集线器：同一个冲突域 接入设备越多冲突机率越大 用CSMA/CD技术检测和处理冲突 Purpose: This figure compares hubs in a CSMA/CD environment to a highway with multiple access points. Emphasize: The more entrance points onto the highway, the greater the likelihood for a collision to occur. Likewise, the more end stations on a hub trying to access the line, the more collisions occur.
