Many trojans and backdoors now have remote administration capabilities allowing an individual to control the victim's computer. Many times, a file (often called a client or stub) must be opened on the victim's computer before the hacker can have access to it.
quotient - the ratio of two quantities to be divided. 1  proportion - the quotient obtained when the magnitude of a part is divided by the magnitude of the whole. 2  ratio - the relative magnitudes of two quantities (usually expressed as a quotient)
In mathematics, a limit is the value that a function or sequence approaches as the input or index approaches some value. Limits are essential to calculus (and mathematical analysis in general) and are used to define continuity, derivatives, and integrals. The concept of a limit of a sequence is further generalized to the concept of a limit of a topological net, and is closely related to limit and direct limit in category theory. In formulas, a limit is usually written as. and is read as the limit of f of n as n approaches c equals L .
