Snooping

• In the context of cybersecurity, "snooping" refers to unauthorized access to another person's or company's data.
• It involves observing, monitoring, or checking someone's data or activity, typically in a secretive or covert manner.
• Snooping can be performed in various ways, including eavesdropping on network traffic, accessing someone else's computer or files without permission, or using spyware to collect information.

The correct answer is option 2.

• The key used to open the CMOS (Complementary Metal-Oxide-Semiconductor) setup utility, also known as the BIOS (Basic Input/Output System) setup, typically varies by motherboard manufacturer.
• However, among the options provided, the "Del" (Delete) key is often used. So, the correct answer would be: Del

Additional Information

Alt: The Alt key, short for "alternate," is typically used in combination with other keys for various functions.

• For example, Alt+F4 is a common keyboard shortcut to close the currently active program on many operating systems.
• In the context of system startup, the Alt key is not typically used on its own to access the BIOS.

Enter: The Enter key is used extensively throughout computing to confirm selections, submit forms, create new lines in text, etc.

• However, on its own, it's generally not used to access the BIOS during system startup.
• Some systems may require you to press Enter to confirm a selection after you've entered the BIOS using a different key, like Del or F2.

Tab: The Tab key is often used to switch focus between different elements in a user interface, such as moving between form fields in a web browser.

• In some BIOS setups, you might use Tab to switch between different sections or fields.
• However, similar to the Enter key, it's not typically used on its own to access the BIOS during system startup.

The correct answer is option 4.

The idea of "cloud computing" involves taking physical resources, such as server storage or processing power, and making them available as a: Virtual resource.

• Virtual resources are not tied to a specific, physical location or hardware and can be scaled up or down depending on user needs.
• This makes cloud computing flexible and efficient, as users only pay for what they use, and resources can be accessed from anywhere with an internet connection.

The correct answer is option 3.

The Melissa virus was primarily spread through: Microsoft Word

• Melissa was a macro virus that was spread via email attachments containing infected Microsoft Word documents.
• When the document was opened, the virus would automatically send itself to the first 50 contacts in the user's address book, leading to a rapid spread of the virus.
• This occurred in 1999, making Melissa one of the first significant email-borne viruses.

The correct answer is option 4.

• Crackers are malicious hackers who break into secure systems with the aim of stealing or damaging information. They are also known as Black Hats.
• A rapid audit of your network machines for flaws, exploits, and information enumerations can be performed using the simple-to-use, intuitive computer network security scanner known as Infiltrator.

The correct answer is option 4.

Key Points 

The full form of the CPU is Central Processing Unit. CPU is the main processing unit of the computer. The CPU is the brain of the computer. CPU receives the data from the input devices and processes it. Then produces the desired output. There are three parts of the CPU. These are the memory unit, control unit and ALU.

• Memory Unit: The memory unit of the CPU is used as a storage unit. After processing the data, the processed data is kept in the memory unit. CPU can reuse the data as per the requirement.
• Control Unit: The control unit is the section of the CPU that selects interprets and sees to the execution of program instructions. It controls the input as well as the output.
• ALU: The full form of ALU is Arithmetic Logic Unit.

All kinds of arithmetic and logical operation are performed here.

Thus the correct answer is the control unit.

Additional Information 

Register unit: 

• A processor register (CPU register) is one of a small set of data holding places that are part of the computer processor.
• A register may hold an instruction, a storage address, or any kind of data (such as a bit sequence or individual characters).
• Some instructions specify registers as part of the instruction.

The correct answer is option 1.

Concept:-

The < dl > tag defines the description list, the < dt > tag defines the term (name), and the < dd > tag describe each term.

Key Points 

• An unordered list starts with the < ul > tag.

Each list item starts with the < li > tag.

• An ordered list start with the < ol > tag.

Each list item starts with the < li > tag.

• HTML also supports description lists. A description list is a list of terms, with a description of each term.

Additional Information Numbered-list:- A list whose items are numbered, with various styles including Arabic numerals and Roman numerals.

The correct answer  is option 2.

"It is a pointing device."

• Both a light pen and a touchscreen are considered pointing devices.
• They allow users to interact with the computer by positioning the cursor. So this isn't a distinguishing advantage.

"It has more positional accuracy."

• This is typically the key advantage of a light pen over a touchscreen.
• Light pens can provide more precision because they can detect the position of the pen tip very accurately.
• This makes light pens useful for detailed work such as graphic design or drafting.

"It is a mechanical pointing device."

• Both light pens and touchscreens are types of mechanical pointing devices.
• They translate physical movement into input that the computer can understand.
• So this isn't a distinguishing advantage.

"It is based on touching a surface pointing device."

• Both light pens and touchscreens require contact with the surface to function.
• The light pen needs to be in proximity to the screen to detect the light emitted by the screen, while a touchscreen responds to the presence of a finger or stylus.
• So this isn't a distinguishing advantage.

The correct answer of above Question is option 2. Crashing

"Hardware Troubles":

• Frequent restarts could potentially be linked to hardware issues, but they don't directly imply a virus infection.
• Problems like overheating, faulty RAM, or a failing power supply can cause this symptom.

"Crashing":

• This is usually the right answer.
• If a virus causes system instability leading to frequent restarts, it could be said that the system is "crashing."
• However, frequent crashes can also be due to software bugs or hardware issues, not just viruses.

"Slow performance":

• While a virus can slow down a computer's performance due to the usage of system resources,
• it does not directly imply that the computer would restart every few minutes.

"Extra files":

• Viruses often create additional files, but these files don't necessarily cause the computer to restart frequently.
• This symptom would more likely result in unexplained disk space usage.

Device Manager → right click on USB Root Hub → Enable Device

• In the context of the question, it's plausible that the USB Root Hub or the specific USB port could have been inadvertently disabled, in which case enabling it would allow the pen drive to be deducted.
• This option assumes that the device has been disabled in the settings, and by re-enabling it, the pen drive would be deducted.
• However, it's important to note that the solution can vary depending on the specific situation.
• If the device isn't disabled, for example, this solution wouldn't work, and one of the other solutions might be necessary.
• It's always best to consider all potential causes and solutions when troubleshooting technical issues.
