Overview of ASCII tables

Because of the large number of characters that can be represented by ASCII code, it’s a good idea to consult a chart with the characters that can be represented by ASCII and the binary, decimal, and hexadecimal numbers representing these characters. The first two number systems are commonly used by humans and machines, respectively. The hexadecimal system, on the other hand, has the advantage of containing 16 characters (0-9 + A-F) and can represent larger numbers in fewer digits compared to the other systems. Thus a byte can be represented with a maximum of two digits.

For the sake of clarity, we’ll split control characters, that is characters which are not printed by the computer but represent commands such as a line break, and the printable characters into two separate tables.

ASCII table: extended version

Extended ASCII versions use an eighth bit, which is assigned differently from program to program. In most cases, the additional digit is used to accommodate country-specific peculiarities. The first 128 characters are always the same.

Below is an example of the ASCII extension Windows-1252 developed for the Windows operating system.

Fact

Besides ASCII, UTF-8 encoding is just as significant and near congruent.

Example: Convert ASCII characters

In ASCII, the system converts binary numbers into printable and non-printable characters according to a specified standard, as listed in the table above. Users can also perform these computational processes without any aids. All you have to do is understand how to calculate in binary or hexadecimal. In a number system, each digit corresponds to the power on a particular basis: in the decimal system, the base is 10. The bases are 2 and 16 for binary and hexadecimal systems, respectively. Multiply the value of the digit by the value of the digit.

Digit values in the decimal system:
