Threat (computer)

In computer security a threat is a possible danger that might exploit a vulnerability to breach security and thus cause possible harm.

A threat can be either "intentional" (i.e., intelligent; e.g., an individual cracker or a criminal organization) or "accidental" (e.g., the possibility of a computer malfunctioning, or the possibility of a natural disaster such as an earthquake, a fire, or a tornado) or otherwise a circumstance, capability, action, or event.

Computer

A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem.

Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.

Mechanical analog computers started appearing in the first century and were later used in the medieval era for astronomical calculations. In World War II, mechanical analog computers were used for specialized military applications such as calculating torpedo aiming. During this time the first electronic digital computers were developed. Originally they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).

Computer (disambiguation)

A computer is a program machine that receives input, stores and manipulates data, and provides output in a useful format.

Computer may also refer to:

Human computer

The term "computer", in use from the early 17th century (the first known written reference dates from 1613), meant "one who computes": a person performing mathematical calculations, before electronic computers became commercially available. "The human computer is supposed to be following fixed rules; he has no authority to deviate from them in any detail." (Turing, 1950) Teams of people were frequently used to undertake long and often tedious calculations; the work was divided so that this could be done in parallel.

The first time the term "Computer" appeared in The New York Times was February 3, 1853; an obituary stated:

Since the end of the 20th century, the term "human computer" has also been applied to individuals with prodigious powers of mental arithmetic, also known as mental calculators.

Origins in astronomy

The approach was taken for astronomical and other complex calculations. Perhaps the first example of organized human computing was by the Frenchman Alexis Claude Clairaut (1713–1765), when he divided the computation to determine timing of the return of Halley's Comet with two colleagues, Joseph Lalande and Nicole-Reine Lepaute.

Threat

A threat is a communicated intent to inflict harm or loss on another person. A threat is considered an act of coercion. Threats (intimidation) are widely observed in animal behavior, particularly in a ritualized form, chiefly in order to avoid the unnecessary physical violence that can lead to physical damage or death of both conflicting parties.

Some of the more common types of threats forbidden by law are those made with an intent to obtain a monetary advantage or to compel a person to act against his or her will. In all US states, it is an offense to threaten to (1) use a deadly weapon on another person; (2) injure another's person or property; or (3) injure another's reputation.

Brazil

In Brazil, the crime of threatening someone, defined as a threat to cause unjust and grave harm, is punishable by a fine or three months to one year in prison, as described in the Brazilian Penal Code, article 147. Brazilian jurisprudence does not treat as a crime a threat that was proffered in a heated discussion.

Threat (film)

Threat (2006) is an independent film about a straightedge "hardcore kid" and a hip hop revolutionary whose friendship is doomed by the intolerance of their respective street tribes. It is an ensemble film of kids living in New York City in the aftermath of 9-11, each of them suffering from a sense of doom brought on by dealing with HIV, racism, sexism, class struggle, and general nihilism. The intellectual issues are played out amid an aesthetic of raw ultraviolence that has earned director Matt Pizzolo both accolades and condemnations (such as Film Threat's rave review stating "great art should assail the status quo, and that is what Pizzolo and Nisa’s film has skillfully accomplished" in contrast to Montreal Film Journal's scathing review saying the film "openly glorifies murderous revolt, literally telling the audience to go out and beat up random people, just because"). Unlike past urban dramas, the film does not outright condemn its characters' violent outbursts. Although it does show harsh consequences for acts of violence, numerous critics have pointed out that it is unclear whether or not the film intends to glorify violence and/or class conflict.
