Workstations can serve as basic servers in small networks. While they are typically used for individual tasks, they can be configured to act as servers for file sharing, printing, or hosting lightweight applications without needing specialized installation or infrastructure.
Minicomputers (B) are outdated mid-range systems.
Supercomputers (C) are specialized, high-cost systems for massive computations, not typical servers.
"None of the above" (D) is incorrect because workstations can indeed be used as servers.

Probability of detection refers to the likelihood that an intrusion or unauthorized action will be identified by the security system. It is a key performance metric used to evaluate the effectiveness of electronic security components such as sensors and alarms. A high probability of detection means a more reliable system.
A (System validation) is a phase where detection may be measured, but it's not the definition.
B (Officer response) is unrelated to detection probability.
D (Response timing) is part of delay or intervention, not detection.

When an organization employs contract security services, the administrative workload related to hiring, payroll, training, and scheduling shifts to the service provider. This is a significant benefit for companies looking to reduce internal administrative burdens and focus on core operations.
Proprietary (C) systems require the organization to manage all aspects of employment.
Union (A) and Security (B) are unrelated to the comparison of administrative workload between contract and proprietary services.

An Invitation for Bid (IFB) is a procurement method used when requirements are clearly defined and price is the main selection criterion. It typically requires bidders to submit pricing in a specific format so that proposals can be directly compared.
A, B, and C relate more to Requests for Proposals (RFPs), where qualitative evaluation (e.g., technical capability) plays a bigger role.

Arrest refers to the legal act of taking a person into custody. One of the essential legal requirements following an arrest is that the individual must be handed over to law enforcement or judicial authorities without unreasonable delay. This is to protect the constitutional rights of the detainee and avoid unlawful detention.
Detain (B) and Detention (C) refer to temporary restraint without full arrest.
Threatening loss (D) is unrelated.
