The process of starting the computer and loading operating system programs for execution is known as booting.
Explanation:
Boot is a short form of bootstrap, which is derived from the phrase "pulling oneself up by one's bootstraps". In the context of computers, booting refers to the process of starting up a computer system.
During the booting process, several steps are executed to initialize the computer and prepare it for use. These steps include:
1. Power-on self-test (POST):
- The computer's hardware components are checked to ensure they are functioning properly.
- POST checks the CPU, memory, and other hardware devices for any errors or malfunctions.
2. Boot loader:
- The boot loader is a small program that is responsible for loading the operating system into the computer's memory.
- It is typically stored in the computer's firmware or the Master Boot Record (MBR) of the hard drive.
- The boot loader locates the operating system files and begins the loading process.
3. Loading the operating system:
- The operating system files are loaded from the storage device (e.g., hard drive, solid-state drive) into the computer's memory (RAM).
- This allows the operating system to begin running and controlling the computer's hardware.
4. Initialization:
- Once the operating system is loaded, it goes through a series of initialization processes.
- This includes setting up device drivers, configuring system settings, and preparing the user interface.
5. User login:
- The user is prompted to log in or enter a username and password to access the computer.
- After successful login, the user can start using the computer and running applications.
In conclusion, booting is the process of starting the computer and loading the operating system programs for execution. It involves several steps, including the power-on self-test, boot loader, loading the operating system, initialization, and user login.

Detailed Solution for Computer Awareness Quiz -1 - Question 25
Explanation:
In a disk, data is organized into blocks. Each block of data is written into one or more sectors on the disk. The number of sectors used to store a block of data depends on the size of the block and the sector size of the disk.
Here are the options and their explanations:
- Option A: One sector
- This option states that each block of data is written into only one sector. However, this is not always the case as block sizes can be larger than a single sector.
- Option B: Three sectors
- This option states that each block of data is written into three sectors. However, there is no standard practice of using three sectors to store a block of data.
- Option C: Two sectors
- This option states that each block of data is written into two sectors. While it is possible to use two sectors to store a block of data, it is not a universal practice.
- Option D: Two or more sectors
- This option states that each block of data is written into two or more sectors. This option is the most accurate as it allows for flexibility in the number of sectors used to store a block of data.
- Option E: Either two or three sectors
- This option states that each block of data is written into either two or three sectors. While it is possible to use two or three sectors to store a block of data, it is not a universal practice.
Based on the above explanations, option D (Two or more sectors) is the most accurate answer as it allows for flexibility in the number of sectors used to store a block of data.
