What can file fragmentation cause in DOS systems?

• A. Slower access speeds
• B. Increased storage capacity
• C. Improved file security
• D. Enhanced multi-user access

Answer: (A)

File fragmentation in DOS systems primarily results in slower access speeds. When files are fragmented, they are stored in non-contiguous sectors on the disk. This means that when the operating system needs to read a fragmented file, it has to access multiple locations on the hard drive rather than reading from a single, continuous block. This process requires more seek time and reading time, as the read/write head has to move to different physical locations on the disk to piece together the complete file. As a result, the overall performance is impacted, leading to longer wait times for file access and retrieval. In contrast, unfragmented files are stored sequentially, allowing for quicker access and improved performance. Understanding this can help users manage file systems more efficiently by regularly defragmenting to maintain optimal access speeds.
