The CMOS RAM and the real-time clock have been integrated as a part of the southbridge chipset and they may not be standalone chips on modern motherboards. [4] [5] In turn, the southbridge has been integrated into a single Platform Controller Hub. Alternatively BIOS settings may be stored in the computer's Super I/O chip. [6]
One example is the Linux kernel's EDAC subsystem (previously known as Bluesmoke), which collects the data from error-checking-enabled components inside a computer system; besides collecting and reporting back the events related to ECC memory, it also supports other checksumming errors, including those detected on the PCI bus.
This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted.
The original IBM PC could be equipped with as little as 16 KB of RAM and typically had between 64 and 640 KB; depending on the amount of equipped memory, the computer's 4.77 MHz 8088 required between 5 seconds and 1.5 minutes to complete the POST and there was no way to skip it.
A file can become corrupted by a variety of ways: faulty storage media, errors in transmission, write errors during copying or moving, software bugs, and so on. Hash-based verification ensures that a file has not been corrupted by comparing the file's hash value to a previously calculated value. If these values match, the file is presumed to be ...
The touch keyboard no longer docks in screens larger than 18 inches. [1] Windows no longer synchronizes desktop wallpapers across devices with a Microsoft account. [1] Windows no longer shows a small preview of images or videos on folder thumbnails. Instead, it shows the generic folder icon for any folder containing images or videos. [5] [note 2
Electrical or magnetic interference inside a computer ... (2.5 × 10 −11 error/ ... generating no additional delay to memory accesses as long as no errors are detected.
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 ...
