The process of developing a new system will have to follow a strict order of a cycle called the system development cycle.The activities in this system development firstly is planning.In planning it must review project requires.
Analysis is the second process in the system development cycle.Which is it must context pull monary investigation before developing a new system.
Thirdly is design for the nem system.To make a design the team must know that their design acquire hardware and software if necessary.
Lastly is implementation.Implementation process must be develop programs if necessary. Then install the new system to know the system is better with the process of the new system.Then convert the new system to replace the old system.

QUESTION 3 :

The advancement of computing industry and computer networking bring about major threat to mankind especially in the area of information privacy.
