| | Bit - Wikipedia, the free encyclopedia |
 | | In the IA-32 architecture, 16 bits are called a "word" (with 32 bits being a double word or dword), but other architectures have word sizes of 8, 32, 64, 80 or others. | | | The combination of the symbols "bit" for bit and "B" for byte is also widely used in computing, and is perhaps least ambiguous. | | | A bit refers to a digit in the binary numeral system (base 2). |

| | Bit Twiddling Hacks |
| | The counts of bits set in the bytes is done in parallel, and the sum total of the bits set in the bytes is computed by multiplying by 0x1010101 and shifting right 24 bits. | | | In 11 operations, this version interleaves bits of two bytes (rather than shorts, as in the other versions), but many of the operations are 64-bit multiplies so it isn't appropriate for all machines. | | | The most significant bit of the 4-bit representation is replicated sinistrally to fill in the destination when we convert to a representation with more bits; this is sign extending. |

| | What is bit? - A Word Definition From the Webopedia Computer Dictionary |
| | For example, classifying a computer as a 32-bit machine might mean that its data registers are 32 bits wide or that it uses 32 bits to identify each address in memory. | | | For example, a byte is composed of 8 consecutive bits. | | | This is Chapter 1 of Randall Hyde's book, "Art of Assembly Language." It describes the binary and hexadecimal numbering systems, binary data organization (bits, nibbles, bytes, words, and double words), signed and unsigned numbering systems, arithmetic, logical, shift, and rotate operations on binary values, bit fields and packed data, and the ASCII character set. |

| | DM's Esoteric Programming Languages - BIT |
| | BIT is a programming language in which the programmer has full access to all data in its essential machine representation. | | | Bit values may only be assigned to bit variables, and address-of-a-bit values may only be assigned to address-of-a-bit variables; anything else is an error. | | | It reads any number of bits from the input until a zero is read, then prints out the sequence of bits read in. |

| | Output of each bit map begins on a new line and will be in the same format as the input. | | | Output will consist of a series of bitmaps, one for each bit map of the input. | | | In the area of graphics, for example, a bitmap can represent an image by having a 1 represent a black pixel and a 0 represent a white pixel. |

| | The effort to port an application from 32 bits to 64 bits might range from trivial to very difficult, depending on how these applications were written and maintained. | | | As far as language implementation is concerned, the current C language standard allows the "long long" data type to be at least 64 bits. | | | As with UNIX® and other UNIX-like operating systems, Linux uses the LP64 standard, where pointers and long integers are 64 bits but regular integers remain 32-bit entities. |

| | Parity bit - Wikipedia, the free encyclopedia |
| | In computing and telecommunication, a parity bit is a binary digit that indicates whether the number of 1 bits in the preceding data was even or odd. | | | In serial communication contexts, parity is usually generated and checked by interface hardware (e.g., a UART) and, on reception, the result made available to the CPU (and so to, for instance, the operating system) via a status bit in a register in the interface hardware. | | | Parity checking is not very robust, since if the number of bits changed is even, the check bit will be valid and the error will not be detected. |

| | Since the OS plays a huge role in system performance by addressing and transferring data to and from memory, when the OS supports only 32-bits when the hardware supports 64 bits, the system is still somewhat limited. | | | To create a 64-bit driver, you must modify the DMA descriptors to address 64 bits of memory so the hardware can access the pointers to the data in this memory range. | | | During an address phase, AD[64::32] is used to send the upper 32-bits of a 64-bit address or during a data phase, an additional 32-bits of data. |

| | Bit rot - Wikipedia, the free encyclopedia |
| | Bit rot is a colloquial computing term used to facetiously describe the spontaneous degradation of a software program over time. | | | Bit rot can also be used to describe the very real phenomenon of data stored in EPROMs gradually decaying over the duration of many years, or in the decay of data stored on CD or DVD disks or other types of consumer storage. | | | Rarely, bit rot is referred to as the process by which data becomes inaccessible due to the lack of working devices to read old data storage formats. |
