Cyclic redundancy check. A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [ 1][ 2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.
It must be noticed that not all systems using 16-bit color depth employ the 16-bit, 32-64-32 level RGB palette. Platforms like the Sharp X68000 home computer or the Neo Geo video game console employs the 15-bit RGB palette (5 bits are used for red, green, and blue), but the last bit specifies a less significant intensity or luminance.
A display resolution standard is a commonly used width and height dimension (display resolution) of an electronic visual display device, measured in pixels. This information is used for electronic devices such as a computer monitor. Certain combinations of width and height are standardized (e.g. by VESA [ 1][ 2]) and typically given a name and ...
In the last five years, six U.S. localities, including New Orleans and Clark County, Nevada, have adopted such cooling laws, compared with just seven in the previous two decades, according to ...
In the United States a longer duty cycle is used, 50% for battery-powered buoys (20 seconds on, 20 seconds off) and 75% for on-shore beacons. Ramarks are wide-band beacons which transmit continuously on the radar bands without having to be triggered by an incoming radar signal. The transmission forms a line of Morse characters on the display ...
AMD Athlon (early version), a technically different but fully compatible x86 implementation. x86 (also known as 80x86[ 3] or the 8086 family[ 4]) is a family of complex instruction set computer (CISC) instruction set architectures [ a] initially developed by Intel based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
In a United States presidential election, the popular vote is the total number or the percentage of votes cast for a candidate by voters in the 50 states and Washington, D.C.; the candidate who gains the most votes nationwide is said to have won the popular vote. However, the popular vote is not used to determine who is elected as the nation's ...
