Explain how the operating system manages memory using Virtual Memory and Paging when the physical RAM is completely filled with active customer requests, and describe what is meant by 'Disk Thrashing'.

The server administrator configures an automated backup utility. Compare a Full Backup with an Incremental Backup, giving one advantage of each approach for the corporate server.

The server utilizes a traditional magnetic Hard Disk Drive (HDD) for secondary storage. Describe how the File Allocation Table (FAT) tracks fragmented files across non-contiguous disk sectors, and explain how a disk defragmentation utility improves data retrieval speeds.
