有m个进程(P0，P1，…，Pm-1)通过n个缓冲区(B0，B1，…Bn-1)向1个进程(Q)发送数据包，每个数据包大小与缓冲区一样。要求：进程Q接收数据包的次序与发送次序一样。为保证发送进程与接收进程正确地并行工作，需要设置(23)。

Soon,　more　of　the　information　we　receive　via　the　Internet　could　come(71)in　digital　wrappers.

Wrappers　are　made　up(72)software　code　that's　targeted　to　do　specific　things　with　the　data(73)within　them,　such　as　helping　to　define　queries　for　search　engines.　They　also　keep(74)from(75)access　to　that　code.

Developing　reliable　software　on　time　and　within(66)represents　a　difficult　endeavor　for　many　organizations.

Usually　business　solutions　have　three　main　aspects:　people,(67),and　technology.　The　main　reason　for　failing　software　projects　has　little　to　do　with　technology　and　tools,　and　much　to　do　with　lack　of　process(68).　Experience　has　shown　that　introducing　new　technology　and　tools　in　an　immature　or　undisciplined　environment　is　likely　to　increase　the　chaos.　CASE　tools　are　not　enough.　"A　fool　with　a　tool　is　still　a　fool　!"

Structured　method　was　the　first　wave　of　the　software　industry.　This　was　the　beginning　of　transforming　software　development　from　a"(69)industry"　to　mass　production.　Software　process　movement　if　the　second　wave　in　the　software　industry.　The　process　maturity　movement　prepares　the　way　for　the　third　wave　of　the　software　industry　:"software　industrialization".　Software　development　will　become　like　an　assembly　and　manufacturing　process.　A　cfiticalenabling　factor　is　adisciplined　software　engineering　.　process　with　predictable　quality,(70)and　functionality.
