Question 4 Bluetooth headsets
Blue tooth headsets have both advantages and disadvantages associated with the technology. The first advantage is that there are no wires used thus the limitations associated with distance constraints are minimized if not eliminated. With wireless headsets, handling calls while driving is easy and simplified. It allows hands free phone call reception thus eliminating accidents associated with driving while on a phone call. Bluetooth wireless signals use low power signal unlike wired headsets. Blue tooth headset is universal meaning it can be used in any device that is Bluetooth enabled.
On the other hand, Bluetooth headsets are more expensive compared to their wired counterpart. It can be as much as ten times the cost of the normal traditional headsets. It has a mono output which affects the quality of sound it generates as compared to the traditional wired headsets. Finally, Bluetooth headsets are limited in some way by signal range. The device has to be close to the headset for a quality sound and operation.

The activities must be conducted in sequence, meaning that an activity cannot be started if the previous activity in the sequence has not been completed. Any delays in the sequence may cause the entire project to delay.
Question 9
Social engineering attack on business information technology is when an attacker uses social skills such as human interaction to gather and piece together information that can compromise the security of an organization and its computer system.
