Binary System

I understood that computers only understand the language of 0 and 1

So I needed a way to make the computer understand sounds, videos, images and languages

Therefore, symbols, numbers, and letters were converted into a value in the binary system, and this system is

ASCII code (American Standard Information Interchange)

 

As is clear in the previous image, this system provides each letter with a fixed value that the computer can understand

But this system is not sufficient because the data here represents only 7 bits or 8 bits

Because the maximum value I can reach is 255, assuming that there are 8 closed keys

But I cannot represent the rest of the multiple languages such as Arabic, Chinese, Japanese, and others

A new system called Unicode was invented, which can give you from 16 bits to 32 bits

  Computer language The computer only understands the language 1 and 0. Every letter I want to deliver to it has a specific code, and not just languages, but even pictures and videos. There are two systems for learning that language           Binary System                             Decimal System   I learned some basics about them, the most important of which is that each number has a specific value that is different from the other To represent any value, we must operate a number of switches to equal the same desired value For example, a binary system contains 8 keys, and each key represents  a value if it were the first key   It equals 1 and the second key equals 2 then If you want 1, I will open the first key If I want 2, I will open the second key If I want 3, I will o...

  Game I'm now starting to apply the concepts I've learned to designing a game. Each character will have its own code. We will have three characters, and I will add each character with its own commands The game will be like this

  Programming has many specializations such as web mobile desktop cyber security But first  we have to be properly established at the beginning of studying any language in a simple way, such as the CS50 curriculum The main idea of programming is to solve problems in the simplest way Firstly We have input, which is the problem to be solved The device in which we process   Output  of the solution to this problem In order to communicate with the computer to solve the problem, we must understand its language, which is the language of zero and one. The smallest computer unit is a bit The slightly larger unit is a byte, consisting of 8 bits The summary of all this is that every letter, number, or any word has a symbol for them in the language 0 or 1 We will learn more about how to communicate with the computer in this language in the coming days
