Answer :
Transferring the same file from Host A to Host B using network links L1 and L2, L1 will use more transmission time than L2. This is because L1 has a lower bandwidth than L2, resulting in a slower data transfer rate.
The transmission time of a file depends on the bandwidth of the network link being used. In this case, we have two network links, L1 and L2, with bandwidths of 1.2Mbps and 2.3Mbps respectively. We want to transfer the same file, myData.dat, from Host A to Host B using these links.
To determine which link will use more transmission time, we need to calculate the time it takes for each link to transfer the file. We can use the formula:
Time = File Size / Bandwidth
Assuming the file size is fixed, let's say it is 1MB for simplicity. We can calculate the transmission time for each link.
For L1:
Time for L1 = 1MB / 1.2Mbps = 1 / 1.2 seconds
For L2:
Time for L2 = 1MB / 2.3Mbps = 1 / 2.3 seconds
Comparing the two times, we can see that L1 will use more transmission time than L2. This is because L1 has a lower bandwidth than L2, which means it can transfer data at a slower rate. Therefore, the answer is option a. L1 will use more transmission time.
