ASCII - what is it?
ASCII stands for American Standard Code for Information Interchange.
- ASCII is a 7-Bit character encoding.
- The ASCII character encoding defines 128 characters.
- Including 95 printable and 33 non-printable characters, such as, for example, a line feed.
- Each character is assigned a Bit pattern of 7 bits.
- Each Bit can take two values, namely 0 or 1. This results in a bit pattern of the number of 2 States, high 7 Bits, for a total of 128 States results.
- A Byte is always 8-Bit. The ASCII not used, the eighth Bit can be used, for example, for error corrections. The parity bit is called.
- Today is the 7-Bit Code is extended almost always on an 8-Bit Code.
ASCII: What is this?
ASCII-encoding - this is how it works
If you want to encode the word "CHIP" in ASCII, then proceed as follows:
- You need an ASCII table.
- The word CHIP can be in hexadecimal or binary encoding.
- For a binary encoding of rows of the binary values of each letter one after the other. The following binary ASCII Code: 01000011010010000100100101010000 results
- For the hexadecimal encoding you need a more advanced table. Series you the hexadecimal values in the table, depending on the letter one by one. For the word CHIP with the following Code: 67727380 results
With your new Knowledge of the ASCII Code you can, for example, in Word, the character encoding change.
