ASCII
On mobile phones, many binary values listed here will be interpreted as phone numbers. This gives them a blue, clickable link.
ASCII is a special way of encoding characters, which was mainly used in the 1960s-1970s, and more recently it has been used in EsoLangs. ASCII stands for American Standard Code for Information Interchange. ASCII uses 8 binary digits (bits) to represent characters: 1000001 (65) represents the upper-case letter A; 1000010 represents B; 1000011 represents C; and so on in sequence.
Eight bits allowed a parity bit to be included in each byte sent over a serial port or modems, this bit is used for avoiding errors. This was more important years ago when connections were often noisy.
For esolangs, most of ASCII before 32 won't be relevant. The main pre-32 characters are NULL and new line.
