Question:
‘DOS’ floppy disk does not have:
ABoot record
BFile allocation table
CRoot directory
DVirtual memory
Answer:
D. Virtual memory
Explanation:
A DOS floppy disk typically contains:
1. Boot record (or boot sector): Initializes the operating system.
2. File allocation table (FAT): Manages file locations and storage.
3. Root directory: Stores file and directory information.
Virtual memory, however, is not stored on a floppy disk. Virtual memory is:
- A combination of physical RAM and hard drive space.
- Used to temporarily store data when physical RAM is full.
- Managed by the operating system.
DOS floppy disks were widely used in the 1980s and 1990s for data storage and transfer.
Other components you might find on a DOS floppy disk include:
- System files (e.g., IO.SYS, MSDOS.SYS)
- Directory entries
- File data
But virtual memory is not stored on the floppy disk itself.
