一个网络节点数是100,假设网络价值系数为2,根据麦特卡夫定律,该网络价值是( )。
- A.10000
- B.40000
- C.20000
- D.5000
正确答案及解析
正确答案
解析
本题考查电子商务发展的一般规律和现象。
鲍勃·麦特卡夫告诉我们:网络价值同网络用户数量的平方成正比,即N个联结能创造N的2次方效益。网络价值可用公式表示为K*N^2,其中N为节点数,K为网络价值系数。如果将机器联成一个网络,在网络上,每一个人都可以看到所有其他人的内容,100人中的每人都能看到100人的内容,所以效率是K倍的100的2次方,即为2*100^2为20000。故本题选C。
考试涉及的常见电子商务发展的一般规律和现象。
摩尔定律(大约每18个月增长一倍)、吉尔德定律(每六个月增长一倍)、梅特卡夫定律(网络价值同网络用户数量的平方成正比)、达维多定律(不断更新产品)、锁定效应(发生成本转移)、安迪-比尔定律(硬件提高的性能、很快就被软件消耗掉了)、反摩尔定律(18个月卖同样产品,营业额降一半)。
