Active Sampling refers to the process of connecting sample collection media (i.e., thermal desorption tube) to a sampling train consisting of inert tubing and a sample pump operating at a know flow rate. Once activated, the sample pump draws air through the sample media, resulting in a know sample volume. Passive Sampling refers to the process of allowing sample collection media (i.e., thermal desorption tube) to passively diffuse air through the sample media without benefit of 'forced air'. This allows for longer potential sample periods without concern for overloading the sampling media. •

Active monitoring involves sending out probes to actively collect data, while passive monitoring involves collecting data that is already flowing through the network. Active monitoring can be more intrusive and can impact network performance, whereas passive monitoring is typically non-intrusive. Both methods have their own advantages and limitations in terms of the depth of analysis and resource utilization.

What is the difference between active and passive data dictionary?
Active data dictionary is constantly updated and reflects real-time changes within a database or system, while passive data dictionary is static and does not change unless manually updated. Active data dictionary is dynamic and integral to system operations, providing current information about data elements, relationships, and structures. Passive data dictionary is more archival in nature, serving as a reference for historical data definitions and structures.
What is the syllabus in DIT?
The syllabus in DIT typically covers a range of subjects related to information technology, such as programming languages, databases, networking, web development, and software engineering. It may also include courses on topics like cybersecurity, data analysis, and project management. Each module will have specific learning objectives and assessments to gauge understanding of the material.
What is the use of taking passive monitoring when direct monitoring is there in industrial hygiene?
Direct monitoring of contaminants in the air is a long established process of directly measuring contaminants in place. This often requires bulky equipment and is suitable for measuring only one agent or family of agents. Passive monitoring may be direct reading, in which case it is a subset of direct monitoring that usually involves very light and small devices that can be easily worn by an individual Passive monitoring can also be a method for collecting a sample of air to be analyzed in a laboratory with equipment able to assess a broad range of different agents in the same sample. In this case, passive monitoring (more properly called passive sampling) collects the sample without requiring the use of a pump or other active device to draw the air into the sampling medium. All variations of monitoring and sampling methods have advantages and disadvantages. As a result, different methods will be better suited for different situations.

The difference between a passive and an active dividend policy.?
The difference between a passive and an active dividend policy lies in the amount of time between dividend disbursement. In a passive dividend policy, dividends are given when the company decides it is time. With an active dividend policy, dividends are disbursed at regular intervals.

What is the defference between active transpors and passive transport?
The difference between active and passive transport, is that, active transport, requires energy input from the cell, in order to occur, unlike passive, which occurs, without any energy input.
What is the difference between passive voice and compound nominal predicate?
The passive voice applies to a verb and its clause; the compound nominal predicate is the verb and its qualifiers which may be in the active or passive voice.
What is the difference between the passive and active route status as displayed in an eigrp topology table?
In EIGRP, the passive route status in the topology table indicates a route to a network that is not an EIGRP neighbor, while the active route status indicates a route to a network that is being actively queried and computed by the EIGRP router as a potential successor for the routing table.
Difference between active and passive optical component?
Fiber optic couplers can be either active or passive devices. The difference between active and passive couplers is that a passive coupler redistributes the optical signal without optical-to-electrical conversion. Active couplers are electronic devices that split or combine the signal electrically and use fiber optic detectors and sources for input and output.

What is the difference between assertive and passive people?
Assertive people are confident in expressing their opinions, setting boundaries, and standing up for themselves in a respectful manner. Passive people tend to avoid conflict, suppress their feelings, and have difficulty asserting themselves or expressing their needs.
