LAB 1.5: CREATING A FILE SYSTEM Exercise 1.5.4 Use the web to identify issues that disk fragmentation can cause for computer performance. Will changing your file structure affect the fragmentation of the disk? Can cause the same file to be stored and different sections of the computer causing the computer to take a longer period of time to load the files or program, causing the overall performance to be a lot slower than normal; changing your file structure will change the fragmentation of the disk.
