In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second frame

at step 2, rather than at step 1. What rationale might the designers of CSMA/CA have had in mind by having such a station not transmit the second frame immediately (if the channel is sensed idle?

Answer:

There could be a collision if a hidden node problem occurs.

Explanation:

CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.

If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.

This is your code. &gt;&gt;&gt; A = ['dog''red'] &gt;&gt;&gt; B = [' cat', 'blue']&gt;&gt;&gt;C = ['fish', 'green'] You can impl
natima [27]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The given Python code is:

>>> A = ['dog''red']

>>> B = [' cat', 'blue']

>>>C = ['fish', 'green']

We can implement an array of this data by using the dictionary in Python.

Dictionary in python:

A dictionary in python stores (key-value) pairs. For example, we can implement the -given arrays A, B, and C in the dictionary as given below:

d={'dog : red', 'cat : blue', 'fish : green'}

print(d['dog']) # Get an entry from a dictionary; prints "red"

print('cat' in d)    # Check if a dictionary has a given key; prints "True"

d['fish'] = 'black'    # Set an entry in a dictionary

print(d['fish'])      # Prints "black"

# print(d['elephant'])  # KeyError: 'elephant' not a key of d

print(d.get('elephant', 'N/A'))  # Get an element with a default; prints "N/A"

print(d.get('fish', 'N/A'))   # Get an element with a default; prints "black"

del d['dog']        # Remove an element from a dictionary

print(d.get('dog', 'N/A')) # "dog" is no longer a key; prints "N/A"
