The advantages of a wireless network are as follows:
It provides mobility to users to access a network.
It is easy to connect.
The initial cost to set up a wireless network is low as compared to that of manual cable
network.Data can be transmitted in different ways by using Cellular Networks, Mobitex, DataTAC,
etc.Data can be shared easily between the wireless devices.

The risk management phase that helps in establishing context and quantifying risks is the risk assessment phase. This phase involves a detailed analysis of the potential risks to determine their magnitude and impact on the organization. It includes identifying vulnerabilities, threats, and the likelihood of their occurrence, which helps in understanding the overall risk exposure of the organization. The risk assessment phase is crucial for prioritizing risks based on their severity and for making informed decisions on how to address them effectively.

OPSEC is a 5-step process that helps in developing protection mechanisms in order to safeguard sensitive information and preserve essential secrecy. The OPSEC process has five steps, which are as follows: 1.Identification of Critical Information: This step includes identifying information vitally needed by an adversary, which focuses the remainder of the OPSEC process on protecting vital information, rather than attempting to protect all classified or sensitive unclassified information. 2.Analysis of Threats: This step includes the research and analysis of intelligence, counterintelligence, and open source information to identify likely adversaries to a planned operation. 3.Analysis of Vulnerabilities: It includes examining each aspect of the planned operation to identify OPSEC indicators that could reveal critical information and then comparing those indicators with the adversary's intelligence collection capabilities identified in the previous action. 4.Assessment of Risk: Firstly, planners analyze the vulnerabilities identified in the previous action and identify possible OPSEC measures for each vulnerability. Secondly, specific OPSEC measures are selected for execution based upon a risk assessment done by the commander and staff. 5.Application of Appropriate OPSEC Measures: The command implements the OPSEC measures selected in the assessment of risk action or, in the case of planned future operations and activities, includes the measures in specific OPSEC plans.

biometric
Explanation:
A biometric device is used for uniquely recognizing humans based upon one or more intrinsic,
physical, or behavioral traits.
Biometrics is used as a form of identity access management and access control. It is also used to
identify individuals in groups that are under surveillance. Biometric characteristics can be divided
into two main classes:
1.Physiological: These devices are related to the shape of the body. These are not limited to the
fingerprint, face recognition, DNA, hand and palm geometry, and iris recognition, which has largely
replaced the retina and odor/scent.
2.Behavioral: These are related to the behavior of a person. They are not limited to the typing
rhythm, gait, and voice.
