BER: variable-length big-endian binary representation (up to 2 2 1024 bits); PER Unaligned: a fixed number of bits if the integer type has a finite range; a variable number of bits otherwise; PER Aligned: a fixed number of bits if the integer type has a finite range and the size of the range is less than 65536; a variable number of octets ...
Gulliver's Travels by Jonathan Swift, the novel from which the term was coined. In computing, endianness is the order in which bytes within a word of digital data are transmitted over a data communication medium or addressed (by rising addresses) in computer memory, counting only byte significance compared to earliness.
00 = reserved; otherwise in 10 kHz units (0.01–655.35 MHz, little-endian). 2: Horizontal active pixels 8 lsbits (0–255) 3: Horizontal blanking pixels 8 lsbits (0–255) End of active to start of next active. 4: Bits 7–4: Horizontal active pixels 4 msbits (0–15) Bits 3–0: Horizontal blanking pixels 4 msbits (0–15) 5
The difference between big- and little-endian is the order of the four bytes of the integer being stored. The first diagram shows a computer using little-endian. This starts the storing of the integer with the least-significant byte, 0x0D, at address a, and ends with the most-significant byte, 0x0A, at address a + 3.
An architecture may use "big" or "little" endianness, or both, or be configurable to use either. Little-endian processors order bytes in memory with the least significant byte of a multi-byte value in the lowest-numbered memory location. Big-endian architectures instead arrange bytes with the most significant byte at the lowest-numbered address.
PEF files, used by the classic Mac OS and BeOS for PowerPC executables, contain the ASCII code for "Joy!" (4A 6F 79 21) as a prefix. TIFF files begin with either "II" or "MM" followed by 42 as a two-byte integer in little or big endian byte ordering. "II" is for Intel, which uses little endian byte ordering, so the magic number is 49 49 2A 00.
FourCC is written in big endian relative to the underlying ASCII character sequence, so that it appears in the correct byte order when read as a string. Many C compilers, including GCC, define a multi-character literal behavior of right-aligning to the least significant byte, so that '1234' becomes 0x3 1 3 2 3 3 3 4 in ASCII. [ 10 ]
The Joliet file system, used in CD-ROM media, encodes file names using UCS-2BE (up to sixty-four Unicode characters per file name). Python version 2.0 officially only used UCS-2 internally, but the UTF-8 decoder to "Unicode" produced correct UTF-16. There was also the ability to compile Python so that it used UTF-32 internally, this was ...
