Answer:
These systems are commonly used in facilities such as public libraries to ensure equitable use of limited numbers of computers. Bookings may be done over the internet or within the library itself using a separate computer set up as a booking terminal.
Answer:
Option B i.e., Circuit level gateways only enable data to be inserted into a network which is the product of system requests within the network.
Explanation:
In the above question, some details are missing in the question that is options.
Option B is valid because Circuit level gateways are not the transmission inspection, always require information into such a server resulting through system appeal inside the server through maintaining a record for connections that are sent into the server and only enabling information in this is in answer to such queries.
Other options are incorrect because they are not true according to the following scenario.
favorite_color = input("Enter favorite color:\n")
pet = input("Enter pet's name:\n")
num = input("Enter a number:\n")
print("You entered: "+favorite_color+" "+pet+" "+num)
password1 = favorite_color+"_"+pet
password2 = num+favorite_color+num
print("First password: "+password1)
print("Second password: "+password2)
print("Number of characters in "+password1+": "+str(len(password1)))
print("Number of characters in "+password2+": "+str(len(password2)))
This works for me.
