TCB (TCP? Transport Control Block is a transport protocol data structure that contains all the information of the connection (in fact, in many operating systems, it is a queue used to process inbound connection requests. The queue holds TCP connection items that are in a half-open state and items that have established a full connection but have not yet been extracted by the application through an accept () call). The amount of memory occupied by a single TCB depends on the implementation of TCP options and other functions used in the connection. Usually a TCB has at least 280 bytes, which in some operating systems has exceeded 1300 bytes. The SYN-RECEIVED state of TCP is used to indicate that the connection is only half open, and the legality of the request is still questioned. An important aspect worth noting here is that the size of TCB allocation space depends on the SYN packets received-before the connection is fully established or the return reachability of the connection initiator is verified.

Javascript neither supports abstract classes nor has the concept of interfaces. Therefore, be very careful when using the state mode. If you forget to implement the buttonWasPressed method for a state subclass when writing a state subclass, an exception will be thrown when the state switches. Because Context always delegates requests to the buttonWasPressed method of the state object. Therefore, let the abstract method of the abstract parent class throw an exception directly, which will be found at least during the program run.
