13 multiple choice 2 points what does defragmenting your hard drive do? it backs up your files to the cloud it deletes viruses it cools down your computer it organizes fragmented files to make your computer run faster 14 multiple choice 2 points how can you free up space on your computer? by updating your antivirus software by deleting unnecessary files and uninstalling unused programs by changing the wallpaper by cleaning the keyboard 15 multiple choice 2 points if you are not hearing any sound, what should you check first? your wi-fi connection the computers volume and mute settings the printer connection if the screen is frozen

Explanation:

• Question 13: Defragmenting a hard drive organizes fragmented files. When files are fragmented (stored in non - contiguous locations on the drive), it takes longer for the computer to access them. By defragmenting, the files are re - arranged into contiguous blocks, which can improve the computer's performance. Backing up to the cloud is a different process (data storage off - site), deleting viruses is done by antivirus software, and cooling down the computer is related to hardware cooling mechanisms (like fans).
• Question 14: Deleting unnecessary files and uninstalling unused programs directly removes data and software from the computer's storage, freeing up space. Updating antivirus software mainly improves security, changing the wallpaper is a cosmetic change (no impact on storage), and cleaning the keyboard is a hardware maintenance task (no impact on storage).
• Question 15: If there is no sound, the first logical check is the computer's volume and mute settings. A Wi - Fi connection is related to network access (not sound), a printer connection is for printing (not sound), and a frozen screen is a separate issue (usually related to software or system performance, not sound output).

Answer:

1. It organizes fragmented files to make your computer run faster
2. By deleting unnecessary files and uninstalling unused programs
3. The computer’s volume and mute settings
