Explanation:
A hub is used to send the message from one port to other ports.It does not know the specific address of the destination where the message needs to send.it works on Physical layer of the OSI model(layer 1).
A switch can handle data and it knows the specific address of the destination.A switch works on the data link Layer of the OSI model(layer 2).
Because it ‘computes’ certain tasks, get it. It’s like saying ‘the puncher’ for someone who punches stuff.
Answer:
speed = float(input("Enter the speed: "))
hours = int(input("Enter the hours: "))
distance = 0
for i in range(hours):
distance += speed * 1
print("The distance after " + str(i+1) + ". hour(s): " + str(distance))
Explanation:
*The code is in Python.
Ask the user to enter the speed and the hours
Initialize the distance as 0
Create a for loop that iterates hours times. Inside the loop, calculate the cumulative distance traveled at the end of each hour and print it (Note that the distance = speed x hour)
Answer:
D. Low-level components are combined into clusters that perform a specific software sub-function
Explanation:
Normally, regression testing are done on a manual basis by simply re-executing a subset of the entire available test cases or it can be done automatically by utilizing playback tools or automated capture. Hence, from the options, a combination of low-level components into clusters that perform a specific sub-function does not align with how regression testing are done either manually or automatically.
