Defragmentation is a process used to reorganize the data on a computer's hard drive. Over time, files can become fragmented, meaning they are stored in non-contiguous spaces. This can slow down the computer's performance because the hard drive has to work harder to access these scattered pieces of data. By defragmenting the drive, the system moves the fragmented files closer together, allowing for quicker access and improved efficiency. Most operating systems, like Windows and macOS, include built-in defragmentation tools. Users can run these tools manually or schedule them to run automatically. Regular defragmentation can help maintain optimal performance, especially for traditional hard disk drives (HDDs), although it is less necessary for solid-state drives (SSDs) due
