Answer:Start with the algorithm you are using, and phrase it using words that are easily transcribed into computer instructions.
Indent when you are enclosing instructions within a loop or a conditional clause Avoid words associated with a certain kind of computer language.
Explanation:
Answer:
Following are the program in the Python Programming Language.
#set the infinite while loop
while(True):
#get string input from the user
name=input()
#get integer input from the user
num=int(input())
#set the if statement to break the loop
if(num==0):
break
#otherwise, print the following output
else:
print("Eating {} {} a day keeps the doctor away.".format(num, name))
<u>Output</u>:
oranges
5
Eating 5 oranges a day keeps the doctor away.
apple
0
Explanation:
<u>Following are the description of the program</u>:
- Set the loop that iterates at infinite times and inside the loop.
- Declare two variables which are 'name' that get string type input from the user and 'num' that get integer type input from the user.
- Set the if conditional statement for break the infinite while loop.
- Otherwise, it prints the following output.
Answer:

Explanation:
Physical layer is the lowest layer of the OSI reference model that deals with the setup of physical connection to the network and with transmission and reception of signals.
Full duplex (FDx) is a bidirectional type of communication system where two end nodes send and receive data signals at the same time, and a single carrier is simultaneously used for dual communication.
To send or receive data, the participating nodes in a Full Duplex system do not have to wait for a free carrier/medium. It employs a medium that has at least two internal channels - one for sending and one for receiving.
Based on the above explanations, options A, B and C are valid and are correct ways to accomplish full-duplex (FDX) digital communications on guided medium at the physical layer (OSI Layer 1). There all of them are correct.
