Answer:
Behaviour
Style
Structure
Explanation:
Above are the three primary separation of concerns for a web application at client side.
Structure --> we can define the structure of the application at client side using HTML
style-->style is used to give some styling information like font,color,headings so on at client side .In general we use CSS to do this at client side
Behaviour--> it actually defines the functionality of the elements at client side like when we click button what it should do.We will use JavaScript to define the behaviours at client side
Answer:
negatives = []
zeros = []
positives = []
while True:
number = input("Enter a number: ")
if number == "":
break
else:
number = int(number)
if number < 0:
negatives.append(number)
elif number == 0:
zeros.append(number)
else:
positives.append(number)
for n in negatives:
print(n)
for z in zeros:
print(z)
for p in positives:
print(p)
Explanation:
Initialize three lists to hold the numbers
Create a while loop that iterates until the user enters a blank line
Inside the loop:
If the number is smaller than 0, put it in the negatives list
If the number is 0, put it in the zeros list
Otherwise, put the number in the negatives list
When the while loop is done, create three for loops to print the numbers inside the lists
Answer: Crossover
Explanation:
Based on the information given in the question, the type of cable that should be used is the crossover cable.
Crossover cable is used for a direct connection of computing devices. A crossover cable is typically used for the connection of computing devices that are of identical types.
Since the LAN port on a router is to be connected to the uplink port on a switch and the switch does not support auto-MDI, the crossover cable can be used.
Answer:
backing up files and other data
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.
