Systems tolerate this inefficient algorithm, as it is an essential feature for most software, especially string processing. Unlike bytes, larger units can span two aligned addresses and would thus require more than one fetch on the data bus.
With memory protection, only the program's own address space is readable, and of this, only the stack and the read/write portion of the data segment of a program are writable, while read-only data allocated in the const segment and the code segment are not writable. Thus attempting to read outside of the program's address space, or writing to a ...
Memory corruption occurs in a computer program when the contents of a memory location are modified due to programmatic behavior that exceeds the intention of the original programmer or program/language constructs; this is termed as violation of memory safety. The most likely causes of memory corruption are programming errors (software bugs ...
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.

A software bug is a design defect in computer software. A computer program with many or serious bugs may be described as buggy . The effects of a software bug range from minor (such as a misspelled word in the user interface ) to severe (such as frequent crashing ).
In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits. On some operating systems or individual applications, a crash reporting service will report the crash and any details relating to it (or give the user the option to do so), usually to ...
