Answer:
Time required is 0.007 s
Explanation:
As per the question:
Analog signal to digital bit stream conversion by Host A =64 kbps
Byte packets obtained by Host A = 56 bytes
Rate of transmission = 2 Mbps
Propagation delay = 10 ms = 0.01 s
Now,
Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.
Time taken to generate and convert all the bits into digital signal is given by;
t = 
t = 
(Since, 1 byte = 8 bits)
t = 7 ms = 0.007 s
Time Required for transmission of the packet, t':
Answer:
Digital Ocean (but you need to set it up first)
Explanation:
If you are a student, I would recommend Digital Ocean, as you get £50 free credit as part of the GitHub Student Pack. (I believe you have to pay in a little bit however). There are also other reputable hosting providers, AWS should do the trick. For people just starting out, I would recommend hosting from their own machine. If you don't want to pay ever, and are just using basic HTML/CSS, you can use GitHub Pages as a means to host websites.
DO / AWS will only provide you with a blank Linux box, it would then be up to you to install suitable website hosting software - such as Apache/Nginx ect...
