The correct answer is option C, a small initialization program to start up a computer. A bootstrap is a small program that is executed when a computer starts up. It is responsible for loading the operating system and other necessary software into memory, so that the computer can become fully operational.

Explanation:

A bootstrap is a small initialisation program to start up a computer. The term 'bootstrap' comes from the phrase 'pulling oneself up by one's bootstraps', which means to start from scratch and build something up bit by bit. The bootstrap program is stored in ROM or flash memory on the computer's motherboard, and it is the first code that runs when the computer is turned on.

The bootstrap program performs a series of tasks to initialise the computer and prepare it for operation. These tasks include:

1. Power-on self-test (POST): The bootstrap program performs a series of diagnostic tests to check the computer's hardware components, such as the memory, CPU, and input/output devices. If a problem is detected, an error message is displayed.

2. Loading the operating system: Once the POST is complete, the bootstrap program locates and loads the operating system into memory. The operating system is the software that manages the computer's resources and provides a user interface.

3. Configuring system settings: The bootstrap program sets various system settings, such as the date and time, keyboard and mouse settings, and network configuration.

4. Handing off control to the operating system: Once the operating system is loaded and running, the bootstrap program hands off control to it. The operating system takes over and continues the boot process, loading drivers and other system components as needed.

In summary, the bootstrap is a small program that is responsible for starting up a computer and preparing it for operation. Without the bootstrap program, the computer would not be able to load the operating system and run applications.
