What is the size of each ASCII character in bits?
8 bits
Each ASCII (American Standard Code for Information Interchange) character is represented using 7 bits.
However, in most modern computer systems, ASCII characters are typically stored in 8-bit bytes (1 byte), where the extra 8th bit is often used for parity (error checking) or simply left as 0 in standard ASCII.
Breakdown:
- Standard ASCII: Uses 7 bits, allowing 128 unique characters (0 to 127).
- Extended ASCII: Uses 8 bits, allowing 256 characters (0 to 255), commonly used in different character encoding schemes like ISO-8859-1.
Thus, while the official ASCII standard only requires 7 bits per character, it is generally stored using 8 bits (1 byte) per character in most computing systems.
