Data Compression and Utility Software

What is the primary purpose of utility software?

• To run complex applications like video games.

• To manage hardware components directly.

• To keep the computer safe, running efficiently, and manage files/applications.

• To create new operating systems.

Which of the following is NOT explicitly mentioned as a type of utility software?

• File repair

• Backup

• Word processing

• Defragmentation

What is the main function of file repair software?

• To compress large files for storage.

• To restore corrupted or damaged files to a working state.

• To manage network connections.

• To create new files from scratch.

What are the two main types of backups discussed in the video?

• Cloud backups and local backups.

• Manual backups and automatic backups.

• Full backups and incremental backups.

• Daily backups and weekly backups.

What is the primary purpose of data compression?

• To encrypt files for security.

• To reduce file size for efficient storage and transfer.

• To convert files into a different format for compatibility.

• To repair corrupted files.

Which type of data compression permanently removes some data to reduce file size, often used for images and audio?

• Lossless compression

• Run-length encoding

• Lossy compression

• Defragmentation

Why should solid-state drives (SSDs) generally not be defragmented?

• Defragmentation is only for network drives.

• SSDs have no moving parts, making defragmentation unnecessary and potentially harmful.

• SSDs are too small to benefit from defragmentation.

• Defragmentation can only be performed on older hard disk drives.

What is the primary function of anti-malware software?

• To optimize system performance by cleaning temporary files.

• To protect computers from various types of malicious software like viruses and Trojans.

• To compress large files for easier sharing.

• To reorganize fragmented data on a hard drive.
