ASCIIkoodit

ASCIIkoodit, often referred to as ASCII codes, are a character encoding standard that uses numeric values to represent characters. ASCII stands for American Standard Code for Information Interchange. It was first published in 1963 and has since undergone several revisions. The original ASCII standard used seven bits to represent characters, allowing for 128 unique characters. These included uppercase and lowercase English letters, digits 0-9, punctuation marks, and various control characters.

Later, an extended ASCII standard was developed, using eight bits to represent 256 characters. This extension allowed for additional characters, including accented letters, graphic symbols, and special characters, which varied depending on the specific implementation or code page. While influential, ASCII has largely been superseded by more comprehensive encoding schemes like Unicode, which can represent characters from virtually all writing systems in the world. However, ASCII remains foundational, and its first 128 characters are a subset of Unicode, ensuring backward compatibility. Understanding ASCIIkoodit is fundamental to comprehending how text is represented and processed in computing systems, especially in older or simpler applications.
