A streak plate is used to determine the streak colour of a mineral. You take the mineral and scratch it against the streak plate, and it will create a coloured streak on the plate. The streak is not always the same colour as the mineral itself.

To increases the probability that colonies of the desired organism will be isolated upon subsequent streak-plating and not crowded out by others.
Isolation practices are designed to minimize the transmission of infection in the hospital, using current understanding of the way infections can transmit.

In scientific circles, the streak plate method is considered to be a rapid qualitative isolation method. To be effective, one must reduce the number of organisms in the inoculums by spreading a loop of culture over an agar plate. This ensures that individual cells are properly separated on the surface for the purpose of differentiating various species. The method is as follows: Using a sterile loop, microbes are initially transferred to the plate with one swipe. On the subsequent swipes, the loop is heated in the flame of a Bunsen burner to lessen the population of microbes being transmitted. Streak patterns are also done in via T-streak or by applying the loop to four quadrants of the plate.
Isolation streaking was first introduced by Robert Koch as an improvement on the dilution method of isolation of bacterial cultures. Isolation is achieved by taking a minute sample from within one bacterial colony and putting it in a sterile medium so that only that organism will grow. The assumption here is that a bacterial colony has ways of ensuring that no other bacteria will grow within its colonies, primarily by the use of antibiotic compounds that it produces and secondarily by the fact that it will consume available medium before any other organisms can establish themselves. Contamination of a sample by bacteria other than the one desired can lead to improper identification and poor test results. Good isolation such as that provided by the isolation streak method addresses this concern, is cost-effective, and produces acceptable results.

The purpose of having a virtual address is security through process isolation. A virtual address for each space is private and therefore increases security.
