Three Logic Levels are used and they are High, Low, HIgh impedance state. The high and low are normal logic levels & high impedance state is electrical open circuit conditions. Tri-state logic has a third line called enable line.

Sublimation is a process when a solid changes directly into gas instead changing into liquid first. Dry ice is an example of Sublimation process because it doesn't change into liquid CO2 and directly change into gaseous CO2 when heated.

Hence, Dry ice is an example of Sublimation process.

The Project Risk Management Processes include the following:

Risk Management Planning - Deciding how to approach , plan, and execute the risk management activities for a project

Risk Identification - Determining which risks might affect the project and documenting their characteristics.

Qualitative Risk Analysis - Prioritizing risks for subsequent further analysis or action by assessing and combining their probability of occurrence and impact

Quantitative Risk Analysis - Numerically analyzing the effect on overall project objectives of identified risks

Risk Response Planning - Developing options and actions to enhance opportunities , and to reduce threats to project objectives.

Risk Monitoring and Control - Tracking identified risks, monitoring residual risks, identifying new risks, executing risk response plans, and evaluating their effectiveness throughout the project life cycle.
