to accept the frame, we can be very close to 1 of the probability that these frames in the transmission process did not produce errors. The above mentioned can be approximated as: "There is no error in the frame accepted by the data link layer of the receiving end".⑥ We do not now require the data link layer to provide a "reliable transmission" service to the network layer;* * The so-called "reliable trans

Success lies in persistence, giving yourself this sentence;Today, we review the numerical conversion methods of the two data types: parseint and parsefloat.Compared to number () method, the two methods of parse are relatively diligent, from left to right, and number is a comprehensive analysis;Can understand so parseint, he compared local tyrants, in the conversion value, from left to right, encountered non

Data structure review notes-heap and heap sorting Review the heap knowledge. Deep understanding Heap sortingAndQuick sorting,Merge SortingThe same is a common sorting method with a time complexity of O (N * logN. Before learning about heap sorting, let's take a look at the binary heap.Binary heap Definition The binary heap is a complete binary tree or an appr

Finally, we decided to move towards software developers on the road to the future and review data structures and algorithms from now on. Arrays have several interesting features. 1. For the array int list [3], the compiler interprets list [I] as a pointer to an integer with the address list + I * sizeof (INT. For int * List and int * list2 [5], both are int-type variables, but the compiler will allocate the
