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)
The quotient is further expressed as the number of times the divisor divides into the dividend, e.g., 3 divides 2 times into 6. A quotient can also refer to the integer part of the result of dividing two integers in Euclidean division. For example, the quotient of 13 divided by 5 would be 2 while the remainder would be 3.
