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.　　在20世纪30年代的德州，政府依旧沿用着自19世纪70年代开始制定的对黑人实行种族隔离或种族歧视的法律——黑人被剥夺选举权，并在学校、住区、公共交通、公共场所以及就业、司法、军役、婚姻等各方面，受到残酷的隔离和歧视。马文·托尔森作为一名有知识有头脑的黑人非常希望通过自己的她见秦淼尴尬，晓得她不惯做这个的，连她娘云影也不大做针线，因而并不在意那些。项羽曾经有意便宜英布取江东二郡，之后与尹旭为敌的。
