A communication channel, and the channel capacity (Communication Channel Channel Capacity) The communication channel (Communication Channel) is a channel of data transmission in the computer network, the channel is divided into physical channel and logical channel. The physical channel refers to the physical channel to transmit data signals, which is composed of the transmission medium and the communication equipment; logical channel refers to the basic physical channel, both sending and receiving data signals through the logical connection realized by intermediate nodes, the logical channel for the transmission of data signal form. The logical channel can be connected, or connectionless. The physical channel can also according to the different transmission medium is divided into wired and wireless channel, can also be classified according to different types of data transmission for digital channel and channel simulation. The channel capacity (Channel Capacity) refers to the maximum channel capacity information transmission for digital channel can be transmitted per unit time with maximum bits (bits bit) numbers, for analog channel by ch
