The byte, 8 bits, 2 nibbles, is possibly the most commonly known and used base unit to describe data size. The word is a size that varies by and has a special importance for a particular hardware context. On modern hardware, a word is typically 2, 4 or 8 bytes, but the size varies dramatically on older hardware.
– equivalent to 1 "word" on 16-bit computers (IBM PC, Commodore Amiga) – the "word size" for 16-bit console systems including: Sega Genesis, Super Nintendo, Mattel Intellivision. 2 5: 32 bits (4 bytes) – size of an integer capable of holding 4,294,967,296 different values – size of an IEEE 754 single-precision floating point number
The entire game uses only 97,280 bytes of disk space. In contrast, most contemporaneous first-person shooters filled one or more CDs or DVDs . [ 2 ] According to the developers, .kkrieger itself would take up around 200–300 MB of space if it had been stored the conventional way.
Using a data size of 16 bits will cause only the bottom 16 bits of the 32-bit general-purpose registers to be modified – the top 16 bits are left unchanged.) The default OperandSize and AddressSize to use for each instruction is given by the D bit of the segment descriptor of the current code segment - D=0 makes both 16-bit, D=1 makes both 32 ...
Because the byte size of eight bits is so common, but the definition is not standardized, the term octet is sometimes used to explicitly describe an eight bit sequence. A nibble (sometimes nybble), is a number composed of four bits. [4] Being a half-byte, the nibble was named as a play on words. A person may need several nibbles for one bite ...
An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The 4-bit processors were programmed in assembly language or Forth, e.g. "MARC4 Family of 4 bit Forth CPU" [6] (which is now discontinued) because of the extreme size constraint on programs and because common programming languages (for microcontrollers, 8-bit and larger), such as the C programming language, do not support 4-bit data types (C ...
