What does the process of 'defragmentation' do?

• A. Removes unwanted files from the hard drive
• B. Reorganizes fragmented data on hard drives to improve efficiency
• C. Scans for and removes viruses from the system
• D. Upgrades the hard drive capacity

Answer: (B)

Defragmentation is a process that reorganizes fragmented data on hard drives to improve efficiency. Over time, as files are created, modified, and deleted, data can become scattered or fragmented across the disk. This fragmentation can lead to slower access times because the read/write head of the hard drive has to move to different locations to retrieve a single file. By running a defragmentation process, the operating system rearranges the fragmented pieces of files so that they are stored in contiguous sections of the hard drive. This reorganization helps in reducing the time it takes for the hard drive to read and write data, thereby improving the overall performance and efficiency of the system. The other answer choices relate to different maintenance tasks or functions but do not describe the defragmentation process accurately. For example, removing unwanted files pertains to disk cleanup, scanning for and removing viruses involves cybersecurity practices, and upgrading hard drive capacity deals with hardware enhancements rather than file organization.
