Complete Question:
The main disadvantage of using this device is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.
Group of answer choices
a. Router
b. Switch
c. Bridge
d. Hub
Answer:
d. Hub.
Explanation:
A hub can be defined as a layer one (physical) device used for connecting various network devices such as switches and routers in a local area network (LAN). It comprises of many ports which are used for connecting segments of a local area network (LAN). Hubs are generally considered to be unintelligent because when frames are received at a port, it is then copied to every other connected port on the network.
<em>Hence, the main disadvantage of using a hub is its negative impact on network performance, resulting from the fact that any incoming signal on any of its ports is re-created and sent out on any connected ports.</em>

Answer:
count_land = count_air = count_water = 0
while True:
s = input("Enter a string: ")
if s == "xxxxx":
break
else:
if s == "land":
count_land += 1
elif s == "air":
count_air += 1
elif s == "water":
count_water += 1
print("land: " + str(count_land))
print("air: " + str(count_air))
print("water: " + str(count_water))
Explanation:
*The code is in Python
Initialize the variables
Create a while loop that iterates until a specific condition is met. Inside the loop, ask the user to enter the string. If it is "xxxxx", stop the loop. Otherwise, check if it is "land", "air", or "water". If it is one of the given strings, increment its counter by 1
When the loop is done, print the number of strings entered in the required format
