Hey, I have started these questions off but just wanted to ask if somebody could check it and explain if they are incorrect.
Thanks.

Hi @EM,
Your first step is correct. The file size of one photo, is 41943040 bits. The question asks for the time it takes to transfer 2000 of these photos, so you would have to work out the total size of all 2000 photos, which can be done by multiplying the size of one photo by 2000.
After that, you can work out the time taken, in seconds, to transfer the data by dividing the total data size by the data transfer speed (which should be in bits per second). As the question has not given you the data transfer speed, I would assume you simply have to explain in words how to calculate the time taken.
The table mostly seems correct, except from the range and security of fibre optic cables compared to copper cables. I would suggest doing some further reading on this. There are quite a few interesting articles online detailing the differences and the reasons for them, such as this one.
Hope this helps. Please let me know if you have any further questions.
