A throw(...) statement is an alternative way to return from a function or method that indicates some kind of failure occurred.

WITCHER [35]

Answer:

a.True.

Explanation:

A throw statement is used to throw an exception from inside the method.Whenever the throw statement is encountered by the compiler and after that when it is executed the execution of the currently executing method is stopped and it returns back to caller.

There is also a keyword Throws which is used to tell the compiler that the method may throw one or more exceptions.

Hence we conclude that the answer is True.

find_cow(name, cows) Given a name and a Python list of Cow objects, return the Cow object with the specified name. If no such Co

nadya68 [22]

Using the computational knowledge in python it is possible to write a code that Given a name and a Python list of Cow objects

<h3>Writting the code in python:</h3>

def load_cows(filename):

cow_dict = dict()

f = open(filename, 'r')

for line in f:

line_data = line.split(',')

cow_dict[line_data[0]] = int(line_data[1])

return cow_dict

def greedy_cow_transport(cows, limit=10):

trips = []

cowsCopy = cows.copy()

sortedCows = sorted(cowsCopy.items(), key=lambda x: x[1], reverse = True)

while sum(cowsCopy.values()) > 0:

total = 0

for cow, value in sortedCows:

if cowsCopy[cow] != 0 and value + total <= limit:

ship.append(cow)

total += value

cowsCopy[cow] = 0

return trips

A T-1 system multiplexes ___ into each frame

zimovet [89]

Answer:

PCM encoded samples from 24 voice band channels

Explanation:

The Multiplexer from a lot of inputs generates one single output. And it is the select line that determines which of the input is going to influence output. And the select lines determine the increase in the quantity of data that can be sent through the network in a given amount of time. And this is termed as a data selector. Please note, this is application of multiplexer in data transmission.

And now coming to the T1 carrier system, it is a time division multiplexor, which multiplexes the PCM encoded samples coming from 24 band channels that require to be transmitted over an optical fiber or single metallic wire pair. And for this question, we need what is being multiplexed, and that is as mentioned in the Answer section.
