E
Correct Answer
C. CExplanation
Class C fire extinguishers are used to extinguish electrical fires. This is because Class C fires involve energized electrical equipment, such as appliances, wiring, circuit breakers, and outlets. Class C extinguishers contain non-conductive agents, such as carbon dioxide or dry chemical powder, which smother the fire and interrupt the electrical current, making them safe to use on electrical fires.Rate this question:

RAM provides tempory data storage for the CPU while the computer is operating. RAM is .............. ................., which means its contents are lost when the computer shuts down.
Correct Answer
Volatile MemoryExplanation
RAM stands for Random Access Memory, which is a type of volatile memory. Volatile memory refers to the temporary storage of data that is lost when the computer is shut down or loses power. RAM is used by the CPU to store data that is actively being used by the computer while it is operating. Since RAM is volatile, its contents are not retained when the computer is turned off, making it necessary to save important data to a non-volatile storage device, such as a hard drive.Rate this question:

What partition is used by the operating system to boot the machine?
- A.
Primary
- B.
Extended
- C.
Active
- D.
Logical
- E.
Slave
Correct Answer
C. ActiveExplanation
The active partition is used by the operating system to boot the machine. The active partition is a primary partition on a disk that contains the boot loader, which is responsible for starting the operating system. When the computer starts up, the BIOS looks for the active partition and loads the boot loader from it. The boot loader then loads the operating system into memory and starts its execution. The other options (Primary, Extended, Logical, and Slave) are not directly related to the boot process of the operating system.Rate this question:

- B.
Information relating to all active devices on a system
- C.
Information about all users who have logged on to a system
- D.
Information relating to the hardware and software
- E.
Information, such as desktop settings and history, related to the current user of a PC
Correct Answer
D. Information relating to the hardware and softwareExplanation
HKEY_LOCAL_MACHINE is a registry key that contains information relating to the hardware and software of a system. It stores configuration settings, device driver information, and other system-related data. This key is used by the operating system and various applications to access and modify system settings and configurations. It is an essential part of the Windows registry and plays a crucial role in system operations and maintenance.Rate this question:

What does (ACPI) stand for and what does it do?
- A.
Advanced Configuration and Power Interface, control's power management features.
- B.
Advanced Control and Power Integration. Control's Hard Drives
- C.
Automated Clock and Processor Instructions. Control's the clock and processor speed
Correct Answer
A. Advanced Configuration and Power Interface, control's power management features.Explanation
ACPI stands for Advanced Configuration and Power Interface. It is a standard developed by Intel, Microsoft, and Toshiba that defines a set of power management and configuration interfaces. ACPI allows the operating system to control the power management features of a computer system, such as turning off or putting devices into low-power states when they are not in use. It also enables features like sleep mode and hibernation. Therefore, the correct answer is "Advanced Configuration and Power Interface, control's power management features."Rate this question:

WEP stands for Wired Equivalent Privacy, True or False
Correct Answer
trueExplanation
WEP stands for Wired Equivalent Privacy, which is a security protocol used to secure wireless networks. It was designed to provide the same level of security as a wired network. However, WEP has been found to have several vulnerabilities, making it relatively easy to crack. Despite its weaknesses, WEP was widely used in the early days of wireless networking. Today, it is considered outdated and insecure, and it is recommended to use more robust security protocols such as WPA or WPA2. Therefore, the statement "WEP stands for Wired Equivalent Privacy" is true.Rate this question:
