6⟩ Explain Floppy Disk Drive?
A Floppy Disk Drive, also called FDD or FD for short, is a computer disk drive that enables a user to save data to removable diskettes. Although 8" disk drives were first made available in 1971, the first real disk drives used were the 5 1/4" floppy disk drives, which were later replaced with the 3 1/2" floppy disk drives.

14⟩ What is the maximum hard drive size for FAT16-based Windows system?
Maximum hard drive size for FAT16-based Windows system iMaximum hard drive size for FAT16-based Windows system is 2 GB. s 2 GB.
Microsoft MS-DOS versions 4.0 and later allow FDISK to partition hard disks up to 4 gigabytes (GB) in size. However, the MS-DOS file allocation table (FAT) file system can support only 2 GB per partition. Because of this fact, a hard disk between 2 and 4 GB in size must be broken down into multiple partitions, each of which does not exceed 2 GB.
15⟩ Explain Which microprocessor accepts the program written for 8086 without any changes?
Intel 8088 is the microprocessor performing same function as 8031 for 8051 micro controller.
