To maintain system efficiency, a system analyst may recommend _____________ software, which organizes and defragments a computer's hard drive.

Correct option is B

A Disk Defragmenter is a software tool designed to optimize the performance of a computer by reorganizing fragmented data on the hard drive. Fragmentation occurs when files are stored in non-contiguous spaces, leading to slower access times. The disk defragmenter improves system efficiency by rearranging these files into contiguous blocks.

Important Key Points:

1. Disk Defragmenter helps improve system performance by optimizing the way files are stored on the hard drive, reducing the time it takes to access and load files.
2. It works by consolidating fragmented files, which are scattered in non-contiguous spaces, into contiguous sections of the disk.
3. This process is particularly useful for traditional hard disk drives (HDDs), though it is not needed for solid-state drives (SSDs).

Knowledge Booster:
• A disk cleanup tool helps remove unnecessary files, like temporary files and system caches, to free up space but does not defragment the drive.
• A backup utility helps in creating copies of important data, which is essential for data protection but not related to improving disk performance.
• Antivirus software is designed to detect and remove malicious software, ensuring system security, but it does not focus on improving disk efficiency.
