GCSE Fragmentation Quiz

What is fragmentation in disk storage?

• Fragmentation in disk storage refers to the duplication of files and data on a disk.

• Fragmentation in disk storage refers to the compression of files and data on a disk.

• Fragmentation in disk storage refers to the encryption of files and data on a disk.

• Fragmentation in disk storage refers to scattered and non-contiguous storage of files and data on a disk.

How does fragmentation affect disk performance?

• Fragmentation improves disk performance.

• Fragmentation has no impact on disk performance.

• Fragmentation only affects write speeds.

• Fragmentation causes slower read and write speeds.

What are the causes of fragmentation in disk storage?

• New files may not fit completely into the spaces created by deleting old files, so fragments of the new files get written to non-contiguous sectors.

• A power outage or an operating system crash may cause files to become fragmented across the disk.

• Memory leaks in applications may lead to file corruption on the disk.

• Physical damage to the disk may result in the files being fragmented.

What is defragmentation?

• Process of compressing data on a hard drive to save space.

• Process of deleting unnecessary files on a hard drive to free up storage space.

• Process of encrypting data on a hard drive to enhance security.

• Process of reorganizing data on a hard drive to improve efficiency and performance.

What are the benefits of defragmentation?

• Reduced risk of data loss.

• Improved performance and faster access to data.

• Increased storage capacity.

• Enhanced system security.
