the nat firewall places only the internal socket in the translation table. (True or False)
False.
A NAT firewall, or Network Address Translation firewall, places both the internal socket (source IP address and port number) and external socket (translated IP address and port number) in the translation table. This allows the firewall to properly translate incoming and outgoing packets between the internal network and the external network.
A NAT firewall is a type of firewall that allows multiple devices on a private network to share a single public IP address when communicating with devices on the internet. It does this by translating the private IP addresses used by devices on the internal network to a single public IP address that can be used by devices on the internet to communicate with the internal network.
To accomplish this, the NAT firewall maintains a translation table that maps the private IP addresses and port numbers of devices on the internal network to the public IP address and port numbers used by the NAT firewall. When a device on the internal network sends a packet to a device on the internet, the NAT firewall replaces the source IP address and port number in the packet header with its own public IP address and a unique port number from the translation table.
When the response packet is received from the internet, the NAT firewall uses the destination IP address and port number in the packet header to lookup the corresponding private IP address and port number in the translation table and forwards the packet to the appropriate device on the internal network.
In summary, the NAT firewall maintains a translation table that includes both the internal and external sockets to properly translate incoming and outgoing packets between the internal network and the external network.

In the long run, the period after all exit and entry have occurred is called the equilibrium. This is when the market reaches a stable state, with no further entries or exits, and supply meets demand.
In computers, equilibrium can refer to several different concepts. One use of the term is in computer science, where it is used to describe the state of a system when it has reached a stable and balanced state. This can be achieved through the use of algorithms and heuristics to optimize a system, such as load-balancing algorithms that distribute workloads evenly across multiple servers. Another use of the term equilibrium in computers is in game theory, where it is used to describe a state of balance between players in a game. In this context, equilibrium is achieved when no player has an incentive to change their strategy, resulting in a stable and predictable outcome.
