Study Notes
Fragmentation of Files
- When old files are deleted and new files are saved, files become fragmented, leading to slower access to files.
- Fragmentation occurs when portions of files are scattered in nonadjacent areas on the hard disk.
How Files are Stored on a New Hard Disk
- When a hard disk is new, the operating system stores files contiguously (next to one another).
File Updates and Fragmentation
- When a file is updated, new data is distributed to unused spaces on the hard disk.
- These spaces may not be contiguous to the older data in the file, leading to fragmentation.
Impact of Fragmentation
- Fragmentation slows down the operating system's ability to read files.
- It takes the operating system longer to read fragmented files.
Defragmentation
- A defragmenter utility program, or "defragger," reorganizes scattered files on the hard disk.
- Defragmentation reduces the degree of fragmentation by reorganizing files into the smallest number of adjoining regions.
- Defragmentation increases the computer's speed.
