out of the current flow, and it turns out to be faster than this. The transitists are doing this work faster than a decade or so. By this, the computer will recognize the binary number 0 and 1. If there is another example in this context, the matter will be a bit clearer. What happens when telephony talks between two customers? As you speak from one end to the other, it is heard on the other side. There is a lot of things happening in this saying and listening that we can not understand. As the customer speaks on one end, the words are changed with high amounts of electricity or electricity. Again, this electrical wave is changing on the other side before reaching the ear of the customer, in the sound wave. But the whole thing is happening with the help of pulse. That means, on the off and on, its pulse or pulse. It is such a word-> power-> sound. In such a arranged way, the communication between the ends of the customer from one end to the other in the telephone. Our computer machine makes a word or letter similar to that on its monitor screen. When the keyboard is transformed into electricity, immediately after a suspension or letter key is pressed. At the moment, the electricity is changing in our known characters or numbers. And on the monitor screen. That means - Characters> Power> Characters. But this process is going to be another process. Whenever a letter or number key is pressed from the keyboard, the cursed letter or number is being turned into electricity and only then the pulse is being created. That is the pulse of on and off. This spell is being reproduced in binary numbers. Code or signals are created. Computer binary numbers in this sign are matching, with the code number already placed in it. This is when the monitor is showing the monitor screen. So many things happen but in the end. When the English letter 'A' of the keyboard is pressed, the letter 'A' appears on the monitor screen. That means - Characters> Electricity> Binary numbers> Characters. Understand the computer with eight binary numbers arranged differently for each letter or number. This binary number is called Bit. A code is generated by eight binary numbers, it is called byte. In order to form a character, eight binary numbers take a bit - so a letter is said to be a byte. We understand the computer as a single character Understand as a byte. Thus, for each character, different 8 binary numbers are arranged. The 8 binary numbers are thus arranged in 256 shapes. However, we do not have English or Bangla letters 256. So it is possible to arrange the characters in different binary numbers. Binary methods and numbers count: Generally, the numbers used in mathematics are called decimal numbers. This decimal number system has ten numbers. A group of these numbers have been formed based on ten. All of the solutions are given by the ten numbers. Consider 50 and 60 numbers as well. Here is 10 times 5 times 50 and 6 is 10 times 60. Here is a decimal number with numbers from 0 to 9. Here we used 9, 0, 4, 1 numbers to write this number 9041. Here is another way but it is not
