ASCII to binary

In a computer, all data is stored and calculated using a binary representation (because the computer uses high and low levels to represent 1 and 0, respectively). For example, 52 letters such as a, b, c, and d (including capitals), and numbers such as 0, 1, etc., as well as some commonly used symbols (such as *, #, @, etc.) are also represented in the computer using binary numbers, and which binary numbers are used to represent which symbols, of course, everyone can agree on their own set (this is called coding), and if everyone wants to communicate with each other without confusion, then everyone must use the same coding rules, so the relevant US standardization organizations have introduced ASCII codes. Uniformly specifies which binary symbols represent the above common symbols.
