Shadow IT is a(n) ________ phenomenon.

A) BYOD
B) ERP
C) RFID
D) TPS

Shadow IT refers to information technology (IT) systems deployed by departments other than the central IT department, to work around the limitations of the existing IT resources. BYOD (Bring Your Own Device) is a policy that allows employees to bring personally owned devices (laptops, tablets, smartphones) to their workplace and use these devices to access privileged company information and applications. This policy can lead to Shadow IT when employees use their personal devices and software that are not managed by the IT department, creating security and compliance risks.
