Answer:
![L=56.2](https://tex.z-dn.net/?f=L%3D56.2)
Explanation:
We need to use two theoretical formulas: Shannon Capacity and Nyquist Bit Rate.
From Shannon:
![C=B*log_2(SNR+1)](https://tex.z-dn.net/?f=C%3DB%2Alog_2%28SNR%2B1%29)
From Nyquist:
![C=2B*log_2(L)](https://tex.z-dn.net/?f=C%3D2B%2Alog_2%28L%29)
Where:
![C= Channel\hspace{3}capacity\\B=Bandwidth\hspace{3} of\hspace{3} the\hspace{3} channel\\SNR=Signal\hspace{3}to\hspace{3}noise\hspace{3}ratio\\L=Number\hspace{3}of\hspace{3}signal\hspace{3}levels\hspace{3}used\hspace{3}to\hspace{3}represent\hspace{3}data](https://tex.z-dn.net/?f=C%3D%20Channel%5Chspace%7B3%7Dcapacity%5C%5CB%3DBandwidth%5Chspace%7B3%7D%20of%5Chspace%7B3%7D%20the%5Chspace%7B3%7D%20channel%5C%5CSNR%3DSignal%5Chspace%7B3%7Dto%5Chspace%7B3%7Dnoise%5Chspace%7B3%7Dratio%5C%5CL%3DNumber%5Chspace%7B3%7Dof%5Chspace%7B3%7Dsignal%5Chspace%7B3%7Dlevels%5Chspace%7B3%7Dused%5Chspace%7B3%7Dto%5Chspace%7B3%7Drepresent%5Chspace%7B3%7Ddata)
Using the data provided by the problem and the equations above, let's find the signal levels we need. Using the Shannon equation:
![C=B*log_2(SNR+1)](https://tex.z-dn.net/?f=C%3DB%2Alog_2%28SNR%2B1%29)
Where:
![B=3000Hz\\SNR=3162](https://tex.z-dn.net/?f=B%3D3000Hz%5C%5CSNR%3D3162)
![C=3000*log_2(3162+1)\\\\C=3000*log_2(3163)\\\\C=34881.23352\hspace{3}bps](https://tex.z-dn.net/?f=C%3D3000%2Alog_2%283162%2B1%29%5C%5C%5C%5CC%3D3000%2Alog_2%283163%29%5C%5C%5C%5CC%3D34881.23352%5Chspace%7B3%7Dbps)
Now, using Nyquist equation:
![C=2B*log_2(L)](https://tex.z-dn.net/?f=C%3D2B%2Alog_2%28L%29)
Where:
![C=34881.23352\hspace{3}bps\\B=3000Hz](https://tex.z-dn.net/?f=C%3D34881.23352%5Chspace%7B3%7Dbps%5C%5CB%3D3000Hz)
![34881.23352=2*3000*log_2(L)\\\\34881.23352=6000*log_2(L)](https://tex.z-dn.net/?f=34881.23352%3D2%2A3000%2Alog_2%28L%29%5C%5C%5C%5C34881.23352%3D6000%2Alog_2%28L%29)
Solving for
:
![\frac{34881.23352}{6000} =log_2(L)\\\\5.81353892=log_2(L)\\\\2^{5.81353892} =2^{log_2(L)}\\ \\56.24055476=L\\\\L\approx56.2](https://tex.z-dn.net/?f=%5Cfrac%7B34881.23352%7D%7B6000%7D%20%3Dlog_2%28L%29%5C%5C%5C%5C5.81353892%3Dlog_2%28L%29%5C%5C%5C%5C2%5E%7B5.81353892%7D%20%3D2%5E%7Blog_2%28L%29%7D%5C%5C%20%5C%5C56.24055476%3DL%5C%5C%5C%5CL%5Capprox56.2)
Therefore, we need approximately 56.2 signal levels.
In supernetting multiple ip addresses referring to a block of cidr addresses can be identified with a single mask.
What is CIDR ?
When a customer requests a fixed number of IP addresses, a group of IP addresses known as Classless Inter-Domain Routing (CIDR) is given to them.
As opposed to classful addressing, CIDR only allots the number of IP addresses that the customer requests, so there is no IP address waste.
Hence, In supernetting multiple ip addresses referring to a block of cidr addresses can be identified with a single mask.
You can learn more about CIDR from the given link:

Answer:
The answer is "Browser to makes the HTML code available ".
Explanation:
URL stands for Uniform Resource Locator which specifies the location of a website in the network of the computer.
- It is the internet address of a resource on the Internet that indicates the protocol used to access this resource.
- The last step in the URL search the HTML code that is made by a visual Web page and by the user's web browser.
