Parity bit 1 covers all bit positions which have the least significant bit set: bit 1 (the parity bit itself), 3, 5, 7, 9, etc. Parity bit 2 covers all bit positions which have the second least significant bit set: bits 2-3, 6-7, 10-11, etc.

A bit array (also known as bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits.It can be used to implement a simple set data structure.A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly. A typical bit array stores kw bits, where w is the number of bits in the unit of storage, such as a byte or ...

The Lempel–Ziv–Markov chain algorithm (LZMA) is an algorithm used to perform lossless data compression.It has been under development since either 1996 or 1998 by Igor Pavlov and was first used in the 7z format of the 7-Zip archiver. This algorithm uses a dictionary compression scheme somewhat similar to the LZ77 algorithm published by Abraham Lempel and Jacob Ziv …

Alpha (original name Alpha AXP) is a 64-bit reduced instruction set computer (RISC) instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). Alpha was designed to replace 32-bit VAX complex instruction set computers (CISC) and to be a highly competitive RISC processor for Unix workstations and similar markets.. Alpha is implemented in a series of …

Binary representation. A PCM signal is a sequence of digital audio samples containing the data providing the necessary information to reconstruct the original analog signal.Each sample represents the amplitude of the signal at a specific point in time, and the samples are uniformly spaced in time. The amplitude is the only information explicitly stored in the sample, and it is …

Theory. Two's complement is an example of a radix complement.The 'two' in the name refers to the term which, expanded fully in an N-bit system, is actually "two to the power of N" - 2 N (the only case where exactly 'two' would be produced in this term is N = 1, so for a 1-bit system, but these don't have capacity for both a sign and a zero), and it is only this full term in respect to …

A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.Most CPUs have a hierarchy of multiple cache levels …

A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.Within the Open Systems Interconnection (OSI) network model, MAC …

In computing, endianness is the order or sequence of bytes of a word of digital data in computer memory.Endianness is primarily expressed as big-endian (BE) or little-endian (LE).A big-endian system stores the most significant byte of a word at the smallest memory address and the least significant byte at the largest. A little-endian system, in contrast, stores the least-significant …

Data structure alignment is the way data is arranged and accessed in computer memory.It consists of three separate but related issues: data alignment, data structure padding, and packing. The CPU in modern computer hardware performs reads and writes to memory most efficiently when the data is naturally aligned, which generally means that the data's memory address is a …

Instruction ROM is 24 bits wide. Software can access ROM in 16-bit words, where even words hold the least significant 16 bits of each instruction, and odd words hold the most significant 8 bits. The high half of odd words reads as zero. The program counter is 23 bits wide, but the least significant bit is always 0, so there are 22 modifiable bits.

Empfängergruppe. Das niederwertigste Bit (engl. Least Significant Bit, LSB) des ersten Bytes (Bit 0) einer MAC-Adresse gibt an, ob es sich um eine Einzeladresse oder Gruppenadresse (I/G für Individual/Group) handelt.Bei einem Broadcast oder Multicast wird I/G = 1 gesetzt, sonst und bei Quelladressen ist I/G = 0.. Kurz: I/G ist 0 für I (Individual) oder

x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit version of the x86 instruction set, first released in 1999.It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode.. With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than was …

A parity bit, or check bit, is a bit added to a string of binary code. ... can be determined just by examining only its least significant bit. In information technology parity refers to the evenness or oddness, given any set of binary digits, of the number of those bits with value one. Because parity is determined by the state of every one of ...
