[阅读理解]The TCP protocolis a (71) layer protocol. Each connection connects two TCPs that may be just one physical network apart or located on opposite sides ofthe globe. In other words, each connection creates a (72) witha length that may be totally different from another path created by another connection. This means that TCP cannot use the same retransmission time for all connections. Selecting afixed retransnussion time for all connections can result in serious consequences. Ifthe retransmission time does not allow enough time for a (73) to reach the destination and an acknowledgment to reach the source, it can result in retransmission of segments that are still on the way. Conversely, if the retransnussion time is longer than necessary for a short path, it may result in delay for the application programs.Even for one single connection, the retransmission time should not be fixed.A connection may be able to send segments and receive (74)faster during nontraffic period than during congested periods. TCP uses the dynamic retransmission time,a transmission time is different for each connection and which may be changed during the same connection. Retransmission time can be made(75) by basing it on the round-trip time (RTT). Several formulas are used for this purpose.(71) A.physicalB.networkC.transportD.application(72) A.pathB.windowC.responseD.process(73) A.processB.segmentC.programD.user(74) A.connectionsB.requestsC.acknowledgmentsD.datagrams(75) A.longB.shortC.fixedD.dynamic

[阅读理解]阅读以下说明和C语言函数,将应填入(n)处.(说明)已知1900年1月1日是星期一,下面的函数count_5_13(int year)用于计算给定的年份year中有几个“黑色星期五”.“黑色星期五”指既是13日又是星期五的日期.函数count_5_13(int year)首先算出年份year的1月13日是星期几,然后依次计算每个月的13日是星期几,若是星期五,则计数.程序中使用了函数isLeapYear(int year),其功能是判断给定年份是否为闰年,返回值为1(或0)表示year是(或不是)闰年.(C语言函数)int count_5_13(int year){int date; /*date为0表示星期日,为1~6分别表示星期一至星期六*/long days=0; /*days记录天数*/int m,y,c=0; /*c用于表示黑色星期五的个数*/if (year<1900) return-1;/*计算从1900年1月1日起至给定年份year的1月13日间隔的天数*/days=12;for (y= 1900; y < year; y++) {days +=365;if (isLeapYear(y))(1);}date=((days%7) +1) %7; /*算出给定年份year的1月13日是星期几*/c=((2)) ?1:0;for(m=1;(3);m++) {switch (m) {case 1:case 3: case 5: case 7:case 8:case 10:case 12:days=31; break;case 4: case 6: case 9: case 11:days=30; break;case 2:days=28;if((4)) days=29;break;}/*end of switch*/date=((days%7)+ (5) )%7;if (date==5) c++;} /*end of for*/return c;}
