The API changes should provide both source and binary (71)for programs written to the original API. That is, existing program binaries should continue to operate when run on a system supporting the new API, In addition, existing (72) that are re-compiled and run on a system supporting the new API should continue to operate. Simply put, the API(73) for multicast receivers that specify source filters should not break existing programs, The changes to the API should be as small as possible in order to simplify the task of converting existing (74)receiver applications to use source filters. Applications should be able to detect when the new(75)filter APls are unavailable(e.g., calls fail with the ENOTSUPP error) and react gracefully(e.g., revert to old non-source-filter API or display a meaningful error message to the user). 空白处(71)应选择()
A. capability
B. compatibility
C. labiality
D. reliability
共用题干题采用可变长子网掩码可以把大的网络划分成小的子网,或者把小的网络汇聚成大的超网。假设用户U1有4000台主机,则必须给他分配(35)个C类网络,如果分配给用户U1的超网号为196.25.64.0,则指定给U1的地址掩码为(36);假设给用户U2分配的C类网络号为196.25.16.0~196.25.31.0,则U2的地址掩码应为(37);如果路由器收到一个目标地址为11000100.00011001.01000011.00100001的数据报,则该数据报应送给用户(38)。 空白处(35)应选择()
