Let t=0 denote the start of transmission. At t=1 msec, the first frame has been fully transmitted. At t=271 msec, the first frame has fully arrived. At t=272 msec, the frame acknowledging the first one has been fully sent. At t=542 msec, the acknowledementbearing frame has fully arrived. Thus, the cycle is 542 msec. A total of k frames are sent in 542 msec, for an efficiency of k/542. Hence a) k=1, efficiency=1/542=0,18% b) k=7, efficiency=7/542=1,29% c) k=4, efficiency=4/542=0,74%
The result of adding 542 plus 542 is equal to 1084.
The positive integer factors of 542 are: 1, 2, 271, 542
542 542 or 6969
542 + 8 = 550
542 / 7 = 77.42857
The Bulgarians and the Arabs were the 2 main enemies of the byzantine empire.
271 x 2 = 542 542 + 542 = 1,084 = 271 x 4
