Twisted copper telephone wire, coaxial copper cable, fiber-optical cable, and media for wireless transmission are all physical transmission medium.
A system or material that can mediate the propagation of signals for telecommunications purposes is referred to as a transmission medium. Typically, signals are applied to a wave of some sort that is appropriate for the selected medium.
For instance, data may modulate sound, and while air is a common transmission channel for sounds, solids and liquids can also be used. A useful transmission medium for electromagnetic waves like light and radio waves is vacuum or air.
Although a physical substance is not necessary for the propagation of electromagnetic waves, these waves are typically impacted by the transmission medium they pass through, for example, by absorption, reflection, or refraction at the interfaces between media. Therefore, waves can be transmitted or guided using technical devices.

The correct answer for the question that is being presented above is this one: "monopolistic." Suppose barriers to entry exist in the telecommunications industry. This best describes a monopolistic market. In a <span>monopolistic market, that specific source of service or good, is being handled by a single company.</span>
Answer:
The term <u>absolute</u> distinguishes it from a relative address, which indicates a location specifying a distance from another location. <u>Absolute addresses</u> are also called real addresses and machine addresses.
Explanation:
Sorry, I'm not so good at explaining things.. I hope I kinda gave you an idea on what it is though.
Answer:
string=""
while string not in {"Quit","quit","q"}:
string=input("Enter line to be reversed") #line of text will be entered
if string!="Quit" and string!="quit" and string!="q": #If quit is not entered
print("Reverse of line is : ")
print(string[::-1])
OUTPUT :
Enter line to be reversedThis code is in python language
Reverse of line is :
egaugnal nohtyp ni si edoc sihT
Enter line to be reversedHello world
Reverse of line is :
dlrow olleH
Enter line to be reversedquit
Explanation:In the above program, First a while loop is executed and checked if line of text is not 'quit', 'Quit' or 'q'. If condition is true, then loop is executed and in python any string or list can be traversed from end if step is given -1. Similarly line of text is accessed from the last element. If quit is entered, then the program will be broken out of the loop.
Answer:
D) crypto key generate rsa
Explanation:
In cryptography, the RSA refers to Rivest–Shamir–Adleman. This is an algorithm used for encrypting and decrypting messages in computers thereby ensuring secured transmission of data. In order to generate an RSA key pair, you will use the command crypto key generate rsa while in the global configuration mode. This command has the following syntax:
crypto key generate rsa [general-keys| usage-keys| signature| encryption] [<em>labelkey-label</em>] [exportable] [modulus <em>modulus-size</em>] [storage <em>name of device</em>:][redundancy][on <em>name of device</em>:],
with each parameter having its description
