This basic process you need to know, that is, every data will go through the process of data encapsulation and unencapsulation.

The key point is that Pizza is defined as an abstract class, which means that in the OrderPizza method we don't care what type this Pizza is at runtime, in other words, this is decoupling. The coupling between PizzaStore and Pizza is uncoupled.
If an attacker sends a large number of SYN requests with fake source addresses, the server side will consume a lot of resources to handle this semi-connection, and saving traversal will consume a lot of CPU time and memory, not to mention retrying SYN + ACK on IP in this list. TCP is a reliable protocol, and messages will be retransmitted at this time. The default number of retries is 5. The interval time of retries is doubled from 1s to 1s + 2s + 4s + 8s + 16s = 31s respectively. After the fifth time is sent out, it will take 32s to know that the fifth time has timed out, so the total is 31 + 32=63s.

"Exposure compensation is also called EV, which is an abbreviation of Exposure Values and a quantity reflecting the amount of exposure. EV +/-commonly known as exposure compensation, it was originally defined as: when the sensitivity is ISO 100, the aperture coefficient is F1, and the exposure time is 1 second, the exposure is defined as 0, the exposure is reduced by one gear (the shutter time is reduced by half or the aperture is reduced by one gear), and the EV value is increased by 1. Increasing and decreasing exposure compensation depends on adjusting the rocker. The shooting environment is relatively dim and needs to increase brightness. When the flash cannot work, the exposure can be compensated and the exposure can be appropriately increased. "
