What process reorganizes data to improve file access speed and efficiency on a computer?

• A. Defragmentation
• B. Compression
• C. Segmentation
• D. Encryption

Answer: (A)

Defragmentation is the process that reorganizes the data stored on a computer’s hard drive to improve access speed and efficiency. Over time, as files are created, modified, and deleted, data becomes fragmented – meaning that files are stored non-contiguously across the disk. This fragmentation can slow down file access because the read/write head of the hard drive must move to different locations to gather pieces of a file. Through defragmentation, the file system rearranges the scattered pieces of data, placing them closer together or consolidating them in contiguous blocks. This leads to quicker read and write operations since the disk's read/write head can access the data more efficiently. As a result, users often notice an improvement in system performance and reduced loading times for applications and files. In contrast, compression reduces the size of files to save space, segmentation refers to dividing data into segments for management purposes, and encryption is the process of securing information by converting it into a code to prevent unauthorized access. While each of these processes serves a specific purpose in data management and security, none directly enhance the speed and efficiency of file access like defragmentation does.
