# ASCII table [ASCII](https://en.wikipedia.org/wiki/ASCII) abbreviated from *American Standard Code for Information Interchange*, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters. ASCII is used to map characters to 7 bit wide integers and vice versa. ## Control Characters The first 32 characters cannot be printed and are used purely for control. | Decimal | Octal | Hexadecimal | Binary | Symbol | Description | | :-----: | :---: | :---------: | :------: | :----: | :----------------------: | | 0 | 000 | 00 | 00000000 | NUL | Null Char | | 1 | 001 | 01 | 00000001 | SOH | Start of Heading | | 2 | 002 | 02 | 00000010 | STX | Start of Text | | 3 | 003 | 03 | 00000011 | ETX | End of Text | | 4 | 004 | 04 | 00000100 | EOT | End of Transmission | | 5 | 005 | 05 | 00000101 | ENQ | Enquiry | | 6 | 006 | 06 | 00000110 | ACK | Acknowledgement | | 7 | 007 | 07 | 00000111 | BEL | Bell | | 8 | 010 | 08 | 00001000 | BS | Backspace | | 9 | 011 | 09 | 00001001 | HT | Horizontal Tab | | 10 | 012 | 0A | 00001010 | LF | New Line (Line Feed) | | 11 | 013 | 0B | 00001011 | VT | Vertical Tab | | 12 | 014 | 0C | 00001100 | FF | Form Feed | | 13 | 015 | 0D | 00001101 | CR | Carriage Return | | 14 | 016 | 0E | 00001110 | SO | Shift Out | | 15 | 017 | 0F | 00001111 | SI | Shift In | | 16 | 020 | 10 | 00010000 | DLE | Data Line Escape | | 17 | 021 | 11 | 00010001 | DC1 | Device Control 1 (XON) | | 18 | 022 | 12 | 00010010 | DC2 | Device Control 2 | | 19 | 023 | 13 | 00010011 | DC3 | Device Control 3 (XOFF) | | 20 | 024 | 14 | 00010100 | DC4 | Device Control 4 | | 21 | 025 | 15 | 00010101 | NAK | Negative Acknowledgement | | 22 | 026 | 16 | 00010110 | SYN | Synchronous Idle | | 23 | 027 | 17 | 00010111 | ETB | End of Transmint Block | | 24 | 030 | 18 | 00011000 | CAN | Cancel | | 25 | 031 | 19 | 00011001 | EM | End Of Medium | | 26 | 032 | 1A | 00011010 | SUB | Substitute | | 27 | 033 | 1B | 00011011 | ESC | Escape | | 28 | 034 | 1C | 00011100 | FS | File Seperator | | 29 | 035 | 1D | 00011101 | GS | Group Seperator | | 30 | 036 | 1E | 00011110 | RS | Record Seperator | | 31 | 037 | 1F | 00011111 | US | Unit Seperator | ## Printable Characters The codes 32 - 127 are all the printable characters.
