When the input value A changes from low to high, the circuit outputs a short spike of duration (∆t 1 + ∆t 2) − ∆t 2 = ∆t 1. A race condition or race hazard is the condition of an electronics , software , or other system where the system's substantive behavior is dependent on the sequence or timing of other uncontrollable events ...
This behavior is also present in Windows 2.0 and Windows 2.1. Windows 3.0 uses a text-mode screen for displaying important system messages, usually from digital device drivers in 386 Enhanced Mode or other situations where a program could not run. Windows 3.1 changed the color of this screen from black
In Windows 3.1, additional options are available, such as /3, which starts Windows in 386 enhanced mode, and /S, which starts Windows in standard mode [2] A startup sound was first added in Windows 3.0 after installing the Multimedia Extensions (MME), [3] but not enabled by default until Windows 3.1.
Boot is short for bootstrap [1] [2] or bootstrap load and derives from the phrase to pull oneself up by one's bootstraps. [3] [4] The usage calls attention to the requirement that, if most software is loaded onto a computer by other software already running on the computer, some mechanism must exist to load the initial software onto the ...
Undetected data corruption, also known as silent data corruption, results in the most dangerous errors as there is no indication that the data is incorrect. Detected data corruption may be permanent with the loss of data, or may be temporary when some part of the system is able to detect and correct the error; there is no data corruption in the ...
An initramfs-style boot is similar, but not identical to the described initrd boot. At this point, with interrupts enabled, the scheduler can take control of the overall management of the system, to provide pre-emptive multi-tasking, and the init process is left to continue booting the user environment in user space.
On hard disks, the virus moves the original master boot record to cylinder 0, head 0, sector 7. On floppy disks, if the disk is 360 KB, the virus moves the original boot sector to cylinder 0, head 1, sector 3. On other disks, the virus moves the original boot sector to cylinder 0, head 1, sector 14. This is the last directory of the 1.2 MB disks.
A classic example is a watchdog timer. See Fail-safe (computer). A control operation or function that prevents improper system functioning or catastrophic degradation in the event of circuit malfunction or operator error; for example, the failsafe track circuit used to control railway block signals. The fact that a flashing amber is more ...
