Answer:
def validateCreditCard(x):
if type(x)==str and len(x) == 8:
print("Valid credit card number")
else:
print("Invalid credit card number")
validateCreditCard("43589795")
Explanation:
Run the code on your text editor(vs code, sublime, pycharm ) you will get your desired response. If your input is not of type string and not up to 8 digit you will get the response "invalid credit card number" but if it is of type string and up to 8 digit you will get "Valid credit card number".
But remember python works with indentation so when you are transferring this code to your text editor it will run properly well.
I defined the code using the conventional pattern "def"
After defining the function you create a brackets (x) to accommodate your argument x and end it with a semi colon.
Then i use "if" statement to make sure only string argument and 8 digit value will be accepted to print a "valid credit card". if your argument does not pass the if statement condition it will print out the else statement condition which is "Invalid credit card number"
Finally, you have to call your function and test various values.

Answer explained below
Explanation:
statistical time division multiplexing (STDM) and frequency-division multiplexing (FDM)
They both STDM and FDM works well for the channels which transmit continuously like telephone, FM radio and TV which continuously transmit signal. Since inactive lines are wasted this makes these venues a good fit for STDM and FDM. which means if the signals are dropped or not received to the receiver than it won't have to send the signals again which is why STDM and FDM are useful in these cases.
In Traditional Computer Communications system, the system have tended to be a lot more 'bursty' with idle periods. Hence if we use the FDM and STDM than the usage patterns of STDM and FDM would waste this idle time. so that is why we tend not to use the FDM and STDM in the general purpose computer network.
Answer:
Whenever you use your mobile phone to make a call, it emits electromagnetic radio waves also known as radio frequency or RF energy. Once the radio waves are emitted, the antenna from the nearest cell phone tower will receive them. The antennas of a cell tower can both transmit and receive signals from mobile phones.
