9 multiple choice 2 points
why should you avoid placing your computer on soft surfaces like a bed or couch?
it can block airflow, leading to overheating
it can cause the screen to crack
it can make the computer slower
it can increase your internet speed

Explanation:

• Question 7: Sound - related issues on a computer often start with basic audio - related settings. The computer's volume and mute settings directly affect sound output. Wi - Fi is for network connectivity, the printer is for outputting physical documents, and a frozen screen is a display - related issue.
• Question 8: Defragmenting a hard drive is a process in computer maintenance. It arranges fragmented files on the hard drive. Cooling down the computer is usually done by the cooling system (fans, heat sinks), deleting viruses is the job of antivirus software, and backing up to the cloud is a separate backup operation.
• Question 9: Soft surfaces like beds or couches can block the air vents of a computer. Computers need proper airflow for cooling. A blocked airflow can cause the internal components to overheat. Cracking the screen is more likely due to physical impact, making the computer slower can have many causes (like software issues, low memory etc.) but not directly from blocking airflow on a soft surface, and increasing internet speed is related to network settings and hardware (router, modem etc.).

Answer:

• Question 7: The computer’s volume and mute settings
• Question 8: It organizes fragmented files to make your computer run faster
• Question 9: It can block airflow, leading to overheating
