Static vs Dynamic Filtering -- Static (constant and unchanging) packet filtering offers security against novice hackers. You can configure the filtering rules when you install a firewall to filter based on source/destination IP addresses. This sets up a static filter. But static packet filtering does not have the intelligence to selectively open and close ports; it can either open all the non-private ports or close them all. If all ports are kept open, an intruder can break in; if all ports are closed, the firewall becomes obtrusive to the users on the network. (To see why ports are opened, see the section on FTP Security, below.) Dynamic filter

BeauA static firewall uses predetermined rules or policies to filter traffic based on factors like IP address or port number, while a dynamic firewall can adapt its rules in real-time based on the behavior of network traffic. Dynamic firewalls are more flexible and can provide better security by allowing for continuous monitoring and response to changing threats.

What is the relationship between dynamic and static pressure in fluid mechanics?
In fluid mechanics, dynamic pressure is the pressure exerted by a fluid in motion, while static pressure is the pressure exerted by a fluid at rest. The relationship between dynamic and static pressure is described by the Bernoulli's equation, which states that the total pressure in a fluid system is the sum of dynamic and static pressure. As the fluid velocity increases, dynamic pressure increases while static pressure decreases, and vice versa.

What is the relationship between static and dynamic pressure in fluid mechanics?
In fluid mechanics, static pressure is the pressure exerted by a fluid at rest, while dynamic pressure is the pressure exerted by a fluid in motion. The relationship between static and dynamic pressure is described by the Bernoulli's principle, which states that the total pressure in a fluid system is constant along a streamline. This means that as the dynamic pressure increases, the static pressure decreases, and vice versa.
What is the Difference between Dynamic pressure and static pressure?
Dynamic pressure is the pressure exerted by a fluid in motion, caused by its velocity, while static pressure is the pressure exerted by a fluid at rest. Dynamic pressure increases with the square of the velocity, whereas static pressure remains constant regardless of velocity.
What is Difference between static and dynamic latch?
A static latch operates by maintaining its output state when the clock is inactive, while a dynamic latch relies on a clock signal to control its operation. Dynamic latches typically require more complex circuitry and consume more power compared to static latches. Static latches are often used in synchronous designs, while dynamic latches are more common in dynamic logic circuits.
