Greater than the bit rate of the combined signal The bandwidth of the medium is less than the bandwidth of a single signal The bit rate of the medium is small. The bandwidth of the smallest signal The bit rate of the medium is greater than that of a single signal. The bit rate on the face of it is a better use of the transmission capacity of the channel than , but for now. The reason why computer networks use more than . Poor practical ability can be used for digital transmission. Losing is not enough. The technology is immature, and the bandwidth can be fully shared, but the channel is used in time-sharing. Divide time into time-division multiplexed frames frame of equal length. Each time-division multiplexed user participating in bandwidth sharing. Occupies a fixed number of time slots in each frame. Obviously in this case the bit rate of the medium is greater than the bit rate of a single signal.

Compared with , it has strong anti-interference ability and can regenerate and shape step by step to avoid the accumulation of interference. Moreover, digital signals are relatively easy to achieve automatic conversion. According to the working principle of and suitable for transmitting analog mobile number list signals suitable for transmitting digital signals. The UEC exam questions are available in the following media access control methods. What can conflict is that options and are both channel division protocols channel division protocols. It is a method of statically dividing the channel phone database, and there will be no conflicts for sure. The full name of Carrier Sense Multiple Access Protocol is that the station is sending data. Listen to the channel before finding that the channel is free. Send again, but there may be conflicts during the sending process. In Ethernet, when the data transmission rate increases, the sending time of the frame will be shortened accordingly.

May affect conflict detection. In order to be able to detect conflicts efficiently a resolution can be used. The options are to reduce the length of the cable medium or to reduce the minimum frame length. Increase the length of the cable medium or increase the minimum frame length Increase the length of the cable medium or decrease the minimum frame length Increase the length of the cable medium. length or increase the shortest frame length. In a network using the protocol, the transmission medium is a complete one. A cable with a transmission rate of is the signal propagation rate in the cable that is furthest if the minimum data frame length is reduced by bits. The distance between the two stations needs to be at least . Increase Increase Decrease Decrease Minimum frame length etc. The number of bits sent during the contention period. Therefore, when the transmission rate increases, the length of the cable medium can be reduced.
