Bomb

 

(1) An archaic name for an artillery projectile. In smoothbore artillery the term “bomb” or “grenade” refers to a projectile consisting of a spherical, hollow, castiron body, a black powder charge, and a wooden tube with a compressed powder compound. The bomb charge would explode after the time train was ignited. From the 19th century in Russian artillery, projectiles with a mass of more than 1 pood (16 kg) were called bombs. This term was kept for high explosive shells in rifled artillery of calibers of 122 mm and higher. In the beginning of the 1930’s the term “bomb” was dropped from artillery terminology.

(2) Aerial bombs, one of the types of aviation ammunition.

(3) A projectile for destroying submarines underwater.

What does it mean when you dream about a bomb?

A bomb is quite an attention-getter if it goes off in a dream. Perhaps a situation is becoming too explosive and the dreamer needs to tread carefully to avoid “land mines.” Alternatively, perhaps the dreamer is so tightly wound because of some situation that he or she feels ready to explode.

bomb

[bäm]
(computer science)
(geology)
Any large (greater than 64 millimeters) pyroclast ejected while viscous.
(ordnance)
An explosive or other lethal agent, together with its container or holder, which is planted or thrown by hand, dropped from an aircraft, or projected by some other slow-speed device (such as a mortar) and used to destroy, damage, injure, or kill.

bomb

bomb
Laser-guided bomb.
bomb
A conventional free-fall bomb.
An explosive or other lethal agent together with its container or holder, which is dropped from an aircraft and used to destroy, damage, kill, or injure. The bombs can be high-explosive, armorpiercing, semi-armor piercing, runway denial, incendiary, or any such combinations. Also, similar objects in appearance, effect, and operation, such as a leaflet bomb, smoke bomb, photoflash bomb, or practice bomb.

bomb

(software)
General synonym for crash except that it is not used as a noun. Especially used of software or OS failures. "Don't run Empire with less than 32K stack, it'll bomb".

bomb

(operating system)
Atari ST and Macintosh equivalents of a Unix "panic" or Amiga guru, in which icons of little black-powder bombs or mushroom clouds are displayed, indicating that the system has died. On the Macintosh, this may be accompanied by a decimal (or occasionally hexadecimal) number indicating what went wrong, similar to the Amiga guru meditation number. MS-DOS computers tend to lock up in this situation.

bomb

(software)
A piece of code embedded in a program that remains dormant until it is triggered. Logic bombs are triggered by an event whereas time bombs are triggered either after a set amount of time has elapsed, or when a specific date is reached.

abend

(ABnormal END) Pronounced "ab-end." An abend is an unexpected termination that causes the computer, smartphone or tablet to stop responding. The abend occurs either when the processor is presented with instructions or data it cannot recognize, or a program tries to address memory beyond a defined boundary. Abends are generally the result of erroneous software logic in the application or operating system (see anomaly).

Crash, Freeze, Lock Up and Hang
A "crash" occurs when the computer issues a "fault" and deliberately halts that line of execution. The terms "freeze," "lock up" or "hang" may refer to software that is actually still running but has erroneously wound up in an endless, internal loop that renders the program useless. In practice, the terms "crash," "freeze," "lock up" and "hang" are used synonymously. See infinite loop.

Bad Hardware Can Look Like Bad Software
A serious hardware failure will stop a computer-based device that has no redundant components. For example, a short circuit on the motherboard will halt the operation; however, a failing memory cell can cause an instruction to point to an erroneous location, making it look like a software failure.

It Depends on the OS
If the abend occurs due to a bug in an application and the operating system is not resilient, the computer locks up and has to be rebooted. Modern operating systems attempt to halt only the offending application and allow the remaining applications to continue. As operating systems evolve through the years, they become more bug-free themselves and more tolerant of application bugs. However, all operating systems are not 100% foolproof, and bad applications do cause operating systems to crash; a major motivation for virtualizing computers (see virtualization and virtual machine).

A Miracle It All Works
If you consider what goes on inside a computer, you might wonder why it does not crash more often. An ordinary home computer can easily have 64 billion memory (RAM) cells. Every second, millions of them switch their status between charged and uncharged (1 to 0; 0 to 1). If only one cell fails, it can cause an instruction to be invalid, and an abend can occur. See head crash, GPF, active area and transistor concept.



Abending
The green blocks are machine instructions executed by the CPU one after the other until a branch (jump) instruction breaks the sequence and points to an instruction elsewhere in the program. Abending (crashing, hanging, etc.) occurs when the program erroneously points outside of its address space, typically due to bad logic.

logic bomb

A program routine that destroys data when certain conditions are met; for example, it may reformat the hard disk or insert random bits into data files on a certain date or if a particular employee record is missing from the employee database. Many viruses are logic bombs because they deliver their payload after a specific latency or when a trigger event occurs. See virus, latency and payload.

Explosive weapons might affect a wide area because of the large destruction radius of the munition used, the inaccuracy of the delivery system and/or the delivery of multiple munitions over a wide area.
He continues that in their exchanges, representatives realized that the involvement of African States and civil society could play a pivotal role in enhancing the protection of civilians from harm caused by explosive weapons in a time when armed conflicts are increasingly fought in populated centers.
He said: "The nature of explosive weapons is that they obliterate, so it's hard, forensically, to establish after the event if someone was a civilian or armed combatant."
(14) In June 2016, the ICRC published a fact sheet calling on signatories to the conventions and parties to armed conflicts to avoid using explosive weapons that have a wide impact area in densely populated areas due to the significant likelihood of indiscriminate effects.
Beirut: The lives of more than five million Syrians, including two million children, are at risk from explosive weapons used in the conflict, a non-governmental organisation said on Tuesday.
We call on the Syrian Government to refrain from using explosive weapons in populated areas, including airborne weapons, whose indiscriminate effects expose civilians to imminent danger and suffering.UNRWA is closely monitoring reports of civilian fatalities and casualties, said the UNRWA in a statement.
He added that the operation also resulted in the seizure of explosive belts and explosive weapons. / End
A0s, or "ordies" for short, may be best known for loading explosive weapons on the Navy's most advanced aircraft, but they do much more than that.
But more progress is needed, and new frontiers for action have emerged, most notably in Syria and Mali, where the devastating humanitarian impact of the use of explosive weapons in populated areas is growing.
CHAMP, which renders electronic targets useless, is a non-kinetic alternative to traditional explosive weapons that use the energy of motion to defeat a target.
Coffman realized the weapon could affect other parked aircraft and coordinated additional evacuation of adjacent flight line maintainers due to the potential of propagation to highly explosive weapons. As a result, he initiated a 2,500 clear zone, thus securing the safety of personnel from three different units.
