The ASCII table narrates a historical tale of encoding practices throughout the history of computer science. You aren't likely to lose your job over not being able to recite ASCII character codes—but you *might* lose it over not knowing how to look them up. Print this chart out, place it above your desk, and keep that paycheck rolling in! Printable ASCII Table (Click to Enlarge) ASCII Table The American Standard Code for Information Interchange (ASCII) is a means of encoding characters for digital communications. It was originally developed in the early 1960s as early networked communications were being developed. A Control Characters Note the first 32 characters, decimal values 0-31, have been reserved for non-display characters. These are referred to as control characters and were originally intended as machine control signals to trigger events like system sounds (beep), network acknowledgments (ACK), and end of text (EOT). Printable Characters The ASCII-encoded characters for decimal values 0-31 do not print or render to displays like other characters. As such, attempting to use these characters for non-control functions typically results in the display of a default missing character symbol or other unwanted (and irrelevant) characters. Modern Expanded ASCII With the rise of 16, 32, and 64-bit machines, ASCII has seen several significant expansions over the years. The first expansion, called extended ASCII, used an 8-bit representation and extended to the range of 0-255...

Before discussing how you could memorize a table of ASCII characters and numeric values, I should say a little about why you might do so. One reason is simply for the challenge. It’s more doable than it may sound. It’s also useful information, though it’s debatable whether it’s worth memorizing. YMMV. There was a time early in my career when I spent a lot of time staring at a hex editor, and it definitely would have been useful to know then. I still need to look up ASCII values occasionally, though not as often. One step in the process of memorizing the ASCII table is to associate an image with each ASCII character. This is useful by itself without learning the ASCII values of the characters. You could memorize strong passwords, for example, by linking together the images associated with each character. I’ll only consider printable characters in this post. ASCII landmarks It’s very handy to know that the ASCII code for 0 is 48 and that the digits codes are in order. So the ASCII code for the digit d is d+48. Wouldn’t it have been easier if the digits started at a location ending in zero? They do, in hexadecimal: digits start at 0x30. Similarly, capital letters start at 65 (or 0x41). So the nth capital letter starts at n+64 (or n+0x40). Lower case letters start at 97 (0x61), and so the nth lower case letter starts at n+96 (or n+0x60). Incidentally, you’ll sometimes see software that sorts capital letters before lower case letters. The software is probably simply sorting by ...

ASCII (American Standard Code for Information Interchange) is a standard character encoding used in telecommunication. The ASCII pronounced ‘ask-ee’, is strictly a seven-bit code based on the English alphabet. ASCII codes are used to represent alphanumeric data. The code was first published as a standard in 1967. it was subsequently updated and published as ANSI X3.4-1968, then as ANSI X3.4-1977, and finally as ANSI X3.4-1986. Since it is a seven-bit code, it can at the most represent 128 characters. it currently defines 95 printable characters including 26 upper case letters (A to Z), 26 lower case letters, 10 numerals (0 to 9), and 33 special characters including mathematical symbols, punctuation marks and space characters. They represent text in, telecommunications equipment, and devices. These include numbers, upper and lowercase English letters, functions, punctuation symbols, and some other symbols. In total, there are 256 ASCII characters, and can be broadly divided into three categories: • ASCII control characters (0-31 and 127) • ASCII printable characters (32-126) (most commonly referred to) • Extended ASCII characters (128-255) Below are the ASCII values of printable characters (33, 126):, Character Character Name ASCII code !
