An application that reads file segments from non-contiguous sections of a storage device and then writes the files to the same device in such a way that each file segment is contiguous.

• A. defragmentation software
• B. digital data
• C. computer architecture
• D. data bus

Answer: (A)

Reducing fragmentation by reorganizing how data is laid out on the storage device. Fragmentation happens when file pieces end up scattered across non-adjacent sectors. An application that reads those scattered segments and then rewrites them so each file’s data sits in a single, continuous block is performing defragmentation. This makes reading files faster because the disk head can read sequentially rather than jumping around. The other options don’t describe this process: digital data is just data in general, computer architecture is about how a computer’s components are organized, and a data bus is a hardware channel for moving data.
