What is the ASCII table?
ASCII (American Standard Code for Information Interchange) was born in 1963 as a character encoding standard. There are 128 characters in total (0–127): 33 of them are control characters that don't print, and the other 95 are printable, including letters, digits and punctuation symbols.
Each character maps to a decimal code. The letter A, for instance, is code 65 (41 in hex, 01000001 in binary). Programming, network protocols and operating systems rely on these codes all the time.
Worth remembering that ASCII is part of Unicode, since the first 128 Unicode code points line up exactly with the ASCII table.

Complete ASCII table for reference
Sooner or later, anyone who codes, deals with protocols or studies computing ends up needing to look up an ASCII character's code. This table lays out all 128 characters of the standard, each one with its code in decimal, hexadecimal and binary, plus the HTML entity and a short note on what it represents.
Filter by type to split control characters (line break, tab and the like) from printable ones. When you already know what you're after, search straight by the character or the code. It backs you up while converting, debugging data or making sense of that odd byte that turned up in a file.
All of it lives in the browser, no memorising and no manual to crack open. A reference that fits the everyday work of building and studying.
