How many bits (binary digits) does a character have?
(A) 2 bits
(B) 4 bits
(C) 6 bits
(D) 8 bits
Standard byte either 8-bit or octet represents character in modern computing, resulting in 256 possible character combinations. Original ASCII was 7-bits and had 128 characters, whereas most modern systems used 8-bit codes (either extended ASCII or UTF-8) which means that most letters, numbers and symbols have 256 unique values. Basic standard Unicode uses a single unit consisting of either 16 or 32 bits; however, 8 bits remains basic unit for representing a character in typical encoding scheme.
