In the first step of the boot process, the start-up BIOS does what?
- A.
Runs the POST
- B.
Searches for the OS
- C.
Loads applications
- D.
Loads the OS
Correct Answer
A. Runs the POSTExplanation
The start-up BIOS runs the POST (Power-On Self Test) in the first step of the boot process. The POST is a diagnostic test that checks the hardware components of the computer to ensure they are functioning properly. It verifies the integrity of the CPU, memory, storage devices, and other essential components. By running the POST, the BIOS can identify any potential hardware issues before proceeding with the boot process.Rate this question:

During the second step of the boot process, the start-up BIOS does what?
- A.
Assigns system resources
- B.
Runs the POST
- C.
Searches for and loads an OS
- D.
Loads startup applications
Correct Answer
C. Searches for and loads an OSExplanation
During the second step of the boot process, the start-up BIOS searches for and loads an operating system (OS). This is a crucial step as the OS is responsible for managing the computer's hardware and software resources and allows the user to interact with the computer. The BIOS scans the system to locate the OS files and then loads them into the computer's memory, enabling the OS to take control and continue the boot process.Rate this question:

Configuration information stored in ________________ tells the start-up BIOS where to look for the OS.
- A.
BIOS
- B.
CMOS RAM
- C.
RAM
- D.
Hard drive
Correct Answer
B. CMOS RAMExplanation
Configuration information is stored in CMOS RAM (Complementary Metal-Oxide-Semiconductor Random Access Memory). This information includes settings such as the date, time, and hardware configuration of the computer. During the startup process, the BIOS (Basic Input/Output System) accesses the CMOS RAM to retrieve this information and determine where to look for the operating system (OS) on the computer, such as the hard drive. Therefore, CMOS RAM plays a crucial role in directing the BIOS to the correct location for the OS.Rate this question:
-
- 19.
During the third step in the boot process, the OS does what?
- A.
Configures the system and completes its own loading
- B.
Loads all needed applications
- C.
Waits on the start-up BIOS to check configuration information
- D.
Waits for the user to execute an application
Correct Answer
A. Configures the system and completes its own loadingExplanation
During the third step in the boot process, the OS configures the system and completes its own loading. This means that the operating system sets up the necessary settings and configurations for the hardware and software components of the system to work together. It also finishes loading all the necessary files and processes required for the operating system to run smoothly. This step is crucial for the operating system to be fully functional and ready for the user to interact with.Rate this question:

Correct Answer
B. Application software is loaded and executedExplanation
During the fourth step of the boot process, application software is loaded and executed. This means that after the startup BIOS has controlled the loading, the computer proceeds to load and run the application software that is installed on the system. This step is crucial as it allows the user to interact with the computer and utilize various programs and applications.Rate this question:

If your computer will not boot properly and you hear beeps, what should you do?
- A.
Throw in the towel and chuck the computer
- B.
Consult the motherboard manual or website
- C.
Get ear plugs
- D.
Check the cable between the monitor and tower
Correct Answer
B. Consult the motherboard manual or websiteExplanation
If your computer will not boot properly and you hear beeps, the best course of action would be to consult the motherboard manual or website. Beeps during startup are often a sign of hardware issues, and the motherboard manual or website can provide valuable information about what each beep pattern means. This can help identify the specific hardware component that is causing the problem, allowing you to troubleshoot and resolve the issue effectively. Simply throwing in the towel or checking the monitor cable would not address the underlying cause of the problem. Ear plugs would also not be a solution as they would not fix the computer's booting issue.Rate this question:
