Pendrive, CD is local storage divices
Answer:
The correct option : b. new GridLayout(4,3)
Explanation:
The total number of rows are 4 and total number of columns are 3.
So the total keys can be added is 4*3=12. This is suited for telephone keypad.
B. it can save time by allowing you to quickly fill cells
Answer:
I wrote this myself, it should be working. I think this is what the instructions were looking for.
The code below should return
Squared: 1296
Mod: 0
Quadrupled: 16
Explanation:
def threeParams(squared, mod, quadruples):
array = [squared, mod, quadruples]
array[0] = squared ** 2
array[1] = mod % 5
array[2] = quadruples * 4
return array
valueArr = threeParams(36, 15, 4)
print(f"Squared: {valueArr[0]}\nMod: {valueArr[1]}\nQuadrupled: {valueArr[2]}")
Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
