三、计算机网的传输方法为保证把信息从一端成功地传送到另一端,必须根据信息类型、介质特征、拓扑结构以及地理范围等因素选择合适的传输方式,计算机网(特别是局部网),经常采用的是基带方式和宽带方式,表3给出了它们之间的差别.1.基带方武基带方式传输的是未经
Third, the computer network transmission method To ensure the successful transfer of information from one end to the other, we must select the appropriate transmission mode, the computer network (especially local area network) according to the type of information, media characteristics, topological structure and geographical scope and other factors, Often used is the baseband mode and broadband mode, the difference between them is given in Table 3. The baseband side Wu base band mode transmission is not
