subnets will need to occupy 1 bits of the original host identity bit. At this point the network number bit becomes 22 bits and the host label becomes 7 bits. Similarly borrowing 2 host bits can divide a class C network into 4 subnets ... How did the computer know if the network was divided into subnets? This can be se

this connection is called a socket.Establish a network communication connection with at least a pair of port numbers (sockets). Socket is the nature of the programming Interface (API), TCP/IP encapsulation, TCP/IP also to provide the interface for programmers to do network development, this is the socket programming interface; HTTP is a sedan that provides a specific form of encapsulation or display data;

Starting with JDK1.4, Java provides a NetworkInterface class. This class can get information about all the physical network interfaces of the machine and the logical network interfaces that the virtual machines and other software use to create the physical network interface

these matrices, and the θ superscript (j) becomes a wave matrix that controls the action from the first layer to the second or second to the third layer. The first hidden unit calculates its value in this way: A (2) 1 equals the S function or S-excitation function, also called the logical excitation function, which acts on the linear combination of this input. The second hidden unit equals the value of the S function on this linear combination. The parameter matrix controls the mapping from thr
