Understanding ASCII
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric codes to letters, numbers, symbols, and control characters. The standard ASCII table contains 128 characters (0-127), while extended ASCII adds another 128 characters (128-255) for international and special symbols.
ASCII Character Categories
- Control Characters (0-31, 127): Non-printable characters used for text formatting and device control, like newline, tab, and carriage return.
- Printable Characters (32-126): Visible characters including letters, numbers, punctuation, and symbols commonly used in text.
- Extended ASCII (128-255): Additional characters for international alphabets, currency symbols, and graphical elements.
Common ASCII Values
- Space: Decimal 32, Hex 0x20
- Numbers 0-9: Decimal 48-57, Hex 0x30-0x39
- Uppercase A-Z: Decimal 65-90, Hex 0x41-0x5A
- Lowercase a-z: Decimal 97-122, Hex 0x61-0x7A
- Newline (LF): Decimal 10, Hex 0x0A
- Carriage Return (CR): Decimal 13, Hex 0x0D
Frequently Asked Questions
What's the difference between ASCII and Unicode?
ASCII is a 7-bit encoding with 128 characters, while Unicode is a much larger standard supporting over 140,000 characters from all world languages. ASCII is a subset of Unicode (the first 128 characters are identical).
Why are there control characters?
Control characters (0-31 and 127) were originally designed for controlling teletype machines and terminals. Many are still used today, like Tab (9), Line Feed (10), and Carriage Return (13).
What is extended ASCII?
Extended ASCII uses the eighth bit to represent characters 128-255, adding support for international characters, currency symbols, and box-drawing characters. The exact characters vary by encoding (like ISO-8859-1 or Windows-1252).
