Code | What is coding in computer?

Hi, I'm Golam Rabbani. Today I will discuss about Code.

Greetings! How are you all? Hope everyone is well.

Code is the English word. Whose Bengali meaning is a monograph (statute law). That is, if the unique meaning in some number of signals (0,1) is a statutory law, whose particular meaning is expressed in any digital device, then it is called code.

For example, it would be clear if the matter was explained. For example, if we type A on mobile or computer, we can see its output A. But what we actually did is put a, did not. Because A will first convert the computer to ASCII values. You already know that ASCII is a bits of 8 bits that have a specific value of 2 ^ 8 = 256, in which the upper English letters A = 65 to Z = 90 and the smaller hands are a = 97 to z = 122. Now this 65 will be converted to binary i.e. 01000001.

Before giving zero to zero, we all know that one by one (1) register in 8 bytes or 1 bits. That is, one byte of each binary number is one. If (0,1) how many bytes, the answer would be 2 bytes. Now 8 bytes = 1 bit. To make this one bit, the number of numbers needed before it is zero.
1 bit by 8 bytes, 1 kilobyte in 1024 bits, 1 megabyte in 1024 kilobytes, so giga, terra etc.

Now if we type this A character in HTML, then write the beginning and end.
A = & # 65; Z = & # 90 and a = & # 97; z = & # 122;
Copy the code and check the HTML file.

Thanks to everyone.
