Its a phrase from at least the early 20th century referring to the unimaginable act of lifting yourself off the ground by pulling on your bootstraps. This technique involves a relatively simple procedure but repeated so many times that it is heavily dependent upon computer calculations.
Bootstrapping is a statistical procedure that resamples a single dataset to create many simulated samples.
Bootstrapping meaning in computer. The phrase bootstrapping in computing comes from the old phrase pull yourself up by your bootstraps. Bootstrapping is a statistical technique that falls under the broader heading of resampling. Bootstraps refer to boots and straps referring to the laces.
This process allows you to calculate standard errors construct confidence intervals and perform hypothesis testing for numerous types of sample statistics. It describes the creation of complex software programs in successive and interdependent stages. Historically bootstrapping also refers to an early technique for computer program development on new hardware.
A bootstrap program is the first code that is executed when the computer system is started. Similarly in the computing world bootstrapping describes a process that automatically loads and executes commands. A figure that demonstrates the use of the bootstrap program is as follows.
The word bootstrapping has come to be used for a variety of other self starting processes. The most fundamental form of bootstrapping is the startup process that takes place when you start up a computer. During the startup process diagnostic tests are performed such as the power on self test post that set or check configurations for devices and implement routine testing for the connection of peripherals hardware and external memory devices.
In fact the term boot as in booting up a computer comes from the word bootstrap. The entire operating system depends on the bootstrap program to work correctly as it loads the operating system. The technique described in this paragraph has been replaced by the use of a cross compiler executed by a pre existing computer.
Bootstrapping provides a method other than confidence intervals to estimate a population parameter. Bootstrapping is the process of loading a set of instructions when a computer is first turned on or booted.
