Answer:
1010 0111 1101 1111
Explanation:
A = 10 in decimal = 1010 in binary
7 = 7 in decimal = 0111 in binary
D = 13 in decimal = 1101 in binary
F = 15 in decimal = 1111 in binary
Therefore 0xA7DF = 1010 0111 1101 1111 in binary

Corrective maintenance: It basically refers to the changes made to repair the defects in the implementation and designing of the system. It is usually performed after the failure occur in the equipment. It also increased overall productivity of the system.
Perfective maintenance: It basically improve the performance of the system, efficiency and maintainability. This type of maintenance are initiated by the IT department.
Adaptive maintenance: It involves the implementation changes in the system to increase its functionality. It basically improve its efficiency and increase its capability. It is less urgent than corrective maintenance.
