In Mac OS X, being based on BSD's UNIX-like kernel, the system architecture is vastly different from that in the classic Mac OS, and an application crash cannot usually bring down the entire system.
Error-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, [11] [12] as well as for reliable storage in media such as flash memory, hard disk and RAM. [13] Error-correcting codes are usually distinguished between convolutional codes and block codes:
The advantage of choosing a primitive polynomial as the generator for a CRC code is that the resulting code has maximal total block length in the sense that all 1-bit errors within that block length have different remainders (also called syndromes) and therefore, since the remainder is a linear function of the block, the code can detect all 2 ...
The first public version of ZTerm was 0.9, which was released in 1992. Two major versions followed; 1.0 of April 1994 was a major release that added 16-color ANSI support instead of 8-color, user-selected fonts including Shift JIS support, Kermit protocol support, and auto-opening of downloaded files.
If the number of errors within a code word exceeds the error-correcting code's capability, it fails to recover the original code word. Interleaving alleviates this problem by shuffling source symbols across several code words, thereby creating a more uniform distribution of errors. [ 21 ]
Debugging NMIs have appeared in a number of forms, including the Apple Macintosh's "programmers' button", and certain key combinations on Sun workstations. With the introduction of Windows 2000 , Microsoft allowed the use of an NMI to cause a system to either break into a debugger , or dump the contents of memory to disk and reboot.
A PC-based OBD analysis tool that converts the OBD-II signals to serial data (USB or serial port) standard to PCs or Macs. The software then decodes the received data to a visual display. Many popular interfaces are based on the ELM327 or STN [41] OBD Interpreter ICs, both of which read all five generic OBD-II protocols. Some adapters now use ...
This system detects all single-digit errors and around 90% [citation needed] of transposition errors. 1, 3, 7, and 9 are used because they are coprime with 10, so changing any digit changes the check digit; using a coefficient that is divisible by 2 or 5 would lose information (because 5×0 = 5×2 = 5×4 = 5×6 = 5×8 = 0 modulo 10) and thus ...
